Carbide burs with the EDGE cut have been developed specifically for precise, guided work on edges. They are excellent for chamfering, deburring and edge breaking and rounding, and are mainly used in steel and aluminum construction.
The special bearing design allows the bur to run directly along the edges, without damage to the workpiece. Thus, exact 1/8" radius edge profiles can be created in a single-step operation. Bur cut is general purpose - steel, stainless etc.
