Ball-nosed cylinder burs (SC) debur and finish edges, contours, recesses, bore holes, and round-bottomed slots. They have a barrel-shaped cutting head with a rounded tip and flutes on their sides and their end and are sometimes used as an alternative to ball burs (SD) for shaping applications. Cutting edges are made from carbide, which is a hard material that resists wear and limits heat. Carbide burs attach to rotary power tools such as die grinders, high-speed engravers, and pendant drills.
