How to Choose the Right CNC Bit for Plastics

Know Your Plastic Type

Identify if you’re working with acrylic, HDPE, PVC, polycarbonate, etc.

Choose Based on Desired Finish

Use O-flute for clean edges, spiral bits for chip evacuation, and compression bits for laminates

Match Bit Specs to Machine Setup

Select bits based on material thickness, tool coating, spindle speed, and feed rate

Why CNC Router Bit Selection Matters

Proper bit selection is essential for high-quality results. The wrong bit can cause melting, edge fraying, or tool damage. At TUOWEI PROTO, we provide bits that match the material and process, delivering better performance, smoother finishes, and longer tool life.

Frequently Asked Questions (FAQs)

What is the best CNC bit for cutting acrylic?

The single-flute O-flute bit offers excellent chip clearance and minimal melting.

Can I use metal CNC bits to cut plastic?

Only if they’re specially designed or coated for plastic. Regular metal bits can cause chipping and melting.

Which bits work best for HDPE?

Straight flute and O-flute bits are best for clog-free, clean cuts.

Do you offer bulk orders of CNC bits?

Yes, TUOWEI PROTO provides wholesale pricing, global delivery, and full customer support.

How can I prevent melting while cutting plastic?

Use sharp, plastic-specific bits, lower RPM, increase feed rate, and ensure good chip evacuation.
