Modular System with the Performance of a Solid Carbide End Mill 

The ONLY modular system with the performance of a solid carbide end mill

Duo-Lock is a new revolutionary coupling for solid carbide end milling applications.

This replaceable head design combines a high accuracy in runout and length repeatability
with maximum stability, making it a precise and virtually unbreakable interface.

To adapt Duo-Lock perfectly to your spindle, a vast array of adapters and extensions are available.

  • Standard length extensions with Safe-Lock™, cylindrical and conical.
  • Cut-to-size extensions, cylindrical and conical.
  • Integral adapters with HSK, PSC, CV, and BT back ends.
  • Reconditioning will maximize tool life and your investment.
