Sandvik Coromant 6256904 Grooving Insert 2mm Corocut 1-2

Product Description

The SANDVIK COROMANT 6256904 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding cut conditions. The insert delivers a 2.00 mm cutting width and a maximum depth of cut of 5.00 mm, with a positive rake geometry and a 1.00 mm corner radius. It is sized for right-hand cutting applications and is intended for professional machinists and tooling technicians working in production turning environments.

This insert fits the CoroCut 1-2 series tooling system and is suited for grooving and parting on a range of workpiece materials including steel, stainless steel, and cast iron. The RO chip breaker geometry is designed to manage chip flow in shallow to medium-depth grooving passes. Typical applications include external grooving on shaft components, ring grooves, and undercut profiles in both job-shop and high-volume production settings. The insert seat size is H and the ISO code is R123H1-0200-RO 1125.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool turret is de-energized before seating or removing inserts. Use the appropriate torx or clamping key specified for the CoroCut 1-2 toolholder to secure the insert; do not over-torque the clamping screw. Inspect the insert seat for debris or damage before mounting to ensure proper seating and repeatability.
