Unique Conical-Pilot Countersink.

  • Conical pilot seeks and finds the center of the previously drilled hole.
  • Live rubber spring prevents cutting until the pilot is seated and pressure is applied to the workpiece.
  • Cutter extends only after conical pilot has seated.
  • Conical pilot, under spring pressure, eliminates vibration enabling the Counter-Bit to produce chatter-free concentric cuts.
  • A must for every shop! One tool can handle all of your chamfering and countersinking needs.
  • Use on CNC machining centers, robotic arms, manual mills, turret lathes, lathes tailstocks or on drill presses.
  • High speed steel or tungsten carbide blades are easily replaced.
  • Blades are radially relieved with chip breakers.
  • Three models cover the range of holes from 1/4” to 2-1/2” (7mm to 63mm). Straight or Morse tapered shanks. Available with 60°, 82°, 90° and 120° included angles.
