Kennametal 1113025 Threading Insert KC730 16 Tpi

Product Description

The KENNAMETAL 1113025 is a carbide threading insert designed for external thread-cutting operations on CNC lathes and turning centers. Carrying the KC730 manufacturer grade with a PVD-applied Titanium Nitride finish, this insert delivers wear resistance suited to interrupted cuts and varying workpiece materials rated C2 through C4. It cuts at 16 threads per inch on UNJ-standard external threads with a 60-degree included angle. The right-hand NJ insert style seats into Top Notch toolholders. Machinists and CNC operators working in aerospace, defense, and precision manufacturing will find this insert well matched to tight-tolerance threading applications.

This insert is intended for external UNJ threading at 16 TPI, typical in aerospace fastener and fitting applications where the UNJ thread form is specified for fatigue resistance. The Top Notch series indexable system allows rapid insert changes without disturbing toolholder position. The NJ3010R16 geometry and KC730 grade combination handles steel, stainless, and high-temperature alloys within the C2-C4 material grade range. It is sold individually by package quantity, with a minimum order quantity of 5 units.

Key Features

• KC730 carbide grade with PVD Titanium Nitride coating for extended tool life
• 16 TPI external UNJ thread form with 60-degree included angle
• Right-hand cutting orientation, NJ insert style
• Corner radius of 0.0099 inches (0.25 mm) for controlled thread root geometry
• Top Notch series compatibility for fast, repeatable indexing
• C2, C3, and C4 material grade coverage including steel and high-temp alloys

Compatibility

Designed for use with Top Notch series threading toolholders accepting NJ-style inserts with an insert size designation of 3010. Verify toolholder bore and insert seat specifications before installation.

Installation Notes

Threading inserts should be installed by a qualified machinist or CNC tooling technician following the toolholder manufacturer's torque and seating procedures. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Do not run the insert beyond its rated cutting edge condition, as a worn edge on thread-form inserts will produce out-of-tolerance thread geometry.
