Sandvik Coromant 6427413 Cutoff Insert 4mm Corocut Qd

Product Description

The SANDVIK COROMANT 6427413 is a solid carbide cutoff insert designed for parting and grooving operations on CNC turning centers and lathes. Part of the CoroCut QD series, this insert features a 4.00 mm cutting width, a neutral lead angle, and a TiAlN plus AlCr2O3 PVD coating that provides heat resistance and extended tool life in demanding machining environments. The chipbreaker style is CO, and the relief angle is 7 degrees, contributing to stable cutting action and reliable chip evacuation. Manufacturer grade 1145 is suited for a range of workpiece materials in precision metal cutting applications. This insert is installed and used by CNC machinists and toolroom technicians.

The 6427413 is designed for use in CoroCut QD toolholders that accept H-seat inserts. It is applied in parting-off and grooving operations on bar stock, turned components, and shaft workpieces in both production and job-shop environments. The neutral hand orientation makes it suitable for standard right-hand tooling setups. A corner radius of 0.20 mm supports controlled surface finish at the cut groove walls. This insert is applicable in aerospace, automotive, and general precision machining where consistent groove width and clean cutoff are required.

Key Features

• Solid carbide construction with PVD-applied TiAlN plus AlCr2O3 coating for wear resistance
• 4.00 mm cutting width with 0.20 mm corner radius for precise groove geometry
• Neutral lead angle and neutral hand for standard toolholder orientation
• 7-degree relief angle for reduced rubbing and stable chip formation
• CO chipbreaker geometry for controlled chip evacuation in parting operations
• Clamp-style insert holding method for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in CoroCut QD series toolholders accepting H-seat inserts. Catalog reference number QD-NH-0400-0002-CO 1145 confirms toolholder and seat size compatibility. Verify toolholder seat size H and clamping method before installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Always power down and lock out the machine before changing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten or use impact tools on the clamp screw. Confirm insert seating is flush and secure before resuming cutting operations.
