Horn RU108006208TN35 Grooving Insert TN35 Solid Carbide

Product Description

The HORN RU108006208TN35 is a solid carbide grooving insert designed for precision groove-cutting operations on CNC lathes and turning centers. Built to U108 series specifications, this right-hand insert features a 0.062-inch cutting width and a 0.008-inch corner radius, making it well suited for narrow grooving, parting, and recessing applications. The TN35 manufacturer grade delivers balanced hardness and toughness for reliable performance across a range of workpiece materials. The insert is secured via a screw-holding method, providing positive clamping and repeatable edge positioning. Machinists and tooling technicians working in production and job-shop environments typically specify this insert for its dimensional consistency and multi-material capability.

This insert is rated for universal primary workpiece material compatibility, covering material codes K, M, N, P, and S. That range spans cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys, making it a versatile option for shops running varied material grades. It is intended for use exclusively within the U108 toolholder series. The screw-clamping design suits indexed toolholding systems where fast, repeatable insert changes are required. This is a single-use insert; it is not designated as a multi-use tool.

Key Features

• Solid carbide construction in TN35 grade for hardness and wear resistance
• Right-hand cutting orientation
• Screw-holding method for secure, repeatable clamping
• Universal material compatibility across K, M, N, P, and S material codes

Compatibility

Designed for use with HORN U108 series toolholders. Compatible with workpiece material codes K, M, N, P, and S as specified by the manufacturer. Not designated for use outside the U108 toolholder series.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating the insert. Use the correct torque driver for the clamping screw to avoid seat damage or insert fracture - consult the U108 toolholder documentation for the specified torque value. Inspect the insert pocket and seating surface for chips or debris before installation.
