Buying Guide

Choosing the best CNC bits for acrylic is key. You want clean cuts every time.

I remember my first project with clear plastic. I used the wrong bit and the edge melted badly. It was a sticky mess that ruined the piece. Then I switched to a single flute bit designed for plastic. The chips flew away and the edge looked like glass.

Flute Count
Look for one flute designs. This allows chips to escape fast. It prevents heat from melting your work.

Bit Material
Choose solid carbide tools. These stay sharp for a long time. They handle high speeds without breaking.

Direction of Cut
Pick up-cut bits for this task. They pull waste up and out. This keeps the path cool and clean.

Shank Size
Match the shank to your collet. A good fit stops the tool from shaking. This ensures a smooth finish on the side.

Sharpness
The edges must be very sharp. Dull tools will crack the acrylic. Sharp tools slice it like butter.

Coating
Avoid thick coatings for this job. A polished finish is much better. It stops plastic from sticking to the metal.
