Kennametal 1796158 Threading Insert NTK3R KC5010 Carbide

Product Description

The KENNAMETAL 1796158 is a carbide threading insert in the Top Notch series, designed for precision thread-cutting operations on both internal and external thread forms. Coated with TiAlN via a PVD process, this right-hand insert handles a partial profile 60-degree thread standard across a wide pitch range. It covers external pitches from 0.60 to 2.50 mm (10 to 44 TPI) and internal pitches from 1.00 to 2.50 mm (9 to 24 TPI). The KC5010 grade and TiAlN finish provide wear resistance in demanding threading applications. The insert weighs approximately 0.02 pounds and is a size 3 Top Notch style insert.

This insert is suited for threading operations on CNC lathes and turning centers where consistent thread form and tool life are required. It is used in both production and job-shop environments for machining steel, stainless, and other materials falling within material grades C3 and C4. Its right-hand orientation and 60-degree included angle make it appropriate for standard unified and metric thread profiles on both internal and external workpieces. Machinists and toolroom technicians working with Top Notch-compatible toolholders will find this insert ready for thread-turning on a broad range of pitch requirements.

Installation Notes

Threading inserts should be installed by a qualified machinist or toolroom technician following the toolholder manufacturer's seating and clamping specifications. Power down and lock out the machine spindle before changing inserts. Ensure the insert seats fully and evenly in the pocket before clamping to avoid chatter or thread-form error. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
