Kennametal 1878103 Indexable Cutoff Blade A2 Cut-off

Product Description

The KENNAMETAL 1878103 is a single-end, right-hand indexable cutoff blade designed for parting and grooving operations on CNC lathes and turning centers. The blade measures 32 mm high, 8 mm wide, and 125 mm in overall length, accepting a 3 mm wide insert in an A2 030-style seat. The self-grip insert holding method locks the insert securely under cutting load without additional fasteners, reducing setup time and maintaining repeatable positioning. This blade is used by machinists and CNC operators working with bar stock and turned components where clean, precise parting cuts are required.

The 1878103 is suited for production turning environments where consistent cutoff performance is needed across moderate to high volumes. With a maximum workpiece diameter of 2.598 inches and a maximum depth of cut of 1.299 inches, it handles typical bar-fed turning applications in both job shop and production settings. The A2BNC blade style is part of Kennametal's A2 Cut-Off series, a well-established platform among toolroom and production lathe operators.

• 32 mm blade height and 125 mm overall length provide rigidity in typical turret toolholders
• 3 mm insert width produces a narrow kerf, reducing material loss per cutoff
• Maximum depth of cut of 33 mm supports workpieces up to 2.598 inches in diameter
• A2 Cut-Off series platform with broad insert grade and geometry availability

Compatibility

Designed for use with A2 030-style indexable cutoff inserts in the A2 Cut-Off series. Insert seat size 3 accepts inserts with a 3 mm minimum insert width. Confirm toolholder shank compatibility and turret pocket dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine powered down and in a locked-out, tagged-out state. Secure the blade firmly in the toolholder to the manufacturer-specified clamping method before inserting the cutting insert. Verify blade height alignment to centerline before running the first part. Inspect the self-grip pocket for wear or debris before seating a new insert.
