Kennametal 1182363 Threading Insert NT1L K68 Carbide

Product Description

The KENNAMETAL 1182363 is a carbide threading insert in the Top Notch series, designed for internal thread cutting operations on CNC lathes and turning centers. Manufactured from K68 uncoated carbide in a bright finish, this left-hand insert produces partial profile 60-degree threads. It covers an internal pitch range of 1.00 to 2.00 mm and 12 to 24 TPI in a single insert, making it a practical choice for shops threading a range of metric and unified pitch specifications. The insert style is NT1L with an insert size of 1, a tip-to-top height of 0.0429 inches, and a corner radius of 0.0031 inches. Installed by machinists and CNC turning technicians, this insert seats into compatible Top Notch toolholders.

This insert is suited for internal threading on both production and job-shop turning operations. The K68 carbide grade and uncoated bright finish are well matched for threading non-ferrous metals, cast iron, and certain steel applications where a coated grade is not required. The left-hand configuration is specified for left-hand thread forms or right-hand threading with a left-hand toolholder setup. Its compact insert size and defined geometry make it appropriate for threading smaller bores and tight internal features on turned components.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque on the clamping screw per the toolholder manufacturer's specification. Inspect the insert pocket and clamping components for wear or debris before seating a new insert to ensure proper support and thread accuracy.
