Kennametal 1113501 Threading Insert K68 Carbide Top Notch

Product Description

The KENNAMETAL 1113501 is an uncoated carbide threading insert designed for precision thread-cutting on both internal and external profiles. Built to the NTF insert style in the Top Notch series, it carries a K68 manufacturer grade and a C3 material grade, making it suitable for threading ferrous and non-ferrous materials at consistent tolerances. The insert generates a partial profile 60-degree thread form and is ground for right-hand cutting. A corner radius of 0.08 mm helps control thread tip geometry. Machinists and toolroom operators working with CNC lathes or manual threading setups will find this insert straightforward to qualify and seat in compatible Top Notch toolholders.

This insert covers a broad pitch range, handling external threads from 0.60 to 1.75 mm pitch (14 to 44 TPI) and internal threads from 1.00 to 2.00 mm pitch (12 to 24 TPI). That range makes it practical for general threading work across both metric and inch-series fastener profiles in a single insert. Typical applications include threading on turned components, pipe fittings, and threaded bosses in a production or job-shop environment. The bright uncoated finish suits applications where coating adhesion or chip welding on softer materials is a concern.

Installation Notes

Threading inserts should be installed by a qualified machinist following the toolholder manufacturer's clamping specifications. Power down and lock out the machine spindle before seating or changing inserts. Inspect the insert pocket and clamping hardware for wear or debris before installation, as a poorly seated insert can deflect under cutting loads and damage the thread form. Follow applicable shop safety procedures and toolholder torque guidelines published by the toolholder manufacturer.
