You may assume that acrylic is just plastic. But acrylic is tough plastic-like glass, with glass traits, but with a significant difference in weight. Ordinary metal and wood drill bits may not curve out holes uniformly in this material. So you need to find the best drill bit for acrylic for the job.
First, the bit geometry for the ordinary bits and those for acrylic are different. For instance, the tip angles for acrylic are half the normal 120 degrees for the other bits. So, when cutting, you don’t have to worry about the material chipping off.
Another thing, using ordinary bits for acrylic tasks may generate so much heat leading to melting and premature wear. To avoid such mishaps, you need the right drill bits. Check out our suggestions of top-quality acrylic bits for a fast and clean job.

How to Choose Best Drill Bit for Acrylic
Acrylic bits have a few special features from ordinary bits. These traits may affect the quality of finish, speed of drilling, and the ease of chip removal. When drilling holes for screws, you also need to make larger holes since plastics tend to expand and contract easily.
It is also advisable not to let the chips accumulate, so a drill press with a slow feed rate and removal ensures that the bits work efficiently. What are the considerations for the right acrylic bits?
Let’s dive in.
Tip Angular Design
Unlike the other drill bits with a 120otip, tip angles for acrylic bits range between 60-90o. The reduced angles with sharp knife-like edges ensure uniformity in drilling with no cracks.
Drill bits with step-like tips tend to be fast at chip removal compared to ordinary tips.
Drill Bit Construction Material
High-speed steel drill bits are strong and durable. But diamond or titanium-coated have extra cutting ability and are more durable. If you use ordinary drill bits on acrylic, the material chips off or in some cases melt away.
You should therefore buy special drill bits for plastic or acrylic to drill neat and smooth holes.
The flute clears chips from the way of the hole. It also determines the accuracy and depth of drilling. Not all flutes are effective in both functions. Split point tips and brad points have sharp cutting edges and may be suitable for cutting through the acrylic.
You may also select acrylic point drill bits that are tagged as such.
Frequently Asked Questions about the Best Bit for Acrylic
In this section, we respond to relevant questions concerning acrylic drill bits and their special features. Let’s dive in.
Q: What is the best type of drill bit for acrylic?
A: The ordinary wood and metal bits are not suitable for the job. However, special bits for acrylic with a particular tip geometry, flute, and diameter size determine the finish on your acrylic sheets.
Diamond-coated and titanium drill bits are persistent and have a smooth cutting on acrylic compared to wood and metal bits.
Q: Can I drill a hole through acrylic?
A: You can drill a hole through acrylic using acrylic drill bits. Mark off the surface with masking tape, and put a small pilot hole before drilling with the larger diameter bits. The masking tape prevents the chips from flying off randomly. Since acrylic expands and contracts faster, the holes for screws should be slightly large so that after cooling, the screws will fit in.
Also, it is advisable to use a thin plywood sheet to support your material, so that it does not chip on the lower side. Besides, you should have protective gear like goggles to avoid the chips from getting into your eyes.
Q: What kind of drill bit is used for plexiglass
A: Drill bits for plastics such as ABS, lucite, and acrylic can also cut through plexiglass material. The tip angles should range between 60- 90 degrees.
