Kennametal 1796141 Threading Insert NTF3L KC5010 Carbide

Product Description

The KENNAMETAL 1796141 is a left-hand carbide threading insert in the Top Notch series, designed for partial profile 60-degree thread cutting on both internal and external applications. Coated with TiAlN via a PVD process, the KC5010 grade insert delivers wear resistance and thermal stability during threading operations on a range of workpiece materials rated at material grades C3 and C4. The insert measures 0.1949 inches thick and carries a corner radius of 0.0031 inches, making it suited for fine, controlled thread forms across a wide pitch range. Machinists and CNC lathe operators working in metalworking and toolroom environments will find this insert a reliable fit for precision threading tasks.

This insert is intended for use in Top Notch series threading toolholders configured for left-hand cutting. It covers an external pitch range of 0.60 to 2.50 mm and 10 to 44 TPI, and an internal pitch range of 1.00 to 2.50 mm and 9 to 24 TPI. Typical applications include threading on lathes in production and job shop settings where both internal and external 60-degree partial profile threads are required. The TiAlN coating makes it well suited for dry or semi-dry cutting conditions on ferrous and hardened materials.

Installation Notes

Threading inserts should be installed by a qualified machinist or CNC operator following the toolholder manufacturer's seating and clamping procedure. Power down and lock out the machine spindle before changing inserts. Ensure the insert seats fully and evenly in the pocket before securing the clamping mechanism. Do not exceed the toolholder's rated depth of cut or feed rate for the pitch being cut.
