How to Choose Router Bits by Material: Wood, MDF, Aluminum, Acrylic

The fastest way to better cuts is to match the bit to the material. Here is a practical material-by-material guide.

Router bits by material: comparison

Why material drives the choice

Abrasive MDF dulls carbide fast, so PCD like the PCD spiral cutter pays off. Acrylic needs chip clearance to avoid melting, so a single-flute 8-12 mm spiral bit works best. Aluminum needs heat-resistant coating and high feed, which is why we offer imported tungsten-steel metal cutters.

Quick rule

Soft and fibrous (wood, MDF) → more flutes for finish; gummy (acrylic, aluminum) → fewer flutes for chip clearance; abrasive (panel) → PCD. Match the shank to your collet and you are set.

Frequently Asked Questions

Q: What router bit is best for wood and MDF?

A: Use TCT spiral bits: up-cut for fast chip evacuation, down-cut for a clean top face, or compression for veneer and laminate. For high-volume MDF, step up to PCD.

Q: Which bit cuts aluminum without melting?

A: Use a single-flute metal-grade cutter with a TiAlN or similar coating, at a high feed and correct speed. See the double-edged metal milling cutter for aluminum and alloys.

Q: What bit should I use for acrylic and PVC?

A: Use a single or double-flute bit at a moderate speed with good chip clearance. The 3.175 mm single-flute bit and 8-12 mm spiral bit are built for acrylic and ABS.

Q: Do I need different bits for plywood vs solid wood?

A: A compression bit handles plywood and laminate cleanly; a standard up/down spiral is fine for solid wood. Match flute and shank to your CNC spindle collet.
