Kennametal 1799486 Threading Insert 11.5 Tpi Internal

Product Description

The KENNAMETAL 1799486 is an indexable threading insert designed for internal threading operations at 11.5 threads per inch (TPI). Carrying the form designation NDC3115VL75 and grade KC5010, this insert is engineered for consistent thread profile accuracy on CNC lathes and turning centers. The KC5010 grade is a KENNAMETAL carbide grade suited for threading a range of workpiece materials where edge retention and controlled wear are essential. Machinists and tool-crib technicians working in production and job-shop environments will recognize this insert as a standard indexable solution for internal thread cutting at the 11.5 TPI pitch.

This threading insert is used in internal threading toolholders configured for indexable inserts of the NDC form. It is applicable in residential and commercial manufacturing environments where precision internal threads are required, including applications on fluid fittings, pipe adapters, hydraulic components, and mechanical assemblies. The 11.5 TPI pitch corresponds to specific thread standards used in specialty fasteners and fluid-system components. It is installed and indexed by machinists and CNC operators during turning operations.

Key Features

• KC5010 carbide grade for wear resistance in threading applications
• NDC3115VL75 form designation for precise thread geometry
• Indexable design allows for quick insert rotation or replacement without re-setup
• Compatible with standard NDC-form internal threading toolholders

Compatibility

Designed as an OEM-style indexable threading insert for use in internal threading toolholders accepting the NDC3115VL75 insert form. No specific compatible model numbers or system families were provided in the product data.

Installation Notes

This insert is installed by qualified machinists or CNC operators. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the insert clamp to the correct seating torque. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
