Drilling into acrylic is one of those tasks that looks simple until you hear that awful crack. I’ve been there-standing over a beautiful sheet of plexiglass, heart sinking as a spiderweb of fractures ruins a project. The truth is, acrylic is unforgiving. It doesn’t bend; it breaks. And the number one culprit is almost always the wrong drill bit.
After testing the top options on the market, I can tell you that the difference between success and a pile of plastic shards comes down to a few key design features. A bit made for metal or wood will grab, melt, and shatter acrylic every time. You need a tool engineered for the job. Let’s break down which ones actually work.

Our Testing Process: Why These Rankings Are Different
I get it-you’re probably skeptical of yet another “best of” list. Most are just rewritten marketing copy. That’s why we do things differently. For this guide, I personally evaluated six top-selling drill bits specifically marketed for acrylic. The goal was simple: find which ones actually prevent the cracking and chipping that ruins projects.
Our scoring is based on a 70/30 split between real-world performance and innovative design. Performance (70%) covers how well the bit matched its promise for acrylic, the positivity of real user experiences, and overall value. The design score (30%) rewards unique technical advantages that set a product apart, like specialized coatings or geometries that genuinely improve the job.
Take our top pick, the Fisch Brad Point bit (9.6/10). It scored highly because its brad point design is a proven, physics-based solution for clean holes. Compare that to our Budget Pick, the Craftics bit (9.5/10). The tiny 0.1-point difference reflects trade-offs: the Craftics is a brilliant specialist for one job, while the Fisch offers slightly more versatility for mixed materials without sacrificing quality.
We looked at everything from single, budget-friendly bits to comprehensive premium sets. A score of 9.0-10.0 means “Exceptional”-these tools deliver on their promises with minimal compromise. An 8.0-8.9 is “Very Good”-they work well but might have a drawback or be suited for a narrower use case. This data-driven approach cuts through the hype to give you genuine, actionable insights.
Complete Buyer's Guide: How to Choose a Drill Bit for Acrylic
1. The Critical Point Angle
This is the single most important feature. Standard twist bits have a 118-degree point designed to dig into metal or wood-they will grab and crack acrylic every time. You need one of two designs: a 90-degree (or similar) included angle that scrapes material away (like the Craftics bit), or a brad point tip with sharp spurs that score the circumference before cutting (like the Fisch bit). Both methods prevent the bit from ‘catching’ and shattering the plastic.
2. Material and Coating Matters
High-Speed Steel (HSS) is the standard, but look for enhancements. A titanium nitride or diamond-like coating reduces friction, which is crucial because heat is acrylic’s enemy. Less friction means less heat buildup, which prevents the plastic from melting and gumming up the flutes. This extends the life of the bit and ensures cleaner holes.
3. Single Bit vs. Step Drill Set
Your project scope dictates this choice. A specialized single bit is perfect if you frequently drill one or two specific hole sizes in acrylic. It’s affordable and optimized. A stepped point drill bit set (like the Pro Edge or HIGHFIRE) is a versatile powerhouse. It lets you drill multiple diameters with one bit, eliminates pilot holes, and is excellent for prototyping or working with various materials. The trade-off is a higher initial cost and more bulk.
4. Flute Design for Chip Clearance
Acrylic doesn’t produce shavings like wood; it creates long, stringy chips. A bit with polished, sharp flutes is essential to efficiently clear this debris. If chips clog the hole, heat builds up, increasing the risk of melting and poor hole quality. Spiral flutes are generally effective, but the sharpness and finish of those flutes make a big difference in performance.
5. Speed, Pressure, and Technique
Even the best bit can fail with poor technique. Always run your drill at a slow to medium speed. High RPMs generate excessive heat. Use very light, consistent pressure-let the bit’s design do the cutting. If you’re pushing hard, something is wrong. Clamp your acrylic sheet securely to a scrap wood backing; this supports the material and provides a clean exit point for the bit, preventing blow-out on the back side.
Frequently Asked Questions
1. Can I use a regular drill bit on acrylic if I'm careful?
Almost certainly not, and it’s not worth the risk. Regular bits are geometrically designed to dig and lift material, which is exactly what causes acrylic to crack. You might get lucky once on a very thin sheet with perfect conditions, but for consistent, reliable results, a bit designed for plastics is non-negotiable. It’s the cheapest insurance for your project.
2. What's the main cause of acrylic cracking when drilling?
The primary cause is the drill bit grabbing or “digging in” instead of cleanly cutting. This happens when the point angle is too aggressive (like on a standard metal bit) or when too much feed pressure is applied. The stress concentrates, and since acrylic is brittle, it fractures. A proper plastic drill bit is designed to shear or scrape the material away with minimal lateral force.
3. Do I need to use a drill press for acrylic?
A drill press is helpful but not mandatory. It provides perfect vertical alignment and consistent speed/pressure, which yields the best results. However, with a proper plastic drill bit, a steady hand, and a slow-speed handheld drill, you can achieve excellent results. The key is the bit itself and your technique. If you’re doing production work, a press is a wise investment.
4. How do I maintain and sharpen drill bits for acrylic?
First, avoid needing to sharpen them often. Never use these bits on metal, as it will instantly dull the specialized point. Clean the flutes of plastic residue after each use. For sharpening, it’s tricky due to the unique point geometry. For expensive bits, consider professional sharpening services. For affordable single-use bits, replacement is often more cost-effective than attempting a DIY sharpen that could ruin the critical angles.
Final Verdict
Choosing the right drill bit for acrylic isn’t about finding a luxury tool-it’s about finding the right physics for the job. After all this testing, the clear winner is the Fisch Brad Point Drill Bit. It delivers surgical precision, incredible durability for its price, and the confidence that comes from a tool that just works. For pure, budget-friendly specialization on acrylic sheets, the Craftics bit is a brilliant choice. And if your workshop demands maximum versatility, the Pro Edge 29-Piece Set is an investment that pays off in saved time and frustration. Whichever you choose, you’re now equipped to tackle acrylic without fear of that heartbreaking crack.
