Sandvik Coromant 6256906 Grooving Insert 2mm Corocut 1-2

Product Description

The SANDVIK COROMANT 6256906 is a solid carbide grooving insert designed for precise grooving and parting operations on CNC lathes and turning centers. Built to CoroCut 1-2 series specifications, it features a TiAlN coating applied via PVD process, delivering wear resistance and thermal stability in demanding cutting conditions. The insert is left-hand oriented with a 2 mm cutting width, a maximum depth of cut of 5 mm, and a corner radius of 1 mm. An RO chip breaker geometry promotes reliable chip control during interrupted or continuous grooving passes. Licensed machinists and CNC turning specialists are the primary installers of this tooling component.

This insert is suited for external and internal grooving applications on ferrous and non-ferrous workpieces in both production shop and job-shop environments. The positive rake geometry reduces cutting forces, making it appropriate for medium to light grooving passes on precision turned components. It is sold individually per package, with a minimum order quantity of 10 units, consistent with standard indexable tooling procurement practices.

Installation Notes

Installation of indexable grooving inserts should be performed by a qualified machinist with the machine powered off and in a locked-out state per applicable lockout/tagout procedures. Ensure the insert seat and clamping surfaces are clean and free of chips before seating the insert. Use the correct torque wrench per the toolholder manufacturer's clamping specifications — do not over-torque the clamping screw. Verify insert orientation and seating before resuming cutting operations.
