Kennametal 1096246 Indexable Turning Toolholder MDJNR165D

Product Description

The KENNAMETAL 1096246 is an indexable turning toolholder configured to the MDJNR165D style, designed for use on CNC and manual lathes in metal-cutting operations. It uses a clamp screw insert-holding method with a negative rake angle, securing DN-style inserts with a 5/8-inch inscribed circle. The 1-inch by 1-inch square shank provides rigid clamping in standard tool blocks and turrets. Overall length is 6 inches, with a head length of 1.47 inches. Manufactured from steel, this holder is part of Kennametal's Kenloc series, which is engineered for consistent insert seating and repeatable tool positioning in turning applications. Installation is handled by machinists and CNC operators in production and job-shop environments.

This toolholder is suited for external turning operations on lathes in both production and job-shop settings. The right-hand configuration is standard for conventional lathe setups where the cutting tool approaches from the right side of the workpiece. It accepts DN-series inserts with a complete insert compatibility designation of DN.. 543. The negative rake geometry is common for interrupted cuts and harder workpiece materials where edge strength is a priority. Coolant-through capability is not included in this holder. It is a single-application tool, not a multi-use or modular design.
