Kennametal 1096289 Mvjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096289 is a right-hand MVJN-style indexable turning toolholder built for negative-rake external turning operations on CNC and manual lathes. Manufactured from steel and part of the Kennametal Kenloc series, it features a 1 x 1 inch square shank and an overall length of 6 inches. The holder accepts VN..33. series inserts secured by a combination clamp-and-screw holding method, providing rigid, repeatable insert location under heavy cutting loads. With a 3-degree lead angle and a head length of 1.66 inches, it is suited to general-purpose turning, facing, and profiling where a negative-rake insert geometry delivers strong edge support and extended tool life.

This toolholder is intended for use in production and job-shop turning centers handling ferrous and non-ferrous workpiece materials where stable insert clamping and consistent tool geometry are required. The square shank fits standard lathe tool posts and turret stations sized for 1 x 1 inch tooling. It is a single-use tool configuration, not a multi-use body, making it well suited to dedicated turning stations. Licensed machinists, CNC setup technicians, and tool-crib personnel are the typical end users for this class of tooling.

Key Features

• MVJN toolholder style with right-hand orientation and 3-degree lead angle
• Negative rake geometry supports strong insert edge and heavy-cut stability
• Kenloc clamp-and-screw insert holding method for rigid, repeatable seating
• Steel construction for durability in continuous and interrupted cutting
• 1 x 1 inch shank fits standard turret and tool-post stations
• Back-of-bar to cutting edge distance of 1.25 inches for predictable tool offset setup

Compatibility

Accepts VN..33. series indexable inserts with a 3/8 inch (0.375 inch) inscribed circle. Complete insert compatibility reference: VN.. 332. Verify insert geometry and chipbreaker designation against the Kennametal Kenloc series catalog before ordering inserts.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the turret or tool post is de-energized before mounting or changing the toolholder. Secure the shank squarely in the tool station to the machine manufacturer torque specification found in the machine documentation. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert.
