Kennametal 1096241 Mdjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096241 is a right-hand MDJN-style indexable turning toolholder designed for negative rake insert applications on CNC and manual lathes. Part of the Kenloc series, it accepts DN..43. style inserts held by a clamp and screw mechanism, providing rigid, repeatable insert positioning during external turning operations. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches and a head length of 1.38 inches. The back-of-bar to cutting edge distance is 1 inch. This toolholder is intended for use by machinists and turning professionals in production and job-shop environments.

This toolholder is suited for external turning operations on lathes where a negative rake insert geometry is specified. The MDJN style provides a 3-degree lead angle, making it appropriate for general-purpose turning, facing, and profiling where insert security and consistent depth-of-cut control are priorities. It is a single-use-orientation tool — right-hand only — and does not support coolant-through delivery. Typical applications include carbon steel, alloy steel, and other machinable materials where standard DN..43. inserts are stocked and preferred.

Installation Notes

Installation and tool setup should be performed by a qualified machinist. Secure the toolholder in the turret or tool post per the machine manufacturer's torque and clamping specifications before operation. Ensure the machine spindle is fully stopped and locked out before changing inserts or adjusting the toolholder position. Do not exceed the insert manufacturer's recommended depth of cut or feed rate for the DN..43. insert grade selected.
