Modular End Mills

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.

Part of the First Choice Program

Easy to select, easy to order, easy to apply, exceptional performance. Learn more about First Choice

Intermediate diameters are available upon request as custom solutions.

Reconditioning will maximize tool life and your investment.

Vast array of roughing, finishing, profiling, and chamfering tools, and blanks available. Covering all end milling applications.

Double cone eliminates expensive presetting processes by providing an axial .0004" (10μm) repeatability. Length repeatability from insert tip-to-tip within .002" (50μm).

Intelligent thread ensures stress level to remain below critical values, allowing >25% higher transmittable torque.

3rd contact surface delivers high stiffness and highest accuracy below .0002" (5μm) runout.

With a Duo-Lock™ wrench the tool change becomes easy and can be done in a few seconds.

The Challenge

Improve machining time while reducing cost-per-part.
