Sandvik Coromant 5735870 Indexable Grooving Blade

Product Description

The SANDVIK COROMANT 5735870 is an indexable grooving blade designed for parting and grooving operations on CNC lathes and turning centers. Standing 1.2559 inches high with a blade width of 0.0885 inches, this double-end blade delivers a maximum depth of cut of 2.1654 inches. It accepts N123..A2 series inserts secured by a clamp-style insert holding method, providing consistent repeatability and rigid tool support during high-precision parting operations. Machinists and CNC tooling specialists install this blade into compatible cartridges to achieve clean, controlled cutoff passes on a range of workpiece materials.

This grooving blade is suited for use in neutral cutting direction applications on production turning equipment. It fits into a size 25 cartridge and is cataloged under the Corocut 1-2 series, making it appropriate for shops running standard parting cycles on bar-fed or chucked workpieces. The double-end design extends usable blade life by allowing both ends to be indexed before replacement, which reduces tooling cost per part in high-volume environments.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and locked out before inserting or removing the blade or changing inserts.
