Ball Lock Features & Benefits

Patented Locking Technology

Inside the shank are 3 balls that expand into a tapered groove in the receiver bushing. This action draws the plates together. The locking balls are activated by turning a setscrew in the head of the shank, which pushes a 4th ball to evenly distribute the clamping forces between the 3 locking balls. No more dowel pins or cap screws, and no need to search around for a hex wrench to remove Ball Lock® shanks.


  • Incredibly FAST setups and changeover
  • Powerfully strong holding forces
  • Combines locking and locating in the same motion
  • Eliminates the need for indicating on CNC machines
  • Repeatability of +/-0.0005” (+/-0.013mm) or better
