Horn R111081501TN35 Threading Insert Carbide TN35

Product Description

The HORN R111081501TN35 is a carbide threading insert designed for internal thread cutting operations. It features an included angle of 60 degrees and is finished with a Titanium Nitride (TN35) coating, which improves surface hardness and extends cutting tool life in demanding threading applications. This insert covers an external pitch range of 12 to 20 TPI and an internal pitch range of 0.5 to 1.75 mm, conforming to ISO thread standards. It is used by machinists and tooling technicians working with CNC lathes, manual lathes, and threading toolholders in production and job-shop environments.

This threading insert is suited for internal thread forming on a range of workpiece materials where a 60-degree ISO thread profile is required. The TN35 grade carbide construction and Titanium Nitride coating make it appropriate for both ferrous and non-ferrous threading at moderate to high cutting speeds. Typical applications include threading bores in parts requiring ISO-standard internal threads across light manufacturing and precision machining operations. This insert is sold individually per package, with a minimum order quantity of 2 units.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the insert clamp to the correct seating torque without overtightening. Inspect the insert pocket and clamp for wear or debris before seating the new insert to ensure proper contact and cutting geometry.
