Sandvik Coromant 6427387 Cutoff Insert 3mm Corocut Qd H13A

Product Description

The SANDVIK COROMANT 6427387 is a solid carbide cutoff insert designed for parting and grooving operations in metalworking applications. Part of the CoroCut QD series, this insert features a 3.00 mm cutting width (0.1181 inches) and a neutral lead angle for balanced, straight plunge cuts. The H13A uncoated carbide grade delivers strong edge integrity and heat resistance in demanding cutting conditions. It is held in place by a clamp-style insert holding method and is sized to the G insert seat. A 7-degree relief angle and a 0.20 mm corner radius round out the geometry. This insert is installed by machinists and tooling technicians on CNC lathes and turning centers.

This insert is suited for parting and grooving applications in production and job-shop environments where consistent groove width and clean cutoff are required. The CoroCut QD platform is designed for secure clamping and repeatable indexing. The CM chipbreaker geometry supports effective chip control across a range of workpiece materials. The neutral hand orientation makes it compatible with standard radial parting setups on both conventional and CNC turning equipment.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque tool per the toolholder manufacturer guidelines when tightening the clamp screw. Inspect the insert pocket and clamp for wear or debris before seating the new insert to ensure proper contact and cutting geometry.
