Sandvik Coromant 6397275 Indexable Cutoff Blade Corocut Qd

Product Description

The SANDVIK COROMANT 6397275 is a double-end, neutral-hand indexable cutoff blade designed for parting and grooving operations on CNC lathes and turning centers. Part of the Corocut QD series, this blade measures 1.02 inches (25.90 mm) high, 0.1053 inches (2.68 mm) wide, and 4.3307 inches (110 mm) in overall length. The double-end configuration allows both ends of the blade to be used, extending service life between blade replacements. A clamp-style insert-holding method secures compatible QD inserts firmly under cutting loads, supporting consistent parting performance at depth.

This blade is suited for precision parting and cutoff work in production turning environments, both light industrial and heavy-cycle applications. The neutral cutting direction makes it compatible with standard right-hand spindle setups without requiring a dedicated hand orientation. Machinists and CNC operators in metalworking shops install this blade in Corocut QD-compatible toolholders for repetitive cutoff, deep grooving, and face grooving operations on bar stock and chucked workpieces.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. The machine spindle must be fully stopped and the turret de-energized before seating or removing the blade from its holder. Secure the blade clamp fasteners with the appropriate hex key to the toolholder manufacturer's specified procedure, and verify insert seating before returning the turret to service. Consult the Corocut QD toolholder documentation for proper blade clamping sequence and insert indexing procedure.
