William J. ★★★★★

This bit cut through some dense walnut like butter, leaving a super clean edge that barely needed sanding. The coating seems to be holding up well even after several hours of carving.

Sophia N. ★★★★☆

I was cutting some oak for a sign and this bit stayed sharp through the whole job. The up-cut design clears chips well, though I did notice a little more tear-out on the bottom edge than I'd like.

Isabella I. ★★★★☆

The AstraHP coating really does its job—I've run it through oak and some light aluminum, and the flutes still look fresh after several hours of carving. Took a star off only because the price stings a bit more than I'd like for a single bit, but the clean chip evacuation makes up for it.
