Horn R111476702TN35 Boring Insert TN35 Solid Carbide

Product Description

The HORN R111476702TN35 is a solid carbide boring insert designed for precision internal turning and boring operations. Manufactured to DIN 509 standards, this insert features a Titanium Nitride (TiN) coating in grade TN35, which improves wear resistance and surface finish performance. The right-hand orientation and 47-degree relief angle are suited for tight-tolerance boring work. With a maximum depth of cut of 0.091 inches (2.30 mm), it targets fine finishing passes in a range of metalcutting applications. Licensed machinists and tool-and-die professionals are the primary installers and users of this insert.

This insert is built for universal workpiece material compatibility, covering material codes K, M, N, P, and S - corresponding to cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. It is used in CNC and manual boring bars configured for R111-series inserts. Typical applications include finish boring of bores, undercuts, and relief profiles in precision machined components across general metalworking, aerospace, and die-and-mold environments. The insert is sold individually per package with a minimum order quantity of 2 units.

Compatibility

Designed for use with R111-series boring bars and toolholders accepting this insert style and geometry. Compatible with workpiece material codes K, M, N, P, and S per the manufacturer designation.

Installation Notes

Installation is performed by machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool turret or boring bar is secured before indexing or replacing inserts. Use the appropriate torque wrench and insert screw specified for the toolholder to avoid cracking the carbide substrate. Follow shop-specific toolsetting procedures and verify runout and bore geometry after seating the insert.
