Mia C. ★★★★★

Used this bit on some curly maple today and the AstraHP coating made clean-up a breeze—no gumming up at all. The point cutting tip really does help ease into the cut without grabbing. Just a very clean, consistent roundover every pass.

Edward ★★★★★

I was nervous about tear-out on end grain, but the point cutter on this bit made the first pass smooth as butter. The Astra coating seems like it will hold up well through plenty of use.

Stella ★★★★★

Used this on some walnut today and the AstraHP coating really helped it stay sharp through a dozen passes. The point-cutting design made starting on an inside curve a breeze with zero chipout.
