Category: Up-Cut CNC Bits

This metric 10mm up cut spiral is engineered for CNC shops running metric CAD/CAM workflows and cutting hardwood panels or solid stock. The cut diameter is ground true to metric—no imperial rounding—so toolpaths and finished part dimensions remain exact from program to part.

The up-cut geometry efficiently evacuates chips upward, making it well-suited for hardwoods, solid lumber, and applications where chip clearance and heat control are critical. A 1/2″ shank provides the rigidity required for stable cutting in production CNC machines, while AstraHP coating helps manage heat and extend edge life during longer runs.

This tool is intended for CNC use only and is built for professional cabinet, furniture, and production workflows.

Made in USA.

Eli I. ★★★★★

I was a little worried about the 10mm diameter being perfect for my metric toolpaths, but it cut through solid oak panels like butter. The AstraHP coating really helps with heat buildup during long runs.

David S. ★★★★★

The metric-ground diameter gave me zero rework on a 10mm dovetail slot—my imperial bits always left a hair of play. Cut through two sheets of walnut-faced ply and the AstraHP coating still looks fresh, no pitch buildup.

Edward L. ★★★★★

The cut on this bit is noticeably cleaner than my old imperial-sized ones, and the coating seems to help it push through cherry without burning. Nice to finally have a true metric option that doesn't require fudging offsets.
