Kennametal 1245571 Indexable Cutoff Blade A2 Double End

Product Description

The KENNAMETAL 1245571 is a double-end neutral indexable cutoff blade designed for parting and grooving operations on CNC lathes and turning centers. Built to the A2BNSN blade style, it measures 19 mm (0.748 inches) in height, 1.8 mm (0.071 inches) in width, and 86 mm (3.386 inches) in overall length. The blade accepts A2 series inserts with a 2.2 mm insert width and uses a self-grip insert holding method for secure, repeatable clamping. Maximum depth of cut reaches 20 mm (0.790 inches), making it suitable for moderate-diameter bar stock cutoff work. Machinists and toolroom technicians working in production turning environments are the primary users.

This blade is intended for use in turning and OD grooving applications where a neutral cutting direction is required. It fits standard A2 Cut-Off series toolholders and blade pockets. The double-end design allows the blade to be flipped when one end wears, extending usable blade life per unit. Typical applications include cutoff operations on steel, stainless steel, cast iron, and non-ferrous materials in both job-shop and production environments. The A2 series is a common platform in CNC turning departments that run high-volume parting cycles.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with indexable tooling systems. Ensure the machine spindle is fully stopped and the turret is in a safe index position before removing or seating the blade. Confirm the blade is fully seated in the pocket and that the insert is properly locked in the self-grip seat before resuming cutting operations. Follow the machine tool manufacturer torque guidelines for any clamping screws on the toolholder body.
