Busch Carbide Twist Drills have a robust 2-blade construction and generously sized chip channels. Made of super hard fine grain carbide these drills are designed to work both on the harder metals associated with carbide tools and on white gold as well. Numerous perfect drill holes can be replicated with the same tool when using a coolant such as our Lube-Stik (816-2460). Twist drills are packaged two to a box, available only in multiples of two. Please consult ANSI (American National Standards Institute) for speed recommendations. Made in Germany.

are available in 12 diameters from 0.50mm to 1.60mm (see drop-down menu above). Shanks measure 3/32″ diameter.
