Sofia T. ★★★★★

The AstraHP coating on this bit really does keep it running cool, even when I'm cutting a long string of dadoes. Chips clear nicely through the down-cut design, and the 1/4-inch width is spot on for my plywood shelf projects.

Claire ★★★★★

I was worried about tear-out on 1/4" ply, but this bit left the dado edges perfectly clean. The down-cut spiral really makes a difference.

Leo B. ★★★★★

I was worried about burning the edges of my 1/4-inch plywood, but this bit cut through cleanly. The AstraHP coating really does seem to keep the heat down, and the down-cut design left a smooth, chip-free dado.
