Kennametal 1113504 Threading Insert NT2L K68 Carbide

Product Description

The KENNAMETAL 1113504 is a carbide threading insert in the Top Notch series, designed for cutting both internal and external threads on a lathe or threading toolholder. Built to a partial profile 60-degree thread standard, this insert handles external pitches from 0.70 to 3.00 mm (8 to 36 TPI) and internal pitches from 1.25 to 3.50 mm (7 to 20 TPI). The K68 carbide grade with a bright, uncoated finish is well suited for threading applications where a coated surface is not required or where sharper edge retention on non-ferrous and cast iron materials is the priority. Left-hand orientation is fixed, so verify hand before ordering.

This insert is intended for CNC and manual turning operations in both production and job-shop environments. Its Insert Size 2 profile fits Top Notch compatible toolholders configured for left-hand threading. The broad TPI and pitch range makes it a practical single-insert solution for shops cutting a variety of thread pitches across metric and unified thread forms in one setup. Typical applications include threading on stainless steel, cast iron, and non-ferrous workpieces where an uncoated carbide edge is preferred.

Compatibility

Designed for use with Top Notch series threading toolholders configured for left-hand, Insert Size 2 threading inserts. Verify toolholder hand, insert size, and clamping system compatibility before installation.

Installation Notes

Threading inserts are installed and replaced by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or removing the insert. Use the appropriate torx or clamping key to torque the clamp screw per the toolholder manufacturer's specification. Confirm insert hand matches the direction of the threading pass before initiating a cut.
