Thomas ★★★★★

The AstraHP coating on this bit really helps the plywood edges stay crisp without burning, even on deep passes. Cuts cleanly through birch ply with almost no tearout.

Miles X. ★★★★★

The 19/32-inch actual diameter is spot-on for a snug fit in 5/8 plywood, and the AstraHP coating kept the edges crisp even on a long run of dadoes. Paired with my 1/4-inch collet, it tracked true with zero wobble, which is exactly what I need for repeatable joinery cuts.

Hannah W. ★★★★★

Just finished running it through a test on some Baltic birch, and the cut is glass-smooth with zero chipping on the top laminate. The actual 19/32-inch diameter matched my measurements perfectly, so the dado fit the shelf tight on the first try. Really impressed with how cleanly the AstraHP coating
