Duo-Lock™ - The next Level of Modular Endmilling.

Advanced Materials Require Advanced Manufacturing.

The continuing development of high-strength, lightweight materials such as titanium alloys, Inconel, and new aluminium alloys are eagerly sought by manufacturers in many industries, including aerospace and defense, energy, and transportation. These new materials present significant machining challenges in themselves. Add the competitive pressures in these global industries, and finding advanced manufacturing solutions becomes a top priority.

Duo-Lock™ - Pioneering Technology. Virtually unbreakable.

Duo-Lock Delivery Program

For the first time, a modular milling system can achieve the similar high performance of the latest generation solid carbide endmill. To deliver groundbreaking joint technology, Duo-Lock™ combines the innovative histories of two leaders in the world of manufacturing—HAIMER and Kennametal.

Duo-Lock™ maximizes a carbide tool’s full potential with productivity gains in both roughing and finishing. It provides high load capacity and rigidity when machining at high metal removal rates. When combined with high-performance cutting tools, Duo-Lock™ provides more than double the metal removal rate in common milling applications.

The Duo-Lock™ Technology

Duo-Lock double cone

The Duo-Lock™ technology addresses the issue of the increasing cost of carbide by delivering a modular interface for cutting tool heads. Duo-Lock™ provides maximum stability and load capacity through a proprietary thread design with a double cone bond. The results are unmatched precision and productivity, with a connection that is virtually unbreakable in the most demanding applications.

Duo-Lock™ milling heads

HAIMER Duo-Lock milling head

A variety of the newest milling geometries have become available with the new HAIMER Duo-Lock™. The high-precision and extremely stable Duo-Lock™ interface allows the use of the full potential of the milling geometries and achieves the maximum cutting depths at the same time. The heads can be replaced while tool is on the spindle with high dimensional repeatability.

Duo-Lock™ Shank Extentions

Duo-Lock™ Shank Extention

 

With the new shaft extensions from the Duo-Lock™ series, a universal solution for almost all processing cases is at your disposal:

  • Complete true running accuracy
  • The cost-effective way to process special solutions
  • Universally applicable due to the different tapered geometries and lengths
  • Available with Safe-Lock™ anti-pullout to take advantage of long reach and aggressive cuts.

Duo-Lock™ Tool Holders
