Kennametal 1796052 Threading Insert NT3R KC5025 Carbide

Product Description

The KENNAMETAL 1796052 is a carbide threading insert in the NT3R style, designed for precision thread-cutting on both internal and external applications. Coated with TiAlN via a PVD process, this insert carries the KC5025 manufacturer grade and is sized as Insert Size 3. It handles external pitches from 1.25 to 4.00 mm (6 to 20 TPI) and internal pitches from 2.00 to 5.00 mm (5 to 12 TPI), covering a wide range of partial profile 60-degree thread forms. The right-hand cutting geometry and Top Notch series holder interface make it a reliable choice for production threading operations in metal fabrication and machining environments.

This insert is suited for turning centers, CNC lathes, and manual lathes equipped with Top Notch series toolholders. It is applicable to both internal threading operations such as tapped bores and external threading on shafts and fasteners. The partial profile 60-degree thread standard makes it compatible with a broad range of unified and metric thread forms. Machinists and tooling technicians in job shops, OEM production, and maintenance machining operations will find this insert appropriate for ferrous and non-ferrous materials at the C2 and C6 material grades.

Key Features

• TiAlN finish applied via PVD process for extended tool life and heat resistance
• KC5025 grade carbide substrate for wear resistance in threading applications

• Handles internal pitch range of 2.00 to 5.00 mm (5 to 12 TPI)
• Partial profile 60-degree included angle for broad thread form coverage
• Top Notch series interface for secure, repeatable insert seating

Compatibility

Designed for use with Top Notch series toolholders accepting NT3R style inserts in right-hand cutting configurations.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a safe, powered-down or stopped state before insert indexing or replacement. Use the appropriate torque wrench and seating screw specified for Top Notch series holders to avoid insert movement during cutting. Inspect the insert pocket for chips or debris before seating the new insert. Follow the toolholder manufacturer guidelines for recommended cutting parameters when commissioning a new insert.
