Kennametal 1096290 Mvjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096290 is a right-hand MVJN-style indexable turning toolholder built for negative-rake external turning operations on CNC lathes and manual turning centers. Part of the Kenloc series, it features a clamp-and-screw insert-holding method that delivers secure clamping force and repeatable insert indexing. The toolholder accepts VN..43. style inserts with a 0.5-inch inscribed circle diameter. It is designed for use by machinists and tool-and-die professionals performing precision turning in production and job-shop environments.

This toolholder is suited for external turning applications in both production and general-purpose machining environments. The 3-degree lead angle geometry makes it appropriate for straight turning and light facing passes. The steel construction handles the rigidity demands of negative-rake tooling under moderate-to-heavy material removal rates. It is typically installed in 1-inch square shank tool blocks on gang slides, turrets, or quick-change toolpost systems where a right-hand approach path is required.

Installation Notes

Installation should be performed by qualified machinists following machine tool manufacturer torque and clamping guidelines for the specific turret or toolpost. Ensure the machine spindle is fully stopped and the machine is locked out before changing or indexing inserts. Confirm insert seating and clamp screw engagement before returning the machine to operation. Coolant-through supply is not supported on this holder.
