Series 79 HSS Chaterless 6 Flute Countersink

These standard six flute countersinks are designed for economical, general purpose countersinking, chamfering or deburring. Because of the multiple flute design, chip loads are generally smaller and even at maximum speeds, chatter-free machining is possible.

  • Steam homo surface treatment (blackening) to prolong tool life and prevent galling
