Horn LU114126200TN35 Grooving Insert Solid Carbide TN35

Product Description

The HORN LU114126200TN35 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to Series U114 specifications, this left-hand insert features a 0.062-inch cutting width and a 0.008-inch corner radius, making it suited for tight-tolerance groove profiles. The TN35 grade is a manufacturer-specified carbide grade engineered for broad material compatibility. Installation is via screw-clamp holding, ensuring secure seating in compatible U114 toolholders. Machinists and tool-room professionals install this insert as part of a modular grooving system.

This insert is rated for universal primary workpiece material compatibility, covering material codes K, M, N, P, and S. That range includes cast iron, non-ferrous metals, steel, stainless steel, and high-temperature alloys. It is suited for both light-production and precision grooving applications on CNC turning equipment. The left-hand orientation determines spindle direction and toolholder side selection, so confirm handedness before ordering. The screw-held design supports repeatable insert indexing in production environments.

Compatibility

Designed for use in U114-series screw-clamp grooving toolholders that accept the LU114 insert style. Confirm toolholder hand and insert pocket geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque. Verify insert seating and clearance before resuming cutting operations.
