Kennametal 1799562 Threading Insert KC5010 Api Round

Product Description

The KENNAMETAL 1799562 is a carbide threading insert designed for precision thread cutting on internal and external profiles. It features a TiAlN finish applied via PVD coating, which improves wear resistance and extends tool life in demanding threading applications. The insert carries manufacturer grade KC5010 and material grade C3/C4, making it suited for threading operations on a range of workpiece materials. With an included angle of 60 degrees and an internal pitch of 8 TPI, this left-hand insert conforms to the API Round thread standard. It belongs to the Top Notch series and is installed and changed by machinists and tool-crib technicians working on CNC lathes and manual turning centers.

This insert is used in API Round thread cutting applications, primarily in oil and gas component manufacturing and heavy industrial machining environments where API-spec connections are required. The left-hand configuration is specified when thread direction must run opposite to standard right-hand cuts. Both internal and external thread profiles are supported, giving this insert flexibility across coupling, casing, and tubing thread configurations. It is sized as an Insert Size 3 within the Top Notch series toolholder system.

Key Features

Compatibility

Designed for use with Top Notch series threading toolholders that accept Insert Size 3, NDC-style inserts. Confirm toolholder designation and hand orientation before ordering.

Installation Notes

Threading inserts must be seated fully and securely in the Top Notch toolholder pocket before use. Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque wrench for the clamping screw per the toolholder manufacturer's guidelines. Inspect the insert seat and clamping components for wear or debris before each insert change to ensure accurate thread form.
