Kennametal 1152676 Indexable Threading Toolholder

Product Description

The KENNAMETAL 1152676 is an internal indexable threading toolholder designed for right-hand cutting applications on lathes and turning centers. Built from solid carbide, this toolholder accepts LT 11NR series inserts secured by a screw-holding method, providing consistent clamping force and repeatability across threading passes. The shank measures 0.375 inches in both width and height, with a minimum bore diameter of 0.5 inches and an overall length of 6.0 inches (152.40 mm). Coolant-through capability allows cutting fluid to reach the tool tip directly, supporting chip evacuation and extended insert life in demanding threading operations.

This toolholder is suited for internal threading on small-bore workpieces in production turning environments, including job shops and precision machining facilities. The E06 toolholder style and LT threading series designation make it appropriate for threading operations where a compact, solid carbide shank is required to access deep or narrow bores. Machinists working with CNC lathes or manual turning machines performing internal thread cutting will find this holder a direct-fit solution for that application.

Key Features

• Solid carbide construction for rigidity and vibration damping in internal threading
• Coolant-through design directs fluid to the cutting zone for chip control and tool life
• Screw-clamping insert holding method for secure, repeatable LT 11NR insert indexing
• 0.375 inch square shank with 0.5 inch minimum bore diameter for small-bore access
• 6.0 inch overall length with 0.28 inch center-to-cutting-edge offset
• Right-hand cut orientation for standard internal threading passes

Compatibility

Designed to accept LT 11NR series threading inserts as specified by Kennametal for the LT Threading product line. No additional compatible model numbers or system families were stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following standard lathe tooling setup procedures. Ensure the machine spindle is fully stopped and the turret or tool post is de-energized before mounting or removing the toolholder. Use the correct torque driver for the insert clamping screw as specified in the Kennametal LT Threading insert documentation. Verify minimum bore clearance before entering the workpiece to avoid contact between the shank and bore wall.
