Kennametal 1796083 Threading Insert NT3L KC5010 Carbide

Product Description

The KENNAMETAL 1796083 is a carbide threading insert in the NT3L configuration, designed for cutting both internal and external threads on metal workpieces. It carries the KC5010 grade designation with a TiAlN finish applied via PVD coating, which provides wear resistance and thermal stability during high-speed threading operations. The insert profiles a partial profile 60-degree thread form and is sized for insert size 3, fitting compatible Top Notch series toolholders. It is intended for use by machinists and tool-and-die professionals working with CNC lathes and threading equipment on production and job-shop floors.

This insert handles external pitch ranges from 1.25 to 4.00 mm and 6 to 20 TPI, and internal pitch ranges from 2.00 to 5.00 mm and 5 to 12 TPI. The left-hand cutting geometry makes it appropriate for left-hand thread applications in both ferrous and non-ferrous materials corresponding to material grades C3 and C4. It is sold individually per package, with a minimum order quantity of 5 units, and fits within the KENNAMETAL Top Notch series toolholding platform.

Key Features

• KC5010 carbide grade with PVD-applied TiAlN coating for extended tool life in threading applications

• Left-hand cutting geometry for left-hand thread production on both internal and external features
• Insert size 3 profile fits Top Notch series toolholders for secure, repeatable seating
• Tip-to-top insert height of 0.0980 inches (2.49 mm) with a corner radius of 0.0067 inches (0.17 mm)
• Compatible with material grades C3 and C4, covering a range of common engineering alloys

Compatibility

Designed for use with KENNAMETAL Top Notch series threading toolholders that accept insert size 3 inserts. Thread standard is partial profile 60 degree, covering both internal and external thread forms within the stated pitch ranges.

Installation Notes

Threading inserts should be installed by a qualified machinist following the toolholder manufacturer's clamping torque and seating procedures. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder pocket for chips or debris before seating the new insert to ensure proper contact and prevent premature edge failure. Handle carbide inserts carefully to avoid chipping the cutting edge during installation.
