Sandvik Coromant 6397272 Indexable Grooving Blade Neutral

Product Description

The SANDVIK COROMANT 6397272 is an indexable grooving blade designed for parting and grooving operations on CNC lathes and turning centers. Part of the CoroCut QD series, this double-end blade measures 1.0197 inches in blade height and 4.3307 inches in overall length, with a maximum depth of cut of 1.2992 inches. The neutral cutting direction makes it suitable for standard radial grooving and parting applications. It uses a clamp-style insert holding method and accepts QD-NN2..A compatible inserts with an insert seat size of F. Machinists and CNC tooling specialists install this blade as a replacement or new setup component in qualifying CoroCut QD cartridge systems.

This blade is intended for use in turning and parting applications where consistent groove geometry and reliable insert retention are required. It is compatible with cartridge size 21 and accepts the QD-NF-0250-0002-CM insert for precision grooving work. The double-end design maximizes tooling value by providing two usable ends per blade. The narrow blade width of 0.0885 inches allows for tight-tolerance parting cuts and minimal material waste. Typical installations are found in production turning environments running ferrous and non-ferrous materials where the CoroCut QD system is already in use.
