Kennametal 1114625 Threading Insert K68 Carbide Top Notch

Product Description

The KENNAMETAL 1114625 is a carbide threading insert designed for precision thread cutting on both internal and external workpieces. Manufactured in the K68 grade with an uncoated bright finish, this insert runs in the Top Notch series and follows a partial profile 60-degree thread standard. It handles external pitches from 0.60 to 2.50 mm (10 to 44 TPI) and internal pitches from 1.00 to 2.50 mm (9 to 24 TPI), making it a versatile single insert for a range of thread forms. Right-hand cutting orientation and a 0.08 mm corner radius support consistent thread geometry across production and maintenance turning operations.

This insert is suited for use on CNC lathes and manual turning centers in machine shops, production facilities, and maintenance environments. It is a fit for operators threading ferrous and non-ferrous materials where a C3 material grade carbide is appropriate. The NTK3R insert style seats into compatible Top Notch toolholders. Machinists and tool-and-die professionals working with metric and unified thread forms will find this insert covers a broad pitch range from a single pocket.
