Very happy with this cutter. Used it this weekend to cut grooves in some pine boards. I've gradually expanded my knife collection and always looked at Whiteside first. These are quality bits made in the USA. I bought a bit with a 1/4" shank /2" shank bit (#1945). I cut slots in a 5/4 board and wanted the biscuit to be in the center of the board. With the drill set correctly (i.e. /8" or so) I found that the collet got in the way of the workpiece at the height I wanted to cut the slot. I ended up having to get the drill out of the Collet pull another 1/4" or so. I think a 1/2" bit would work better in this situation. But that's not the bit's fault, so I wasn't shooting at the stars.
