Sandvik Coromant 6397277 Indexable Cutoff Blade Corocut Qd

Product Description

The SANDVIK COROMANT 6397277 is a double-end neutral indexable cutoff blade designed for parting and grooving operations on CNC lathes and turning centers. Built in the Corocut QD series, it measures 1.256 inches (31.90 mm) in blade height, 0.1053 inches (2.68 mm) in blade width, and 5.9055 inches (150 mm) in overall length. The blade uses a clamp-style insert holding method and accepts QD-NG-0300-0002-CM inserts in size code G. Machinists and CNC operators use this blade for precise parting cuts where consistent dimensional accuracy and secure insert retention are required. At 0.27 pounds, it is engineered for rigid tooling setups.

The 6397277 is suited for production turning environments where parting and cutoff operations are performed on a variety of workpiece materials. The double-end neutral configuration supports balanced cutting forces and maximizes blade life by allowing use from both ends. A cutting height of 60.00 mm accommodates moderate-diameter workpiece applications. This blade is typically installed by machinists and CNC setup technicians in job shops, production facilities, and precision machining operations requiring repeatable cutoff performance.

Key Features

• Double-end neutral geometry extends blade service life by providing two usable ends
• Corocut QD series blade style QD-NN2..C..A for rigid, stable insert clamping
• Compatible with QD-NG-0300-0002-CM insert, insert size code G
• Clamp-style insert holding method for secure retention under parting loads
• Blade width of 0.1053 inches (2.68 mm) minimizes material loss at the cutoff point
• Overall length of 5.9055 inches (150 mm) suits standard turning center toolpost setups

Compatibility

Designed for use with compatible insert style QD-NG-0300-0002-CM, insert size code G, within the Corocut QD tooling system. Verify toolholder and insert compatibility against current Corocut QD system documentation before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before changing blades or inserts. Verify that the toolholder bore and clamping components are clean and free of chips before seating the blade. Follow the tooling manufacturer's torque and assembly guidelines for the specific Corocut QD toolholder in use.
