Kennametal 1799513 Threading Insert ND3038L KC5025

Product Description

The KENNAMETAL 1799513 is a carbide threading insert designed for precision thread-cutting operations on API Rotary Shoulder Connections. Offered in the Top Notch series with an ND insert style, this insert carries a TiAlN finish applied via PVD coating process, delivering improved wear resistance and heat tolerance in demanding threading applications. It cuts a 60-degree included angle at 4 TPI and is configured for left-hand threading on both internal and external thread forms. Licensed machinists and CNC lathe operators working in oilfield and energy sector applications will find this insert suited to high-tolerance shoulder connection work.

This insert is intended for use in API Rotary Shoulder Connection threading operations, covering both internal and external thread profiles. The KC5025 grade carbide with TiAlN PVD coating is well-matched to the abrasive and interrupted cutting conditions common in oil country tubular goods (OCTG) and drill collar threading. It fits the Top Notch toolholder system using insert size 3038 and is a left-hand configuration, so correct holder orientation must be confirmed before installation.

Key Features

• TiAlN PVD coating for elevated wear resistance and thermal stability
• KC5025 carbide grade rated for C2 and C6 material grades
• 60-degree included angle at 4 TPI for API Rotary Shoulder Connection profiles
• Left-hand insert orientation for dedicated left-hand threading applications
• Handles both internal and external thread forms from a single insert geometry
• Top Notch series platform for secure, repeatable insert indexing

Compatibility

Designed for use in KENNAMETAL Top Notch series toolholders accepting insert size 3038, configured for API Rotary Shoulder Connection threading with left-hand orientation.

Installation Notes

Threading inserts of this type are installed and indexed by qualified CNC machinists or manual lathe operators following machine-specific toolholder torque and clamping procedures. Confirm the toolholder is rated for left-hand insert geometry before seating this insert. Always bring the machine to a full stop and follow lockout procedures before changing or indexing inserts. Verify insert seating and clamping integrity before resuming cutting operations.
