Busch® Fig. 1AU 0.30mm Round Carbide Burs (Pkg. of 6)

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. 

Busch Round Carbide Burs are available in many different diameters so you're sure to have the size you need. Packaged 6 to a box. Shanks measure 3/32" diameter and are marked with a gold band for easy identification.
