Sandvik Coromant 6397297 Indexable Grooving Blade

Product Description

The SANDVIK COROMANT 6397297 is a left-hand indexable grooving blade designed for precision external grooving and parting operations on CNC lathes and turning centers. Part of the CoroCut QD series, it accepts QD-RL..C..D compatible inserts and is engineered for consistent, repeatable groove geometry in production environments. The blade stands 1.0197 inches high and spans 4.3307 inches in overall length, providing a rigid platform for demanding cut depths up to 1.2992 inches. Machinists and toolroom technicians working on small-diameter workpieces will find the 2.5984-inch maximum workpiece diameter capacity well suited to shaft and component grooving work.

This grooving blade is intended for use in metalworking operations on CNC turning equipment where left-hand cutting direction is required. It fits Cartridge Size 21 toolholding systems and is compatible with Insert Seat Size G. Typical applications include external grooving, undercutting, and parting on ferrous and non-ferrous workpieces up to 2.5984 inches in diameter. The CoroCut QD platform is a recognized system in production turning environments, and this blade integrates directly into that tooling ecosystem. The complete insert compatibility reference for this blade is QD-NG-0300-0002-CM.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians on powered-down CNC turning equipment with all spindle motion fully stopped and machine controls locked out before blade or insert changes. Ensure the cartridge size and insert seat size match the toolholding body prior to assembly. Follow the toolholder manufacturer torque recommendations for clamping screws, and verify blade seating and runout before resuming cuts. Consult applicable shop safety procedures and machine tool documentation throughout the setup process.
