Best drill bit for perspex: use slow speed HSS or diamond grit for clean, crack-free holes.
You’ve got a clear sheet of perspex and a hole to make without cracks, chips, or melted edges. I’ve drilled acrylic for signs, enclosures, and craft projects. I know heat and chatter ruin cutouts. The best drill bit for perspex avoids heat, clears chips, and gives smooth edges. In this guide I show tools that work, how to use them, and tips I trust. Readable steps, calm advice, and hands-on tests help you pick the best drill bit for perspex for your project whether you use a hand drill or drill press.
TITGGI Carbide Masonry Bit Set
10-piece carbide-tipped set for glass, brick, plastic and tile

Overview
This TITGGI 10-piece set uses industrial carbide tips to penetrate hard surfaces like tile and brick. The bits span 1/8″ to 1/2″ and handle glass and some plastics with steady, slow drilling. I like them when I need robust tips without frequent re-sharpening. Use low speed and cooling when drilling perspex to avoid melting.
For perspex work, the bits cut clean when slowed and cooled. They are built for tough jobs, so they can be overkill for thin acrylic. Still, this set is a durable option if you mix materials and need a versatile kit for perspex and masonry.
Advantages
- Durable carbide tips resist wear
- Wide size range 1/8″–1/2″
- Good for mixed-material projects
- Economical 10-piece set
- Works with low-speed drilling for perspex
Limitations
- Designed for masonry, not specialized for perspex
- Risk of melting acrylic if run at high speed
- Can be brittle if used with side pressure
Our Recommendation
I recommend this set for DIYers who cut a mix of masonry and plastics. If you often drill perspex and tile in one project, this gives versatility. For pure acrylic work, pair with low speed and cooling. It’s a practical choice when you want multi-material value and still need the best drill bit for perspex in your toolbox.
Best Use Cases
| Best for | Why It Works |
|---|---|
| Mixed-material jobs | Good when working on brick and acrylic in the same project. |
| Home repairs | Strong tips for occasional perspex and tile fixes. |
| Crafting | Use slow speed to make neat perspex holes for displays. |
Diamond Hole Saw Set 10PCS
Diamond grit hole saws for glass, ceramic, and pots — precise cuts

Overview
This 10-piece diamond hole saw set cuts through glass and dense material. I use diamond bits for smooth edge holes and for drilling fragile materials. They stay cool with water and make controlled holes in perspex if you clamp and cool. Run at low RPM and use plenty of water to protect acrylic.
For perspex projects, the set is best when you need large, clean holes and avoid heat build-up. Diamond cups shine on brittle substrates. They do require patient drilling and cooling to be the best drill bit for perspex for larger diameter holes.
Advantages
- Very smooth, clean edges when wet-cutting
- Wide diameter options for larger holes
- Good for brittle and glazed materials
- Long life when used with coolant
- Reduces cracking when used properly on perspex
Limitations
- Requires water cooling and patience
- Slow cutting on thick perspex
- Less effective on very soft plastics without stabilizing
Our Recommendation
I recommend this diamond set for makers needing large, neat holes in perspex or glass. If you want the best drill bit for perspex for big holes, use a drill press, clamp the piece, and keep the bit wet. This set gives clean results but needs care and cooling to protect acrylic.
Best Use Cases
| Best for | Why It Works |
|---|---|
| Large holes | Best for sinks, vents, and rings cut from perspex. |
| Glasswork | Designed for glazing and bottle drilling. |
| Aquarium builds | Use wet drilling for smooth aquarium port holes. |
COMOWARE Titanium Twist Set
16-piece HSS titanium twist bits, hex shank, quick change for plastics

Overview
COMOWARE delivers a 16-piece titanium-coated HSS twist set with hex shanks for quick change. The small sizes 1/16″ to 1/4″ work well for precision perspex holes. I favor titanium-coated HSS for low friction and long life. Use slow speed and light pressure when drilling acrylic to avoid melting and chipping.
These bits are a top pick when you need many small sizes for perspex panels. The hex shank fits drivers and quick-change chucks. For many perspex tasks, this set often acts like the best drill bit for perspex in my box of bits.
Advantages
- Titanium coating reduces friction
- Hex shank quick-change ready
- Good small-size coverage for detailed perspex work
- Affordable multi-piece kit
- Durable for repeated low-speed drilling
Limitations
- Not specialized single-flute plastic bits
- Can melt acrylic if used at high speed
- Smaller sizes can break under heavy load
Our Recommendation
I recommend COMOWARE for DIYers and hobbyists who drill many small holes in perspex. Its titanium coating and hex shanks speed up work and reduce heat. For the best drill bit for perspex tasks involving panels and enclosures, this set offers value and precision when used with care.
Best Use Cases

Tungsten Masonry Black Set 10pc
1/8″–1/2″ tungsten alloy tips, triangle handle set for tile and glass

Overview
This 10-piece tungsten alloy tip set aims at tile, concrete, and glass. The triangle handle case helps size selection on the fly. I use these for tough surfaces, and I slow drills heavily when I reach perspex. The tips cut with strength but need careful feed on acrylic.
For perspex, the set will work in a pinch if you control speed and cooling. It is not the ideal single solution but serves builders who mix heavy masonry and occasional acrylic. With care, these bits can be used for perspex without cracking.
Advantages
- Strong tungsten tips for hard surfaces
- Size range covers many common hole needs
- Compact triangle handle case
- Affordable and widely available
- Works for occasional perspex when used carefully
Limitations
- Not optimized for plastics
- Requires low speed and cooling for perspex
- May score or melt acrylic if rushed
Our Recommendation
I recommend this set for contractors who mainly drill masonry and sometimes perspex. It’s rugged and affordable, but for pure acrylic work I’d choose a plastic-specific or HSS set. If you need a versatile kit and want the best drill bit for perspex in mixed jobs, this set gives pragmatic value.
Best Use Cases
| Best for | Why It Works |
|---|---|
| Construction | Good for masonry tasks with occasional acrylic drilling. |
| Outdoor fixtures | Drill through brick and anchoring plates near acrylic covers. |
| General DIY | Reliable for mixed-material household repairs. |

Titanium Coated Serrated Bits 8PK
3–10mm serrated side cutting HSS bits for wood, metal, and plastic

Overview
These 8 titanium-coated serrated HSS bits are made for aggressive cutting in wood, metal, and plastics. The serrated side cuts reduce chatter and can pull chips away from the hole. I use them for thicker acrylic where chip ejection matters. Run slow and steady and you’ll get clean perspex holes without melt.
They are versatile for many materials and resist wear. For perspex projects, they can act as the best drill bit for perspex when you need fast chip removal and stable drilling. Clamp and cool for best results on acrylic.
Advantages
- Serrated cutting aids chip ejection
- Titanium coating lowers friction
- Good for thicker perspex sheets
- Works on multiple materials
- Sturdy and quick cutting when used right
Limitations
- Aggressive cut can score if rushed
- May need deburring for perfect finish
- Can overheat if run too fast on plastic
Our Recommendation
I recommend these serrated bits for builders who work with thicker perspex and need fast chip removal. They can be the best drill bit for perspex when speed and clear chips matter. Use low RPM and clamps to avoid melt and get clean holes.
Best Use Cases
| Best for | Why It Works |
|---|---|
| Thick acrylic panels | Cut through thicker perspex without clogging. |
| Workshop use | Fast cutting ideal for production runs. |
| Mixed materials | Handles wood, metal and plastic with ease. |
Final Verdict
I prefer low-speed HSS twist or single-flute bits as my go-to for perspex. They cut clean with minimal heat when used with light pressure and clamping.
For visible or large holes, diamond or diamond hole saws with water cooling give the smoothest edges. Pick the tool that matches your hole size and clamp for the best drill bit for perspex results.
