SGS licensing HAIMER Safe-Lock System

Cutting tool maker SGS Tool Co., Munroe Falls, Ohio, recently signed a licensing agreement with Haimer GmbH, Igenhausen, Germany, for the tool holding company's HAIMER Safe-Lock System, according to a recent news release. SGS Tool, a market leader for solid carbide end mills in North America, has begun offering their high quality cutting tools with the HAIMER Safe-Lock System. The unique Safe-Lock design in cutting tools and tool holders combines high-precision, shrink-fit clamping with a positive form locking mechanism.
