Customer Reviews (4.8 / 5 · 5 reviews)

Lucy ★★★★★

I was able to dial in perfect rabbets on some oak shelving without any chip-out, and the 1/4-inch shank fit my router collet just right. The cut stayed clean even after several passes.

Sebastian V. ★★★★★

The AstraHP coating is the real deal—after a dozen cuts through hardwood, the edge still feels factory sharp. Cuts are silky clean with zero tear-out, and the 1/4" shank fits my trim router perfectly without any wobble.

Elizabeth L. ★★★★★

Took a scrap piece of oak to test it, and the 3/8-inch cutting diameter left a perfectly clean rabbet with no tear-out. The AstraHP coating definitely seems to help it glide through the cut smoother than my old uncoated bit.
