Sandvik Coromant 6427388 Cutoff Insert Corocut Qd 3mm

Product Description

The SANDVIK COROMANT 6427388 is a solid carbide cutoff insert in the CoroCut QD series, designed for parting and grooving operations on CNC lathes and turning centers. It features a 3.00 mm (0.1181 inch) cutting width, a neutral lead angle, and a TiCrAlN/TiAlN PVD coating applied over a Grade 1125 carbide substrate. The CL chipbreaker geometry promotes controlled chip formation and evacuation during cutoff. With a 0.30 mm corner radius and a 7-degree relief angle, this insert is suited for precision parting on a range of workpiece materials. Machinists and CNC operators install this insert into compatible CoroCut QD toolholders using a clamp-style holding method.

This insert is intended for parting, grooving, and cutoff applications in production and job-shop turning environments. The CoroCut QD platform is commonly used on both manual and CNC turning machines where secure insert clamping and reliable chip control are required. The neutral hand designation makes it suitable for straight radial cutoff passes. The PVD-coated Grade 1125 substrate performs across a range of ferrous and non-ferrous workpiece materials. This is a single-insert package with a minimum order quantity of 10 inserts.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Seat the insert fully in the toolholder pocket before tightening the clamp; do not force or hammer the insert into position. Inspect the insert seat and clamp for wear or debris before each insert change to ensure secure clamping and accurate tool geometry.
