Category: Compression CNC Router Bits

This metric 10mm compression spiral is engineered for commercial cabinet shops running metric CAD/CAM programs and cutting sheet goods all day. The cut diameter is ground true to metric—no imperial rounding—so toolpaths, offsets, and part dimensions remain exact from program to part.

The compression geometry delivers clean top and bottom edges in melamine, plywood, and prefinished panels, while the 1/2″ shank provides the rigidity required for nested-based manufacturing and full-sheet passes. AstraHP coating helps manage heat and edge wear in abrasive panel materials, extending tool life and maintaining cut quality over long runs.

This is a CNC-only production tool intended for professional cabinet and furniture workflows.

• Cut Diameter: 10 mm (0.394″)
• Shank Diameter: 1/2″
• Geometry: Compression Spiral
• Coating: AstraHP
• Application: Sheet Goods
• Machine Type: CNC Only

Edward ★★★★★

I've been running this bit in our shop for two weeks straight cutting melamine, and the AstraHP coating still looks like new. The 10mm diameter fits perfectly in our metric tool changer without any collet fuss.

Richard ★★★★★

Finally a true 10mm cut diameter instead of the "close enough" imperial bits I've been fighting for years. Our metric cabinet programs nest tighter now and the edge quality on melamine is clean enough to skip a finishing pass.

Owen ★★★★★

Running 3/4" ply through this 10mm compression spiral all week and the edges are coming off the router with almost no tearout on either face. Being ground true to metric means my tool offsets actually match what the CAD says, which has saved me a ton of guessing.
