Sandvik Coromant 6427355 Cutoff Insert 2.5 Mm Carbide

Product Description

The SANDVIK COROMANT 6427355 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Part of the CoroCut QD series, this insert features a 2.5 mm cutting width (0.0984 inches) and a TiAlN PVD coating for improved wear resistance and tool life in demanding cutting applications. The CF chipbreaker geometry promotes controlled chip formation during grooving and cutoff passes. Manufactured to grade 1125, it is suited for stable, repeatable performance in production environments. Installation and setup are typically handled by machining professionals and CNC tooling technicians.

This insert is used in grooving and parting applications on ferrous and non-ferrous workpieces in both production and job-shop environments. The QD insert style uses a clamp holding method with a neutral hand orientation, making it adaptable to a range of toolholder setups. It is sized for an F insert seat and carries a 7-degree relief angle with a 0.15 mm corner radius. Typical applications include cutoff operations, external grooving, and shallow profile work on turning equipment.

Installation Notes

Installation should be performed by a qualified machining professional or CNC tooling technician. Power down and lock out the machine before seating or removing inserts. Use the appropriate torque wrench and clamping hardware specified for the CoroCut QD toolholder — do not over-tighten the clamp screw. Inspect the insert seat for debris or damage before seating a new insert to ensure accurate positioning and safe operation.
