Adam ★★★★★

Cut a few test grooves in oak ply and the edges came out glass-smooth with zero burning, even at full depth. The AstraHP coating really does keep the bit cooler through a long run, and the 1/4" shank fit my router collet perfectly. Feels like this one will last a good while before needing a sharpen.

Madison N. ★★★★★

I was worried about tear-out on some cheap plywood, but this bit carved crisp, clean V-grooves with zero splintering. The 90-degree angle is spot-on for my sign lettering, and the 1/4-inch shank fit perfectly in my router collet. Definitely getting more projects done now.

Mia ★★★★★

The AstraHP coating really stands out—I've run this through some knotty oak and the grooves stayed glassy smooth with zero burn marks. The 90° point cuts cleanly without any tear-out, even on the cross-grain passes.
