Kennametal 1291086 Turning Toolholder Rh Neutral Rake

Product Description

The KENNAMETAL 1291086 is a right-hand indexable turning toolholder built for precision metal-turning operations on CNC and manual lathes. Part of the K-Lock series, it features a neutral rake angle of 0 degrees and accepts RC..23 inserts secured by a clamp-style holding method. The steel shank measures 1 inch wide by 1 inch high with an overall length of 6 inches, providing a rigid, stable platform for consistent material removal. Licensed machinists and CNC operators use this holder in production and job-shop environments where repeatable insert indexing and tight tolerances are required.

This toolholder is suited for external turning applications in both production and job-shop settings. The K-Lock clamping system holds RC..23 inserts with an inscribed circle of 0.25 inches, supporting a maximum depth of cut of 0.75 inches. The back-of-bar to cutting edge distance is 1.875 inches, making it compatible with standard tool post and turret setups on lathes sized for a 1 x 1 inch shank. No coolant-through capability is present, so external coolant delivery should be used when thermal management is needed.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before mounting or removing the toolholder from the turret or tool post.
