Kennametal 2273015 Lh Ddjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 2273015 is a left-hand DDJN-style indexable turning toolholder designed for negative rake turning operations on CNC lathes and manual turning centers. Part of the Kennametal Kenclamp series, this toolholder accepts DN..33. style inserts held in place by a clamp-style insert holding method. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. A 3-degree lead angle and a head length of 1.25 inches position the cutting edge 1.0 inch back from the bar. The body is machined from steel for rigidity under interrupted cuts and finishing passes alike.

This toolholder is suited for external turning applications in production and job-shop environments. The left-hand orientation makes it appropriate for specific workholding setups where conventional right-hand tooling would cause interference or require reverse spindle rotation. It does not include a coolant-through feature, so flood or mist coolant delivery must be applied externally. Machinists and CNC operators in general machining, aerospace component work, and heavy industrial turning will find this a straightforward OEM-style holder for standard DN..33. grade inserts.

Key Features

• Left-hand DDJN toolholder style for reverse-approach turning setups
• Negative rake geometry suited to heavier feeds and harder workpiece materials
• Kenclamp series clamp-style insert retention for positive insert seating
• Accepts DN..33. inserts with a 0.375-inch inscribed circle
• Steel construction for durability under continuous and interrupted cutting loads
• Coolant-through not required — compatible with standard external coolant delivery

Compatibility

Designed to accept DN..33. style inserts, specifically confirmed compatible with the DN.. 332 insert designation. No additional model or machine compatibility data was provided in the product input.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the toolholder in the turret or tool post to the machine manufacturer's specified clamping torque using appropriate tooling hardware. Power down and lock out the machine before changing inserts or repositioning the holder. Verify insert seating and clamp engagement before resuming spindle operation.
