Nicholas ★★★★★

That AstraHP coating really helps the bit glide through plywood without burning, even on long cuts. The 31/64-inch diameter worked perfectly with my 1/2-inch sheets, giving me clean, tight-fitting dadoes right out of the box.

Riley ★★★★★

My dadoes finally fit snugly without that annoying wiggle room. The AstraHP coating seems to be holding up well after a dozen cuts through hardwood ply, and the 31/64th sizing matches modern sheets perfectly.

Adam Y. ★★★★★

The 31/64-inch undersized cut is spot on for 1/2-inch plywood—no more fighting with chunky fit. The coating kept the edges crisp through a full sheet of dados, and the 1/4-inch shank held steady without any wobble.
