Kennametal 1114382 Threading Insert 32 Tpi KC730 Carbide

Product Description

The KENNAMETAL 1114382 is a carbide threading insert designed for external thread cutting applications in precision machining environments. Built in the Top Notch series, this right-hand insert carries the NJK3005R32 style designation and is coated with Titanium Nitride (TiN) via a PVD process, improving surface hardness and wear resistance at the cutting edge. It cuts at 32 TPI with a 60-degree included angle and is sized for UNJ thread standards. The insert measures 0.1409 inches from tip to top and 0.1949 inches in thickness, with a corner radius of 0.0059 inches. It is used by machinists and CNC operators in production threading operations.

This insert is suited for external threading passes on lathes and turning centers. The KC730 grade covers material grades C2, C3, and C4, making it appropriate for threading a range of materials encountered in general machining and aerospace-adjacent work. The NJK insert style and Top Notch series tooling system allow for quick, repeatable indexing. The 32 TPI pitch targets fine-thread applications where precise thread form and finish consistency are critical across production runs.

Key Features

• NJK insert style in the Top Notch series for secure, repeatable seating
• KC730 carbide grade rated for C2, C3, and C4 material groups
• TiN finish applied via PVD process for improved wear resistance
• 32 TPI external threading at 60-degree included angle for UNJ thread standard
• Corner radius of 0.0059 inches for controlled thread root form
• Right-hand cutting geometry for standard lathe and turning center setups

Compatibility

Designed as an OEM-style replacement and standard production insert for Top Notch series threading toolholders accepting NJK-style inserts with size designation 3005.

Installation Notes

Threading inserts of this type are installed and indexed by qualified machinists or CNC operators following the toolholder manufacturer torque and seating guidelines for the Top Notch system. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
