I've had no luck with this drill but it's excellent for plunge routers. I usually use a fairly low speed on a plunge cutter, although I'm sure this small diameter cutter can rotate much faster. In any case, I get a very clean cut. I use material that is thicker than necessary to allow the plugs to stay in the board when the club is removed. I cut out as many studs as I wanted and then use a tenon saw or similar to pry the studs out of the board. I've tried using both a table saw and a band saw to loosen the connectors, but I've found that a hand saw gives the best result for this. this gives excellent results - the plugs fit perfectly. I have tried other cork cutters but this is by far the best system I have tried.
