This bit does not work at all as a plunge cutter in solid wood. First, burn wood and set off the shop's fire alarm. The Amana beats are very good, this is the first Amana beat I've had so badly, straight out of the box, brand new.
Compression attachments that have never been used so need to learn. Cut as stated! No breaks, no splinters. You need to cut in one pass so it's best for plywood. At 2000 rpm in one pass, the router tries to jump - even if the cut fails. So if you're using a milling machine instead of a CNC, hold onto it and work slowly. It is sharp and leaves no damage. Worth the money not to ruin the tree.
