Kennametal 1096349 Indexable Turning Toolholder MTJNLS205

Product Description

The KENNAMETAL 1096349 is a left-hand indexable turning toolholder in the MTJNLS205 style, designed for use in CNC and manual turning operations on metal lathes. Part of the Kennametal Kenloc series, it uses a clamp screw insert-holding method to secure negative-rake TN-style inserts with a 5/8-inch inscribed circle. The shank measures 1.25 inches wide by 1.25 inches tall, and the toolholder has an overall length of 6 inches. The head length is 1.44 inches, with a back-of-bar to cutting-edge distance of 1.50 inches. Machining professionals and CNC operators install this holder in standard tool posts and turrets for external turning applications.

This toolholder is suited for external turning on metalworking lathes in both production and job-shop environments. The left-hand orientation makes it appropriate for operations where the tool feeds from left to right along the workpiece. It accepts TN.. 543 series inserts, which are commonly used for turning steel, cast iron, and similar materials. The Kenloc clamping system provides rigid insert location and repeatable edge positioning, which is important in high-volume turning where insert changes must be consistent and fast.

Installation Notes

Installation is performed by machining professionals mounting the holder into a lathe tool post or turret that accepts a 1-1/4-inch square shank. Power off and lock out the machine before securing the toolholder or changing inserts. Use the correct torque driver for the clamp screw to avoid over-tightening, which can damage the insert pocket. Verify tool centerline height before running the first cut.
