Kennametal 1096243 Mdjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096243 is a right-hand MDJN-style indexable turning toolholder built for negative-rake insert applications on CNC lathes and manual turning centers. Manufactured in the Kenloc series, it features a 1 inch x 1 inch square shank and an overall length of 6 inches, making it a standard fit for most production turning setups. The toolholder accepts DN..33. style inserts with a 3/8 inch inscribed circle and uses a clamp-and-screw insert holding method for secure, repeatable positioning under heavy cutting loads. At 1.687 pounds, it is constructed from steel for rigidity and long service life.

This toolholder is suited for general-purpose and production turning operations in metalworking environments, including OD turning and profiling on ferrous and non-ferrous materials. The MDJN style provides a 3-degree lead angle, which promotes smooth entry and reduces radial cutting forces. It is a tool used by machinists, CNC programmers, and toolroom technicians in both job-shop and high-volume manufacturing settings. Coolant-through capability is not included in this configuration.

Key Features

• Right-hand cutting orientation for standard OD turning operations
• Negative-rake geometry for increased insert strength and edge durability
• Clamp and screw insert holding method for secure, repeatable insert seating
• Accepts DN..33. inserts with a 3/8 inch (0.375 inch) inscribed circle
• Kenloc series construction from steel for rigidity under interrupted cuts
• 1 inch x 1 inch square shank with 6 inch overall length for broad machine compatibility

Compatibility

Designed for use with DN..33. style indexable inserts (complete insert compatibility: DN.. 332). Verify insert pocket geometry and shank clearance against machine specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank in the turret or tool block to the machine manufacturer's specified clamping torque using calibrated tooling. Power down and lock out the machine before changing inserts or repositioning the toolholder. Inspect the insert pocket and clamping screw for wear or damage each time an insert is indexed.
