Sandvik Coromant 6427382 Cutoff Insert 3mm Corocut Qd

Product Description

The SANDVIK COROMANT 6427382 is a solid carbide cutoff and grooving insert engineered for precision parting and grooving operations on CNC lathes and turning centers. It carries a 3.00 mm (0.1181 inch) cutting width and features a neutral hand orientation with a 7-degree relief angle, making it suitable for straight-in parting cuts and shallow grooving profiles. The H13A manufacturer grade designates an uncoated, bright-finish carbide substrate optimized for applications where coating is not required. A 0.10 mm corner radius and CO chipbreaker geometry help control chip flow and reduce built-up edge during interrupted or continuous cuts.

This insert is designed for grooving and parting applications in both light-duty and production turning environments. The QD insert style and G seat size place it within the CoroCut QD system, which uses a clamp-style holding method for secure tool engagement. Typical installations include bar-fed Swiss-style lathes, gang-tool lathes, and conventional CNC turning centers where narrow parting width and chip control are critical. It is sold individually with a minimum order quantity of 10 units per order.

Key Features

• 3.00 mm (0.1181 inch) cutting width with width tolerance of 0.000787 inch for dimensional consistency
• Solid carbide construction in H13A grade — uncoated, bright finish for clean chip flow
• 7-degree relief angle supports positive cutting action in grooving and parting operations
• CO chipbreaker geometry assists chip evacuation during deep or interrupted grooving cuts
• 0.10 mm corner radius reduces stress concentration at the cutting edge
• Clamp-style insert holding method within the CoroCut QD tooling system

Compatibility

Designed for use with SANDVIK COROMANT CoroCut QD series toolholders that accept the G insert seat size with clamp-style holding. This insert is part of the CoroCut QD system.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the machine builder and toolholder manufacturer guidelines. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct clamping screw torque driver specified for the CoroCut QD toolholder — do not overtighten, as carbide inserts are brittle and can fracture under improper clamping load. Verify insert seat and clamping surfaces are clean and free of chips before seating the insert.
