Kennametal 1245557 Indexable Cutoff Blade A2 Cut-off

Product Description

The KENNAMETAL 1245557 is a double-end, neutral-cutting indexable cutoff blade designed for parting and grooving operations on CNC lathes and turning centers. Built to the A2BNSN blade style in the A2 Cut-Off series, it measures 32 millimeters in height, 5.4 millimeters in width, and 150 millimeters in overall length. The blade accepts A2 060-style inserts at a 6 millimeter insert width and delivers a maximum depth of cut of 60 millimeters. A self-grip insert holding method eliminates the need for a clamping wedge, simplifying insert changes. This blade is intended for use by machinists and toolroom technicians working in production or job-shop turning environments.

The 1245557 is suited for parting stock and cutting grooves in bar-fed or chucked workpieces on manual and CNC lathes. The double-end configuration allows the blade to be flipped when one end shows wear, extending service life before replacement. The neutral cutting direction makes it appropriate for standard right-hand spindle setups. A cutting height of 25 millimeters and a maximum depth of cut of 60 millimeters cover a wide range of bar diameters and part geometries encountered in general machining work.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the blade in the appropriate A2 series blade holder to the holder manufacturer's specified clamping torque before engaging the spindle. Ensure the machine is fully powered down and the spindle is locked before indexing or replacing inserts. Follow the machine manufacturer's setup procedures and applicable shop safety standards when setting tool height and confirming runout before making the first cut.
