drilling thick acrylic

Water, kerosene, mineral oils and other compatible solvents can be used. 2. Precautions should be taken to protect this material from flames and high heat sources. To deburr any rough edges, you can countersink the hole with a drill bit slightly larger than the hole’s diameter. If there are bigger "chunks" use a razor blade and scrape around the hole to remove any burrs then finish with sandpaper. Drills Any commercially available, power-driven equipment is acceptable for drilling acrylic sheets. Specialty drill bits for acrylic use 60 or 90 degree points with zero rake cutting angles. Super CHIPFREE point is precision ground at a 60 degree angle for gradual penetration to avoid cracking and chipping of the acrylic material. Second, the distance from the hole center to the edge of the sheet should be at least 1.5 times the diameter of the. These bits require the same considerations for support behind the sheet and for cooling as previously reviewed for twist drills bits. However, in many fires sufficient air will not be available and toxic carbon monoxide will be formed, as it will when other common combustible materials are burned. Larger tip angles commonly cause cracking and blow out as the bit exits the sheet. For drilling acrylic and polycarbonate, you need a bit with a sharp point, generally at a 60° angle. Spade drill bits can also be used with satisfactory results. In certain hole depths and sizes, coolants are necessary to prevent melting. Drilling into plexiglass requires a few additional steps that are not found when drilling into wood or metal. The customer is not released from the obligation to conduct careful inspection and testing of incoming goods. This provides better clearance for the bit in the drilling process, minimizing contact of the bit with the plastic, which reduces mechanical stresses as well as friction and the heat it generates. That’s a real problem because chips can propagate into cracks. These products are sold under the registered trade name ACRYLITE® in the Americas and under the PLEXIGLAS® trade name on the European, Asian, African and Australian continents. 0 Reviews. To drill a hole in ACRYLITE® sheet greater than 1” (25.4 mm), a circle cutter may be used. Plexiglass, Lexan, Plastic Drill Bits These are the bits you need for drilling Plexiglass, Lexan polycarbonate, PETG, and other clear plastics. The previous sections dealt with controlled production and shop applications. The scrap sheet of material relieves any pressure on the plastic, which minimizes chipping and cracking. Acrylic and plastic are soft materials by nature, and power tools should be used with care. What’s more, use of a lubricant will result in a smoother finish of the hole. Never attempt to use a circle cutter with a hand-held electric drill. See figure 4. 1” holes should be drilled no faster than 450 rpm. A backing piece of wood or acrylic will make a neater hole. Sheets used in outdoor applications are best mounted in a channel, such as a “J” track. Optimum conditions result in smooth surface holes with smooth, continuous chips. Appropriate drilling conditions are a combination of both spindle rotation speed (RPM) and feed rate (IPM). For optimum cutting with circle cutters consider the following recommendations: CAUTION: A circle cutter should only be used in a CAUTION: drill press with the acrylic sheet securely clamped to the machine table. They require maximum support behind the sheet during use to prevent cracking. Next, mark the location of the hole with either a grease pencil or permanent marker. You can use a standard steel drill or an HSS drill to create your holes. First, place the plexiglass on a thick piece of scrap wood you won’t mind drilling into. The cutter bit must also be modified to accommodate the material properties of acrylic. Circuit board drilling is a special case where automated machines drill thousands of tiny holes at very high speed. It takes a special drill bit to properly drill through Plexiglas, Lucite, Acrylite, or Perspex acrylic sheet. These bits have a different geometric structure that is designed to puncture acrylic more easily and they are less likely to melt plexiglass. and get all the latest news, trends and offers straight to your inbox. Even a small hairline fracture will result in a crack at some point." The drill made the job of drilling acrylic plexiglass much easier. Start with a small drill bit (See link below to pilot holes) and work up to the size you require. White, colors, clear acrylics, cast, AR, LD etc. To make it easier to … If possible, you can also clamp the acrylic sheet along the borehole/boreholes by placing one or more slats along the boreholes and clamping them with glue clamps. Increasing bit tip angle decreases the size of generated chips, facilitating chip ejection. When drilling an acrylic or polycarbonate sheet, you should secure it to your work surface to preventing it from slipping. Before drilling, it’s best to clamp down the plastic securely to a solid surface and back up the piece you are drilling with a spare piece of plywood underneath. Taking breaks allows the plexiglass to cool thus reducing the risk of damage. Also use a smaller diameter drill bit to pilot drill the … Acrylic chips can easily fly off during drilling and be a health hazard. Step 4 Always drill the hole 1-2 mm larger than the fastening (i.e. Any commercially available, power-driven equipment is acceptable for drilling acrylic sheets. The special tip design carves through the plastic (not for use with wood or metal). Acrylic Plexiglass sheet, rod, tube - in stock - at large plastic supplier. All rights reserved. Standard point drill bits grab too much and chip the hole edges. Do not force the bit into the acrylic let it cut under its own weight and should the drill bit get stuck in the platic sheet, put the drill into reverse to get it out. When the hole has been completed and the “blank” has freed itself, turning the drill press off without removing the cutter, is desirable in order to prevent any chipping of the hole during tool exit. The tip must scrape the acrylic, not gouge it. Manual drilling operations should be performed at slower speed and feed rates than automated or CNC drilling taking into account the diameter of the bit, material thickness, and ability to cool during drilling. Have Acrylic cut to size at Curbell Plastics. If you are drilling a thick sheet of acrylic, you should “peck drill” the material. For the best experience on our site, be sure to turn on Javascript in your browser. ACRYLITE® Sheet Distributors may also offer materials and equipment. Be sure to follow the manufacturer’s safety recommendations for equipment and materials used with ACRYLITE® sheet. 7pcs Ceramic Nail Drill Bits Set Pedicure & Manicure Drill Bits Kit Replacement Drill Bits for Electric Nail Drill Machine Acrylic Nail Tool. I used a 1/8 bit to pierce the acrylic then stepped up with standard bits, which seems to work fine. As mentioned above, chip ejection becomes more difficult as the hole gets deeper. Special Hi-Molybdenum tool steel, gold surface treated body, flute and point for maximum lubricity. Second, the distance from the hole center to the edge of the sheet should be at least 1.5 times the diameter of the drilled hole. When drilling acrylic be sure to use a good quality HSS drill bit. Unibit® or Vari-Bit® Step Drill (1/8" to 1/2") - these bits can be used for sheets up to 0.118" (3 mm) thick to achieve a variety of hole diameters with a single bit. Paper and film masking prevent damage to the sheet. One difference between the types of drill bits is the angle of the tip. A spindle speed of between 400-600 rpm is recommended. This point angle must be ground to 60-90°. Sign in to access your web account. when your using a hole saw pre drill the guide drill hole first when you don't have a backing under where your drilling because when it hits through the opposite side its going to pull the bit in. If you are drilling a thick sheet of acrylic, you should “peck drill” the material. Do not remove the surface protection masking prior to fabrication. Drill with normal speed and a spray bottle full of water to keep bit cool. The cutting edge must be ground “flat” to a 0-4° rake angle. 1 UK only; 2. For the best experience on our site, be sure to turn on Javascript in your browser. Holes that may be subject to force from screws or bolts should be deburred with a countersink. When drilling plastic, the larger the hole, the slower drill speed you should use since high speeds can melt the plastic. However, it implies no liability or other legal responsibility on our part, including with regard to existing third party intellectual property rights, especially patent rights. Thin or thick sheets. Zero flute countersinks work well for the countersinking and deburring of holes in acrylic sheet. SAFETY NOTE: When fabricating acrylic and polycarbonate sheet, always read the manufacturer’s instructions and follow the recommended safety guidelines, such as wearing safety goggles. This back relief reduces metal/plastic contact and heat build-up. Worked perfectly. Please see the picture to the right for a detailed diagram. Be sure to firmly chuck the drill bit in the cordless hand drills or drill press. Here is a video on how to properly drill through acrylic plexiglass. H>D, larger chips become more difficult to eject because of the close clearance between the bit and the hole walls. See Figure 2. However, as mentioned above, if the tip angle is too large, larger than 90°, blow out and chipping may be a problem when the bit exits the acrylic. it should only take a few seconds to go through 3/8" thick acrylic. They leave a poor finish on the inside hole. Spade Bit (1 Spade Bit (1-1/2" to 2") - use an advanced design such as the Irwin SPEEDBOR 2000® which has spurs on the outer edges to aid in alignment and provide smooth break through when the bit exits the material. These metal drill bits have ground flukes with 90 degree points and 0 degree rake. It is therefore essential to reduce generated heat and to remove chips quickly. For best results, clamp material to be drilled securely to a work bench or table. If you are drilling through several sheets of plastic, you will most likely need to use some type of coolant, such as water, to dissipate the heat that will build up. See figure 3. It is difficult to precisely control feed rate in manual drilling operations. If chips are crumbly and the cut is uneven, the feed rate is too high or RPM is too low. Drilling Holes in Acrylic. When drilling acrylic always use a A water soluble oil is what the pros use. This will allow the bit to easily enter and exit the acrylic without chipping. You should also back up the plastic piece with a scrap of plywood or MDO. Is it any more difficult to drill 1" thick acrylic compared to 1/2"? Chips that are molten and holes that show melting indicate that feed rate is too low or RPM is too high. This includes portable drills, drill presses, lathes, automatic multiple-spindle drilling units, CNC routers and machining centers. This modification is standard on most high quality twist drill bits. These bits come in a variety of diameters at home improvement or hardware stores. Standard metal-working drill bits are designed to aggressively cut into metal as they are fed into it. Hole finish can be used as a guide for appropriate feed rates once the correct RPM is established. Cutting tool must only be extended enough to achieve the desired depth of cut. Friction between the bit and the material also increases because of acrylic’s relatively low thermal conductivity and high thermal expansion coefficient, which cause the material to expand. The holes must have clean crisp edges. These materials may include cleaners, polishes, adhesives, sealants, gasketing or packaging materials, cutting emulsions, etc. Sign In. Like other plastic materials, ACRYLITE® sheet is subject to crazing, cracking or discoloration if brought into contact with incompatible materials. The back relief angle of the cutting edge should be ground away at a 10° to 15°. The work piece should be held firmly or, preferably, solidly clamped to the worktable. This will prevent chipping of the bottom surface. Catherine G. October 8, 2019. This cutting edge will scrape the acrylic, not gouge it. Helix angles, which are too large, can cause cracking around the hole edges. When drilling ACRYLITE® sheet, heat is generated due to the close clearance between the bit and the hole walls and because of the difficulty of chip ejection. In most instances, when drilling an acrylic material, you will use a tool commonly known as a drill bit, which also varies in size. Additionally, peck drilling should be employed in deeper holes to reduce melting. Larger diameter bits and bits with smaller tip angles produce larger chips. To prevent cracking, holes should not be drilled at a distance closer to the edge of the sheet less than 1-½ times the diameter of the hole itself. However, when you are drilling a ¼” hole, the recommended speed of the drill should be reduced to 1,800 rpm. Add to list . These drill bits must be reground in order to scrape the plastic instead of sharply cutting into the material and gouging it. screw or bolt) to allow for thermal expansion and contraction. If hole depth (H) is less than bit diameter (D), large chips are easily ejected. Do not try to pull it out. This allows for adequate clearance for thermal and moisture expansion and contraction. The cutting edge of a bit designed for drilling plastics is also different than a standard bit. Coolants reduce generated heat, and therefore improve hole quality. Tangee always provides excellent service. JavaScript seems to be disabled in your browser. Two parameters are usually employed for determining these. When you have a hole saw attached when it pulls in its going to slam against the acrylic and chip and in some cases shatter the acrylic on thinner walled tanks. I didn’t even know you could get drill and tap combined. This is to ensure smooth, vibration-free drilling because large bits will tend to grab the material more. T&C's apply. The products of combustion, if sufficient air is present, are carbon dioxide and water. hole. The fly cutter and cutting tool itself must be secured properly. The surface behind the cutting edge must be ground away to clearance angles of 12-15°. Any difference in technique? Plastic drill bits can drill through plastic. A standard drill bit typically is at flat 120° angle. Plastic drill bits shave or scrape plexiglass, acrylic or plastic away layer by layer. for D=0.250", a coolant should be used for H>0.250"). Roehm America LLC Acrylic Products 1796 Main Street Sanford, ME 04073 USA Phone +1 800 631-5384 www.acrylite.co. As the depth of the hole increases, i.e. As indicated in the graphs and table above, lower SFM’s are required for larger drill bits. The back relief angle of the cutting edge ensures that the drill bit designed for plastic shaves slivers of material rather carving away large chips that could propagate cracks. See the Tech Briefs in this series for more information, or contact your ACRYLITE® sheet Distributor for information on a specific product. Very excited to have some of my old music up on Spotify finally. Understanding this information is invaluable for many hole making requirements. It is best to backup the piece being drilled with acrylic, other thermoplastic sheet or medium density fiberboard (MDF) so the drill bit will continue on into solid material as it penetrates the bottom surface. I need to drill precision holes in 3mm to 12mm" thick acrylic. A light misting of water is also recommended to keep the cutter and plastic cool, and also to act as a cutting lubricant. Tip angles on standard drill bits are commonly 118-130°. Test Methods: Mechanical Properties of Plastics.). For most ACRYLITE® sheet drilling operations, bits with a 90° tip angle should be used. Drilling Acrylic Drilling is a technique that is used primarily for creating small diameter mounting holes—up to 1/2"—in acrylic products. Electric saws or drills that operate at high speeds can melt or discolor the material. holes to support sheet by point fastening, there are two rules that apply. A slow feed rate helps reduce the incidence of chipping. Additionally there are times that holes need to be made, such as at a job site, where there is limited control of the exact speeds and feeds that are being used. According to Alison Svoboda of Boda Corporation, "polycarbonate  is "notch sensitive" so a sharp drill bit is imperative. Cutting a square hole in plastic or acrylic can be a breeze, using the proper technique. As a general rule, coolants should be used when the depth of the hole (H) exceeds bit diameter (D) (e.g. Welcome Back! Authorized Cf. Feed rate and RPM recommendations are provided in figures 8 and 9. A slow, steady feed rate is very important to achieve a clean, smooth hole. grades. Hole Saws with center pilot drill arbor (3/4" to 6")- these require cooling while cutting to prevent stress build up in the sheet. This information and all further technical advice is based on our present knowledge and experience. Coolants should also be used for holes greater than or equal to 1/2" in diameter (D ≥1/2"). Metal-working high-speed steel twist drill bits can be used with some modification. Very glad we purchased this item. The holes range from 0.6mm to 3mm in 0.2 increments. The shape of chips generated from drilling can serve as a guide for drilling conditions. The gradually go up in drill bit sizes until you reach your desired diameter. See figure 1. If you're going to be cutting a lot of acrylic or are using very expensive (thick) material, you need to invest in a blade specifically designed for cutting plastics and laminates. As a general rule of thumb, the recommended speed of the drill should be reduced as the size of the hole drilled increases. Generally, bits with a 90° tip angle are recommended. Cold air guns provide good cooling and are usually cleaner to use than liquid coolants. ACRYLITE® sheet usually burns rapidly to completion if not extinguished. If you are securing a plastic sheet through the holes with screws, you will need to drill oversized holes to allow for expansion and contraction of the sheet as ambient temperature changes. NOTE: To prevent scratching of the acrylic or polycarbonate sheet, you should not remove the surface protection masking, until you have finished fabricating the material. If a countersink is unavailable, use a drill of larger diameter than the hole and deburr the rough edge on the exit side of the hole (side where the drill came through the sheet). Acrylic may be stronger than regular glass, but it's still brittle! Use a blunt metal drill or back off the rake angle. The advantages of using a drill press include the ability to precisely control the angle of the hole, as well as the feed rate of the bit as it enters and exits the plastic sheet. There are three points to consider when modifying a standard metal-working twist drill for plastics: 1. Bits with 60° tip angles are also used, especially for holes with diameters of 1/2" and greater. If you’re working with a thick piece of acrylic, you can use conventional drill bits if you first place a piece of masking tape over the area to be drilled. The drill press provides the uniform pressure and constant positioning essential for a safe drilling of quality holes. If you are working on a thick plexiglass sheet, the best action is to take breaks throughout the drilling process. 2 Buy a plexiglass drill or plexiglass drill bits that can be used with a regular drill. The good thing with this technique of material fabrication is that it makes it possible for you to attain relatively uniform holes. Be sure to … Then place a piece of masking tape over the mark. Typically a helix angle of 15-30° is recommended. Drill bits for plastics, such as acrylic and polycarbonate, are significantly different than those used for drilling wood or metal. When drilling larger holes in a thicker piece of plastic, you will need to take additional precautions. The lubricant will also help expel any of the plastic chips from the hole as you are drilling. It has an advantage over a spade bit because it has a helical flute design which will pull out chips. Step 3 Put on your safety glasses and secure the drill bit into the chuck of the drill motor. First you need to drill a small diameter pilot hole to get started. Röhm GmbH and its affiliates are a worldwide manufacturer of PMMA products sold under the PLEXIGLAS® trademark on the European, Asian, African and Australian continents and under the ACRYLITE® trademark in the Americas. Place the sheet on a flat surface that supports it well and which the drill can run in to, for example, a wood board. Also, always reduce the drill speed as the drill bit exits the material. First, the bolt hole diameter should be at least 2 times the diameter of the bolt. What this means is to drill a little of the hole at a time, repeatedly removing the bit from the hole to extract the shavings. Always support the acrylic sheet with a scrap piece of wood that you don't mind drilling holes into. If used on acrylic without modification, these bits will chip and cause other damage to the plastic. However, liquid coolants provide more cooling, as the liquid can trickle down the hole as the bit goes through the material, resulting in better hole finishes. 3. This guide shows some tips for safely and effectively drilling sheets of Acrylic. For H>D, peck drilling, drilling in increments and removing the bit from the material periodically to clear chips, should be employed. Not only does this practice prevent the accumulation of debris resulting in the drill bit from binding in the hole, but it also avoids the build-up of heat and melting of the plastic. Holes which may be subject to forces from screws or bolts should be deburred with a countersink. Using the wrong type of bit can result in the tool grabbing as you are drilling, which can lead to chipping at the edge of the hole. Zero flute countersinks work well for countersinking and deburring holes in acrylic sheet. may chip the back side of the acrylic. Careers; Locations; Ask a Plastics Expert; Cart Item Added Go To Cart. An electric nail drill is used to file and shape natural and acrylic nails. For instance, if the acrylic is 5mm thick, then the distance from the edge where you will drill is 10mm. The helix angle on a bit is the angle between the cutting edge and a vertical line along the center of the bit. This is very interesting, I recently built a box with acrylic sheet, it was 5mm thick sheet and I was drilling and hand tapping 2mm threads edge on! We reserve the right to make any changes according to technical progress or further developments. When drilling holes to support sheet by point fastening, there are two rules that apply. Offar expiras 23:59(GMT) 10/02/16; 3. They also do not produce clean interior surfaces so they won't work. Small helix angles interfere with chip ejection, increasing melting. Bit geometry affects the quality of drilled holes since it affects chip size and chip evacuation. The material should also be placed as close to the fly cutter as possible to reduce the distance the cutter has to travel. ACRYLITE® sheet is a combustible thermoplastic. If you just drill a pilot hole then jump right to a big size bit you will likely crack the plastic. ACRYLITE® sheet must be adequately supported and clamped to prevent flexing or vibration during the cutting operation. Placing a backing block of scrap acrylic, mdf, or plywood panel under the drilling point will add extra help to prevent chipping when the bit breaks through. If the sheet is thin, use a step drill bit instead. Reference to trade names used by other companies is neither a recommendation, nor does it imply that similar products should be used. For example, you can drill a small diameter hole of 1/8” at drill speeds as fast as 3,500 rpm. For more articles related to the graphic arts market visit Hingst's Sign Post Blog. Both types of masking allow you to draw on the surface as you lay out your job. Please see the picture to the right for a detailed diagram. A bit with a 90° tip angle will generate smaller chips which are easier to evacuate, reducing melting and improving hole quality. If the drill bit is new, wear it in a little on a scrap piece of wood so that there is no risk of the sharpness tearing the acrylic. If the material chips, feed rate is too fast and must be decreased. I used a modelling drill in a stand to ensure that I got perfectly perpendicular holes, I used hand taps with a little Vaseline. When drilling acrylic, it is important that the sheet is well supported. The water acts as a coolant, helps to reduce heat build up, and creates holes with smoother walls. Drill bits are made of high-speed steel (HSS), cobalt, HSS with carbide tips or solid carbide. Just use a piece of sand paper to go over hole after you drill it. The suppliers listed below offer materials and equipment tested and approved by Roehm America LLC. For instance, you can drill mounting holes in items, such as plaques, certificate covers, control panels and signs, which enable you to attach the product to another surface using screws or other hardware. This allows for adequate clearance for thermal and moisture expansion and contraction. As a result, feed rate must generally be slowed down in order to prevent chipping and consequently spindle speed must be reduced to prevent melting. Continuous drilling causes excess heating which melts and damages the sheet. We urge good judgement in the use of this versatile material and recommend that building codes be followed carefully to assure it is used properly. Copyright © Roehm. Several drill bit geometries are described below that can be used with success, although most do not leave the inside diameter of the hole with a smooth finish. {{cart.count}} Get a Quote. If you try to drill a sheet of acrylic with conventional metal or wood drill bits, there’s a chance you’ll end up cracking it. Not sold online Available online Out of stock online. Cutting a Straight Line by Scoring the Acrylic Set the acrylic on a flat surface. Use a slow feed rate when starting the drilling action to allow the bit to enter the material and also slow the feed rate as the bit exits the bottom surface to prevent chipping. These factors, if not accounted for, can cause the material to melt and gum, giving less than optimum hole quality. Specially designed bits are required. The drill bits work well. This includes portable drills, drill presses, lathes, automatic multiple-spindle drilling units, CNC routers and machining centers. If the material melts, feed rate is too slow and must be increased. Sam R. October 8, 2019. In these situations, the following bit recommendations may be helpful. These measures include drilling a pilot hole first. 1-800-553-0335. Care must be taken at the points of entry and exit. They are: For drilling acrylic the recommended values for SFM and IPR are given in the table below. In particular, no warranty, whether expressed or implied, or guarantee of product properties in the legal sense is intended or implied. Place the 1x4-inch piece of wood across the acrylic sheet and secure the plank to the top of the acrylic sheet by clamping one pair of self-locking pliers to each side of the acrylic sheet. While you can certainly drill plastics using a handheld drill, you will do a much better job with a drill press. (Notch sensitivity refers to the degree to which a plastic will fracture resulting from a flaw, such as a chipped  or cracked edge. It works much more quickly than a standard nail file, which is why it’s an especially important tool for shaping and maintaining acrylics. Brad Point Bit (1/8" to 1") - this design is similar to a twist drill with a modified tip similar to a spade bit with spurs. Not sold in stores . They are useful for rough passage holes for installation of HVAC, plumbing or electrical wiring. Several manufacturers offer drill bits designed especially for plastics. When drilling a stack of acrylic sheet (1/4" thick or greater), use water as a cutting fluid. Bits with a moderate helix angle aid in chip ejection and are recommended for drilling of plastics. Air or liquid coolants should be used whenever possible. Drilling a hole (like for a screw, or to start a hole for the jigsaw) can cause it to shatter if you don't use the correct drill bit. Performance of the product described herein should be verified by testing, which should be carried out only by qualified experts in the sole responsibility of a customer. Price Price.
