Kennametal 1796085 Threading Insert NT4L KC5010 Tialn

Product Description

The KENNAMETAL 1796085 is a carbide threading insert designed for precision thread cutting in both internal and external applications. Manufactured in the NT4L style and carrying the KC5010 grade, this insert features a TiAlN finish applied via PVD coating for improved wear resistance and thermal stability at the cutting edge. It cuts a partial profile 60-degree thread form and is sized at insert size 4, with a tip-to-top height of 0.1280 inches (3.25 mm) and a corner radius of 0.0067 inches (0.17 mm). Machining professionals and toolroom technicians use this insert for demanding threading operations on CNC lathes and manual turning machines.

This insert is suited for left-hand threading operations on both internal and external workpiece features. It handles internal pitch ranges from 2.00 to 6.25 mm (4 to 12 TPI) and external pitch ranges from 1.25 to 6.25 mm (4 to 20 TPI), giving it a broad working range across common thread standards. The Top Notch series toolholder system is required for proper seating and clamping. Typical applications include threading operations on steel, cast iron, and other C3 and C4 material grade workpieces in production and job-shop environments.

Compatibility

Designed for use with KENNAMETAL Top Notch series toolholders that accept NT-style threading inserts. Verify toolholder designation and insert pocket geometry before ordering.

Installation Notes

Threading inserts should be seated and clamped by a qualified machinist following the toolholder manufacturer's torque and clamping procedures. Power down and lock out the machine spindle before changing or indexing inserts. Inspect the insert pocket and clamping screw for wear or damage before installation. Do not use damaged or chipped inserts, as edge failure during threading can damage the workpiece and toolholder.
