I have made 7 desk drawers with this bit. There were 28 sets of tails and grooves (4 corners per box). I used it with a dovetail jig and the drill made very clean and precise cuts. I put a dab of glue in each groove - tap the shanks with a hammer and voila, you have a virtually indestructible box. The tails break and only with great force before each slide. I have no complaints about this bit and I would buy it again and I would try any other bit from this company.
