Before ordering
Confirm the required quarter-inch hole and check the bit's actual overall length, flute length and shank against your setup; those dimensions are not supplied here. Use cutting conditions appropriate to the metal and machine. The cobalt alloy does not establish a universal RPM or a guaranteed life multiplier.
