SN inverted cone burs have an upside-down cone-shaped cutting head that fits dovetailed and inverted slots and holes. They are used to debur and finish holes and make V-shaped cuts and rear-side chamfers. These carbide burs remove sharp edges, unwanted projections, and excess material from machined workpieces.
