Kennametal 1245573 Indexable Cutoff Blade Series A2

Product Description

The KENNAMETAL 1245573 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 32 millimeters high, 2.4 millimeters wide, and 150 millimeters in overall length. The neutral cutting direction suits straight-in plunge cuts without side force bias. It accepts A2 030 series inserts with a 3 millimeter insert width and an insert seat size of 3. The double-end design allows the blade to be flipped when one end reaches wear limits, extending service life. Machinists and CNC operators working in production turning environments rely on this blade for consistent, repeatable cutoff performance.

This cutoff blade is suited for use in production turning applications where precise parting and grooving are required. The 32 millimeter blade height supports a maximum depth of cut of 1.97 inches, making it appropriate for moderate-diameter workpieces. A cutting height of 25.1 millimeters provides clearance geometry for chip evacuation during deep plunge cuts. It is intended for use in toolholders and blade holders compatible with the A2 Cut-Off series, common in industrial turning and bar-fed lathe setups.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder clamping specifications. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing or seating the blade. Confirm the insert is properly seated and the clamping screw is secured before resuming cuts. Inspect the blade seating surface and toolholder pocket for chips or damage before installation.
