Applications

The SSKCR/L boring bar is ideally suited for internal longitudinal turning on both CNC and conventional lathes. Thanks to its streamlined shank geometry, it provides excellent accessibility for machining deep, narrow bores and complex internal contours.

It is geared towards professional use in mechanical engineering, contract manufacturing, and toolmaking. The system creates favorable conditions for the economical machining of various workpiece materials when paired with suitable SC.. indexable inserts.

Special features

The straightforward screw clamping system supports efficient workflows by enabling fast and accurately positioned insert changes. By omitting an internal coolant channel, the structural integrity of the steel shank is preserved, providing a highly rigid solution for dry machining or externally cooled turning processes.
