Kennametal 1114367 Threading Insert 12 Tpi Left Hand Unj

Product Description

The KENNAMETAL 1114367 is a left-hand external threading insert in the Top Notch series, designed for precision thread-cutting operations on CNC lathes and turning centers. Built from carbide with a Titanium Nitride (TiN) finish applied via PVD coating, this insert delivers consistent performance on a range of workpiece materials. It is sized at 3014 and cuts UNJ-standard external threads at 12 TPI with a 60-degree included angle. The corner radius measures 0.013 inches (0.33 mm) and the tip-to-top height is 0.098 inches (2.49 mm). Machinists and CNC programmers working in aerospace, defense, and precision machining environments rely on this insert for controlled thread form accuracy.

This insert is suited for external threading applications on ferrous and non-ferrous workpiece materials falling under material grades C2, C3, and C4. The left-hand orientation makes it the correct choice for reverse-thread or left-hand thread configurations. The Top Notch series toolholder system provides a secure, repeatable seating interface. Typical installations include aerospace fastener profiles and precision-threaded shafts where UNJ thread form compliance is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Seat the insert fully into the Top Notch toolholder pocket and secure the clamping screw to the toolholder manufacturer's specified method before resuming operation. Inspect the insert seating surface and clamping mechanism for wear or debris before each tool change.
