Kennametal 1096260 Lh Mdjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096260 is a left-hand MDJN-style indexable turning toolholder designed for negative rake insert geometries. Built on the Kenloc series platform, it accepts DN..43. inserts secured by a clamp and screw holding method. The shank measures 1.25 inches wide by 1.25 inches tall, with an overall length of 6 inches and a head length of 1.24 inches. The back-of-bar to cutting edge distance is 1.5 inches, giving machinists a predictable setup reference. The holder body is steel construction. This toolholder is intended for use on CNC lathes and turning centers where precise insert indexing and rigid clamping are required.

The 1096260 is suited for external turning operations in production machining environments, both job shop and high-volume. The 3-degree lead angle geometry positions the insert for efficient chip formation on ferrous and non-ferrous workpieces. This holder is installed by machinists and CNC turning center operators working with standard square-shank tool posts and turrets. Compatible insert inscribed circle is 0.5 inches (1/2 inch IC), matching the DN..43. insert family designation.

Key Features

• Left-hand cut orientation for specific toolpost and turret configurations
• MDJN style with negative rake for strength and edge durability during interrupted or heavy cuts
• Kenloc clamp-and-screw insert holding method for rigid, repeatable insert seating
• 1.25 x 1.25 inch square shank fits standard lathe tool blocks and VDI-style turrets
• Steel shank construction for rigidity and resistance to deflection
• No coolant-through — suited for external flood or dry cutting applications

Compatibility

Accepts DN..43. series inserts with a 0.5 inch inscribed circle. Complete insert compatibility reference: DN.. 432. Verify insert pocket geometry and screw torque spec against the Kenloc toolholder documentation before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the toolholder from the turret or tool post. Confirm shank seating and clamping torque against the machine tool manufacturer specifications. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert.
