SC cylinder burs have a barrel-shaped cutting head with a radius end (rounded tip), and they have flutes on their sides and their end. They are used for deburring and finishing newly cut edges, recesses, contours, round-bottomed slots, and other curved surfaces. Also called round-head or ball-nose cylinder burs, they are sometimes used as an alternative to ball burs in shaping applications. Cylinder burs are the most common bur shape. These carbide burs remove sharp edges, unwanted projections, and excess material from machined workpieces.
