Michael ★★★★★

Down-cut flutes really do keep the top edge clean—I ran it through some plywood and the chip-out was basically nonexistent. The AstraHP coating held up through a solid hour of cutting without any burning or dulling, and the 1/8″ shank fit my router collet snugly.

William I. ★★★★★

The 3/4" cutting length was perfect for my deeper passes in MDF, and the down-cut spiral made a huge difference in preventing chip-out on the top surface. It ran smooth with minimal heat buildup through multiple passes.

Leo D. ★★★★★

Cut several sheets of 3/4" plywood and the down-cut flutes did exactly what they should—no tear-out on the top edge at all. The solid carbide held its edge through the whole job, and the bit came out clean.
