Reliable tool for professional threading operations
The internal threading tool holder SIR impresses with its robust construction and the well-thought-out integration of a cooling hole. This right-hand holder system is specifically designed for internal threading operations and offers high reliability in daily CNC use. The use of a secure screw clamping mechanism ensures a firm grip on the inserts (11/16/22 IR), which in turn supports machining quality across various workpiece contours. Thanks to the targeted internal cooling, workflows are noticeably optimized through improved chip evacuation and cooling of the contact zone.
