This convenient 12-piece set includes the Busch® drills and burs you need to create precise seats for pavé-style settings.
First, create precision holes of uniform depth in your metal surface using a Busch® pavé twist drill. These drills are specially designed with a shortened cutting area that creates a useful depth guide as you drill the holes. Set includes one each: 0.7mm, 0.8mm, 0.9mm and 1.0mm diameters.
Second, round out the upper part of the seats with one of the round burs, creating a secure mount for the stone girdle. Set includes one each: 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm and 2.3mm diameters.
Finally, use one of the circular saw burs to cut a crisp, clean space between the seats, and then choose the desired saw thickness to cut the notches for the stones. Set includes one each: 2.3 x 0.2mm and 2.3 x 0.3mm.
Made from long-lasting carbide, these burs and drills will maintain their sharp edges longer, and are ideal for use at high speed.
