Kyocera S08X-STLCR09-10A Internal Turning Boring Bar – THC11836

The Kyocera S08X-STLCR09-10A internal turning toolholder is a high-precision boring bar designed for internal machining operations such as boring, internal facing, and profiling. Its compact 8 mm cylindrical shank allows access to small bore diameters, making it ideal for precision work in confined machining environments.

Designed for use with positive triangular inserts, this holder provides smooth cutting action with reduced cutting forces, improving surface finish and tool life. The right-hand configuration and optimised geometry ensure efficient chip evacuation and stable machining, while the rigid steel construction minimises vibration and enhances accuracy during operation.
