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). Let yourself be captivated by reproducible results and smooth, shiny surfaces! 

Busch AU style carbide burs cut more aggressively than standard carbides. Edges are more precise (making setting easier) and they produce a brighter finish. Available in Round on this page as well as 90° Hart and 70° Hart shaped burs, Cone, and in Twist Drills. 

Busch Round Carbide Burs are available in 21 diameters from 0.30mm to 2.30mm (see drop-down menu below). Packaged 6 to a box, available only in multiples of six. Shanks measure 3/32″ diameter and are marked with a gold band for easy identification. 

Please consult ANSI (American National Standards Institute) for speed recommendations. Made in Germany.
