CNC Router Bit for Wood and Plastic

This single-flute carbide mill cutter is designed for CNC machinery and handles acrylic, PVC, density board and wood board. The up-down compound spiral geometry produces clean edges on both faces during compression cutting. It suits workshops needing precise profiling on sheet materials.

Replaces Worn Single-Flute Bits

The tool replaces a dull or damaged compression router bit when edge quality drops on double-sided boards. The jump is worth it when tear-out appears on the top or bottom surface of laminated panels. A fresh cutter restores finish quality without changing feed rates.

Check Shank Fit and Material Suitability

Verify that your CNC collet or holder accepts the 6 mm shank before ordering. Confirm the workpiece thickness does not exceed the 22 mm cutting length. The bit is rated for industrial use only and must not be operated by anyone under 18 years old.
