Kennametal 1796104 Threading Insert NTP2L KC5025 Carbide

Product Description

The KENNAMETAL 1796104 is a carbide threading insert in the Top Notch series, designed for both internal and external thread cutting operations. It carries the KC5025 manufacturer grade with a PVD-applied TiAlN finish, which provides thermal resistance and edge durability during high-speed threading passes. The insert uses a partial profile 60-degree thread standard and is configured for left-hand threading. External pitch range covers 0.70 to 3.00 mm (8 to 36 TPI), and internal pitch range covers 1.25 to 3.50 mm (7 to 20 TPI). This insert is installed by machinists and CNC operators working in production turning, threading, and thread-repair applications on lathes and turning centers.

This insert fits applications requiring precise thread form on a wide range of pitch sizes in both metric and inch standards. The partial profile 60-degree geometry makes it suitable for unified and metric thread forms across internal bores and external diameters. Typical use cases include production threading on steel and similar materials where the C2 and C6 material grades apply. It is well suited for shops running both conventional and CNC lathes that use Top Notch series toolholders.

Key Features

• KC5025 carbide grade with PVD TiAlN coating for extended tool life in threading operations
• Partial profile 60-degree included angle handles both unified and metric thread forms
• Left-hand insert configuration for left-hand thread cutting or specific toolholder orientations
• Wide pitch range: external 0.70 to 3.00 mm (8 to 36 TPI), internal 1.25 to 3.50 mm (7 to 20 TPI)
• Top Notch series insert style (NTP) for use with compatible Top Notch toolholders
• Corner radius of 0.1 mm (0.004 inches) for fine thread geometry

Compatibility

Designed for use with KENNAMETAL Top Notch series threading toolholders that accept NTP2L style inserts. Compatible with internal and external threading applications on workpieces requiring a partial profile 60-degree thread form across the stated pitch ranges.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and de-energize the machine spindle before seating or replacing the insert. Use the correct Top Notch clamp screw and torque driver as specified by the toolholder manufacturer - do not overtighten by hand. Inspect the insert seat and toolholder pocket for chips or debris before mounting to ensure proper seating and thread accuracy.
