Sandvik Coromant 7861015 Cutoff Insert Corocut Qd

Product Description

The SANDVIK COROMANT 7861015 is a carbide cutoff insert from the CoroCut QD series, designed for parting and grooving operations on CNC lathes and turning centers. It features a 0.0787 inch cutting width with a neutral lead angle, QD-N insert style, and a CM chipbreaker geometry optimized for chip control in a wide range of workpiece materials. The insert carries SANDVIK grade 4425 with a CVD-applied TiCN/Al2O3/TiN multilayer coating, providing wear resistance and thermal stability during high-volume cutoff work. Machinists and CNC operators install these inserts into compatible CoroCut QD toolholders.

This insert is suited for parting and grooving applications on ferrous and non-ferrous metals in production turning environments, both light industrial and heavy manufacturing. The neutral cutting direction and 7-degree relief angle make it adaptable for straight-feed cutoff work. The CM chipbreaker supports consistent chip formation across a range of feed rates. It is sold individually but requires a minimum order of 10 units, making it appropriate for shop floor stocking alongside compatible CoroCut QD holders.

Key Features

• 0.0787 inch cutting width with neutral lead angle for straight parting cuts
• SANDVIK grade 4425 carbide substrate with CVD TiCN/Al2O3/TiN multilayer coating for extended tool life
• CM chipbreaker geometry for reliable chip control in parting and grooving
• 7-degree relief angle reduces flank wear and supports clean cutoff
• 0.0079 inch corner radius for precise groove geometry
• CoroCut QD series insert style QD-N for use with matching QD toolholders

Compatibility

Designed for use with SANDVIK COROMANT CoroCut QD series toolholders accepting QD-NE style inserts. ISO code QD-NE-0200-0002-CM 4425 identifies the exact insert seat and holder configuration required.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is locked before changing inserts. Seat the insert fully into the toolholder pocket and confirm clamping torque per the toolholder manufacturer specifications before resuming cuts. Inspect the insert pocket for debris or wear before each replacement to maintain cutting accuracy.
