Busch® 231 Carbide Saws

These carbide burs are used for the second step of pave setting in hard metals. After using the Carbide twist drill 4205S to drill the starter holes in the first step of the process, use the appropriate size Carbide round bur 1AU to enlarge the hole. This creates a secure mount for the rondiste of the gem to be set. Cutting in difficult to reach corner areas and also a fine refinishing can be done with the small diameter 0.4 mm bur.
