Kennametal 1096092 Lh Mcln Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096092 is a left-hand MCLN-style indexable turning toolholder designed for negative rake insert grades in CNC and manual lathe applications. It accepts CN..43. series inserts secured by a clamp and screw holding method, providing rigid, repeatable insert location during heavy turning passes. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard square-shank holder suited for 1-inch tool blocks and quick-change toolpost systems. Built from steel and produced under the Kenloc series, this holder is installed by machinists and tool-and-die professionals running ferrous and non-ferrous turning operations.

This toolholder fits conventional and CNC lathes equipped with a 1-inch square tool block or compatible toolpost. The 5-degree lead angle geometry promotes controlled chip direction and reduced radial cutting forces during external turning. The negative rake insert orientation suits carbide grades used on cast iron, steel, and hardened alloys. With a head length of 1.2 inches and a back-of-bar to cutting edge dimension of 1.25 inches, the holder positions the cutting edge consistently for repeatable depth-of-cut setup without shimming.

Installation Notes
