Busch Burs - Twist Drills #077 - Size 0.50 up to 1.90 mm
Carbide burs and drills are known for their particular hardness and the resultant tool life, as well as their cutting capacity. These advantageous properties now also make it possible to economically process materials, which are very hard and difficult to cut (such as platinum, white gold, titanium, and steel).
Cut more aggressively than standard carbides. Edges are more precise (making drilling and setting easier) and they produce a brighter finish. Shanks measure 3/32" diameter. Price per pack of 6.
