Horn RU114147800TN35 Grooving Insert TN35 Carbide

Product Description

The HORN RU114147800TN35 is a solid carbide grooving insert in the U114 series, designed for external grooving, recessing, and parting operations on CNC lathes and turning centers. This right-hand insert carries a TN35 manufacturer grade and features a 0.078-inch cutting width with a maximum depth of cut of 0.118 inches. The corner radius measures 0.008 inches. The insert is held in place by a screw-clamp holding method, providing rigid, repeatable positioning in compatible U114 toolholders. Machinists and CNC operators in production and job-shop environments are the primary installers of this insert.

The RU114147800TN35 is suited for grooving operations across a broad range of workpiece materials. The primary workpiece material classification covers universal applications, including cast iron, steel, stainless steel, non-ferrous metals, and heat-resistant superalloys, corresponding to ISO material codes K, M, N, P, and S. It is intended for use in turning centers and CNC lathes running U114-series toolholders where consistent groove width and depth control are required in medium to high-production environments.

Key Features

• Solid carbide construction in TN35 grade for wear resistance across diverse workpiece materials
• 0.078-inch cutting width for narrow, precise grooving and recessing
• Maximum depth of cut of 0.118 inches for grooving and parting applications
• 0.008-inch corner radius reduces stress concentration at groove base
• Screw-clamp holding method ensures rigid, repeatable insert seating
• Right-hand cutting orientation for standard lathe spindle direction

Compatibility

Designed for use with U114-series toolholders that accept the U114 insert style and size code 147800. Specific toolholder compatibility should be verified against the U114 series toolholder documentation before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before changing inserts, the machine must be powered down and the spindle fully stopped per standard lockout/tagout procedures. Use the appropriate Torx or hex key to release and seat the screw clamp; do not overtighten the clamping screw beyond the toolholder manufacturer's specification. Verify insert seating and orientation before returning the machine to service.
