Back in 2014, Kennametal announced a technology partnership with Haimer for the development of a modular cutting tool system. Since that time, the company has been busy developing, testing and building its inventory of Duo-Lock, which is said to be the only modular end-mill solution able to compete at solid carbide levels. That means full-width slotting at depths up to 1xD, and side milling at up to 50% radial engagement at 1.5xD, even in stainless steel, titanium and other high temperature alloys.
The first tranche of Duo-Lock products includes the most popular size end-mills in both imperial and metric, as well as an array of adapters, integral shank holders and extensions.
