Sandvik Coromant 6427338 Cutoff Insert 2 Mm Carbide

Product Description

The SANDVIK COROMANT 6427338 is a solid carbide cutoff and grooving insert from the CoroCut QD series, designed for precision parting and grooving operations on CNC lathes and turning centers. It features a 2.00 mm cutting width (0.0787 inch) with a neutral hand orientation and a 7-degree relief angle, making it suitable for consistent, repeatable cuts in both ferrous and non-ferrous materials. The TiAlN PVD coating in Grade 1105 delivers wear resistance and thermal stability under moderate to high cutting speeds. Installation is performed by licensed machinists and CNC tooling specialists.

This insert is applied in grooving and parting operations on turning machines in production and job-shop environments. It is clamp-held into compatible CoroCut QD toolholders and is suited for both light and medium-duty stock removal. The CM chipbreaker geometry promotes controlled chip evacuation during grooving passes, which is critical for maintaining workpiece surface integrity. Typical applications include OD grooving, face grooving, and full parting of bar stock in both short-run and high-volume production settings.
