SM cone burs have a long cone-shaped cutting head with a pointed end that fits into V-shaped slots, countersunk holes, and narrow or tapered openings such as gear teeth. They can access tight spots to debur without changing the shape of surfaces. These carbide burs remove sharp edges, unwanted projections, and excess material from machined workpieces.
