Customer Reviews (4.6 / 5 · 5 reviews)

Violet K. ★★★★★

The 1/8" corner radius leaves a perfect roundover on the inside edges of my tray pockets, way cleaner than my old straight bit. I pushed it through walnut at 140 IPM taking 1/4" passes and it never once bogged down. The AstraHP coating is still slick after probably 300 linear feet.

Emily ★★★★★

Ran it at 16k RPM and 130 IPM on maple and the cut came out glass smooth with zero burning. The AstraHP coating seems to be holding up way better than my old uncoated bit after the same number of passes.

Robert F. ★★★★★

Ran this at 16,000 RPM and 130 IPM on some walnut and the 1/8" corner radius left almost no sanding to do on my tray pockets. The AstraHP coating is holding up way better than the uncoated bits I used to burn through. Depth per pass at a quarter inch didn't even slow it down.
