Kennametal 1096348 Mtjn Lh Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096348 is a left-hand MTJN-style indexable turning toolholder designed for negative rake metal cutting operations on CNC and manual lathes. Built on the Kenloc series platform, it accepts TN..43. (TN.. 432) triangle inserts held in place by a clamp and screw clamping system. The shank measures 1.25 inches wide by 1.25 inches tall, with an overall length of 6 inches. The steel construction provides rigidity under interrupted cuts and high-feed turning passes. Coolant-through capability is not present on this holder. This toolholder is installed by machinists and CNC setup technicians working in production and job-shop turning environments.

The 1096348 is suited for external turning applications where a left-hand approach angle is required, such as turning toward the tailstock or machining features that demand a 3-degree lead angle geometry. The MTJN style positions the insert at a negative rake angle, which is well-matched to carbide inserts in steel, cast iron, and hard alloy turning. Its 1.25 inch square shank fits standard tool post and turret block setups common in medium-duty lathe configurations. The insert inscribed circle of 0.5 inches supports moderate depth-of-cut and feed rate combinations typical in roughing and semi-finishing passes.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the lathe spindle before seating or changing the insert or mounting the toolholder in the turret. Ensure the shank bore or tool post pocket is clean and free of chips before tightening. Follow the lathe and turret manufacturer torque guidelines for tool post screws; do not over-tighten the Kenloc clamp screw beyond the insert manufacturer recommendation.
