Kennametal 1799413 Threading Insert 24 Tpi KC5010 Carbide

Product Description

The KENNAMETAL 1799413 is a carbide threading insert designed for external thread cutting operations on turning centers and CNC lathes. Manufactured in the NTC3R24E geometry and coated with TiAlN via a PVD process, this insert delivers wear resistance and thermal stability when threading at 24 TPI in UN thread form. The 60-degree included angle matches standard unified thread profiles. The KC5010 grade is suited for demanding threading applications where edge retention and coating adhesion are critical. Licensed machinists and CNC operators specify this insert for production threading on ferrous and non-ferrous workpieces requiring consistent thread form accuracy.

This insert is configured for right-hand, external threading and fits the Top Notch insert system. It is used in toolholders designed for the Top Notch platform on manual lathes and CNC turning equipment in both production shop and job shop environments. Typical applications include threading steel, stainless, and alloy workpieces at 24 TPI to UN thread standards. The insert size is 3 and the material grade is rated C3 and C4, making it appropriate for a range of ferrous machining conditions.

Key Features

• KC5010 carbide grade with PVD-applied TiAlN coating for wear resistance and thermal stability
• 24 TPI external UN thread form with 60-degree included angle
• Right-hand cutting configuration for standard external threading operations
• Top Notch series insert system for secure, repeatable tool seating
• Insert size 3 with a tip-to-top height of 0.148 inches (3.76 mm) and thickness of 0.1949 inches (4.95 mm)
• Corner radius of 0.0053 inches (0.13 mm) for precise thread root definition

Compatibility

Designed for use in Top Notch series toolholders that accept size 3 threading inserts configured for external UN thread applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine powered down and spindle locked before insert changeover. Use the correct Top Notch clamp and torque the clamping screw to the toolholder manufacturer's specification — do not estimate. Verify insert seating and orientation before resuming cutting. Inspect the thread form on the first part using appropriate thread gauges before running production quantities.
