Product Description

The HORN R111132501TN35 is a carbide threading insert designed for internal thread cutting operations. It carries the TN35 manufacturer grade with a coated finish that helps extend cutting life in demanding threading applications. The insert features a partial profile 60-degree thread form and is configured for right-hand cutting. At 0.1100 inches tip to top and 0.1610 inches thick, this insert seats in compatible toolholders used by machinists and tool-and-die professionals for precision internal threading on CNC lathes and manual turning equipment.

This insert is suited for internal threading applications covering a pitch range of 2.50 to 3.00 mm or 9 to 12 TPI, making it versatile across both metric and unified thread standards. It is a right-hand, partial profile 60-degree insert, appropriate for threading steel and similar materials graded C5 and C6. Typical use is in production and job-shop environments where consistent thread form accuracy is required on internal bores.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a powered-down, locked-out state before changing inserts. Seat the insert fully and evenly in the toolholder pocket and secure the clamping screw to the toolholder manufacturer specification. Inspect the insert seat and clamping surfaces for chips or debris before installation, as contamination can affect insert seating and thread form accuracy.
