Kennametal 1796546 Threading Insert KC5010 Carbide 6 Tpi

Product Description

The KENNAMETAL 1796546 is a carbide threading insert designed for cutting Stub Acme thread profiles in both internal and external threading operations. Manufactured to the NAS3L6 geometry and offered in the KC5010 grade, this insert carries a TiAlN finish applied via PVD coating, which improves heat resistance and edge wear during threading at elevated cutting speeds. It is a left-hand insert in the Top Notch series, sized at Insert Size 3 with a cutting tip width of 0.0654 inches and a tip-to-top height of 0.1492 inches. Machinists and CNC operators working in job shop or production environments install this insert into compatible Top Notch threading toolholders.

This insert is suited for Stub Acme thread profiles at 6 TPI on both internal and external workpieces. The left-hand orientation makes it appropriate for reverse-thread applications or left-hand lead screw production. Material grades C3 and C4 indicate suitability for cutting steel, cast iron, and similar ferrous materials. It is commonly used in lathe-based threading operations where consistent thread form and tool life are priorities on production runs or precision component work.

Installation Notes

This insert is installed by machinists on CNC or manual lathes equipped with a compatible Top Notch threading toolholder. Power down and lock out the machine before seating or removing any insert. Ensure the insert pocket is clean and free of chips before installing to maintain proper seating and thread form accuracy. Follow the toolholder manufacturer's clamping torque guidelines and verify thread form with a gauge after the first pass.
