Used this cutter in a router carriage to level split oak. I didn't need much of it, maybe 1/8 inch, maybe 1/4 inch depending on the board change. I didn't even push the drill fast or hard, the slow cuts were barely 1/2 the width of the drill. This cutter was so blunt halfway through the 48" board that it burned all over it. Low quality material. I switched back to the Diablo 3/4" cutter and covered more material faster.
