Kennametal 1096151 Indexable Turning Toolholder Msrnr

Product Description

The KENNAMETAL 1096151 is an MSRNR-style indexable turning toolholder designed for negative-rake external turning operations on CNC and manual lathes. Part of the Kenloc series, it uses a clamp and screw holding method to lock SN-style inserts securely during cut. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard shank size suited for common tool post and turret applications. The steel construction provides rigidity under heavy cutting loads. Licensed machinists and CNC lathe operators working in production or job-shop environments are the typical end users for this toolholder.

This toolholder is suited for right-hand external turning, facing, and profiling operations where a negative-rake SN-style insert is preferred. The MSRNR geometry positions the insert at a specific lead angle appropriate for general-purpose turning. It fits standard 1 inch by 1 inch shank pockets commonly found on manual engine lathes and CNC turning centers. The Kenloc clamping system is designed for consistent insert seating and repeatability across multiple insert changes, reducing setup time in production runs.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret or tool post is locked out before mounting or removing the toolholder. Verify the shank pocket dimensions match the 1 inch by 1 inch shank before seating. Torque the insert clamp screw to the insert manufacturer specification and confirm insert seating before taking a cut.
