Joseph N. ★★★★★

Swapped this into my CNC for a small batch of walnut trim pieces and the 3/16" ball nose left really clean curves with almost no sanding needed. The coating seems to be holding up fine after several hours of routing.

Eli ★★★★★

The AstraHP coating really shows on this bit — after a full afternoon of routing tight radius pockets in oak, the edge still felt sharp with no burn marks. The 3/16" ball nose leaves a clean, smooth floor that needed almost no sanding.

Steven ★★★★★

Ran this 3/16" ball nose through a batch of maple and walnut signs and the edges came off the machine smooth enough to skip most of my sanding. The 1/4" shank seated tight in my collet with zero chatter.
