Kennametal 1799522 Threading Insert 3040 Ndc KC5010 Carbide

Product Description

The KENNAMETAL 1799522 is a solid carbide threading insert designed for precision thread cutting on API Rotary Shoulder Connections. Manufactured in the NDC style and coated with TiAlN via a PVD process, this insert delivers thermal resistance and wear performance in demanding threading applications. It carries the KC5010 grade designation, rated for C3 and C4 material grades. The insert produces internal and external threads at 5 TPI with a 60-degree included angle. Licensed machinists and tooling specialists install this insert into compatible Top Notch toolholders for high-accuracy thread forming on oil field and industrial components.

This insert is suited for threading operations on API Rotary Shoulder Connection profiles, covering both internal and external thread forms. It is a left-hand insert, making it appropriate for reverse-thread or left-hand-orientation cutting setups. The 3040 insert size fits the Top Notch series toolholder system. Typical applications include oil field tubular goods, drill collars, and rotary shoulder connection machining where API thread standards must be held to close tolerances.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable insert systems. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the toolholder pocket is clean and free of chips or debris before installation to maintain proper seating and thread accuracy. Follow the toolholder manufacturer's recommended clamping procedure for Top Notch style inserts.
