Kennametal 1096307 Mrgn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096307 is a right-hand MRGN-style indexable turning toolholder from the Kenloc series, designed for external turning operations on CNC lathes and manual turning centers. It features a negative 5-degree rake angle and a 15-degree lead angle, which promotes stable cutting and helps direct cutting forces into the workpiece. The toolholder accepts RN..43 series inserts secured by a clamp and screw holding method, providing repeatable insert location and rigid clamping. The steel construction and Kenloc design make it a reliable choice for production turning environments where consistent performance under interrupted or continuous cuts is required.

This toolholder suits general-purpose external turning applications in both job-shop and production settings. The 1-inch by 1-inch square shank fits standard OD turning blocks and quick-change tool posts commonly found on mid-size lathes. It is appropriate for turning ferrous and non-ferrous materials where a negative-rake insert geometry is preferred for its strength and edge durability. Licensed machinists and CNC operators typically select this holder for roughing and semi-finishing passes on steel, cast iron, and similar materials.

Compatibility

Designed to accept RN..43 series round indexable inserts with a 0.5-inch (1/2-inch) inscribed circle. Insert holding is via clamp and screw. Verify insert designation and corner radius against the Kenloc series insert catalog before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank firmly in the toolholder block or quick-change post to the machine manufacturer's recommended clamping torque before cutting. Ensure the machine spindle is fully stopped and the lathe is in an e-stop or locked-out state before changing inserts or adjusting the toolholder. Confirm insert seating and clamp screw engagement before initiating any cutting pass.
