I found extra kit is used, it allows me to face montages consolidated by a pin, or simply fix all the boards together (edge to edge, T) with a clean and simple piercings achieve. The only regret is the bit that comes with (9.5 / 3 / 8th) it is not current is approximately 15 alone has cost, and you want to replace the latter by 10mm it falls outside the Gabarie and 9mm that it is very common motion in the guide and to attack the plastic template ass. Morality very good kit but attention has lost or has the drill box.
