Kennametal 1878083 Cutoff Blade Tool Block A2TEN 52mm

Product Description

The KENNAMETAL 1878083 is an indexable cutoff blade tool block designed for parting and grooving operations on CNC lathes and turning centers. Built to Style A2TEN in the A2 Cut-Off series, this block accepts blades with a 52mm compatible blade height and mounts via a 1.5-inch square shank. The overall length measures 5.32 inches and the overall height is 3.15 inches, making it a solid, rigid platform for interrupted cuts and deep grooving work. Machinist and toolroom technicians working on production turning applications rely on this block for repeatable insert indexing and consistent cut-off performance. The unit weighs 6.26 pounds.

This tool block is suited for use on manual and CNC turning machines in production and job-shop environments where consistent parting and grooving operations are required. The A2TEN style configuration accommodates a reversible blade orientation, allowing the block to be repositioned to serve both left-hand and right-hand setups without purchasing a separate holder. It is appropriate for ferrous and non-ferrous material cut-off work where a rigid, repeatable tooling platform is needed at the turret or tool post.

• Reversible design allows neutral cutting direction setups in both left-hand and right-hand orientations
• Overall length of 5.32 inches and overall height of 3.15 inches for compact turret fitment
• Overall width of 2.32 inches supports stable blade clamping across the full blade height

Compatibility

Designed for use with indexable cutoff blades with a 52mm compatible blade height in the A2 Cut-Off series. Fits CNC and manual turning machines with tool posts or turrets accepting a 1.5-inch by 1.5-inch square shank holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine fully powered down, spindle stopped, and all motion axes locked out per your facility lockout/tagout procedure. Seat the shank fully into the turret pocket or tool post and verify the block is clamped square before torquing fasteners. Confirm blade and insert seating before taking any cut, and verify proper blade height alignment to centerline for the specific workpiece diameter.
