Sandvik Coromant 6427477 Cutoff Insert 3mm Corocut Qd

Product Description

The SANDVIK COROMANT 6427477 is a solid carbide cutoff insert designed for parting and grooving operations on CNC turning centers and lathes. Carrying the manufacturer catalog number QD-RG-0300-0502-CM 1125, this insert belongs to the CoroCut QD series and features a 3.00 mm (0.1181 inches) cutting width with a 5-degree right-hand lead angle. The CM chipbreaker geometry and PVD-applied TiCrAlN and TiAlN coating combination are suited for consistent chip control and wear resistance in production turning environments. Machinists and CNC operators working in job shops or production facilities install this insert as a direct replacement in compatible QD-style toolholders.

This insert is intended for cutoff and grooving applications where a 3.00 mm cutting width and right-hand orientation are required. The G insert seat size and clamp-style holding method match standard CoroCut QD toolholder configurations. Typical applications include parting bar stock, grooving external diameters, and light profiling cuts on ferrous and non-ferrous materials in both high-volume production and small-batch turning operations.

Key Features

• 3.00 mm (0.1181 inches) cutting width for precise parting and grooving
• Solid carbide substrate with manufacturer grade 1125 for toughness and edge retention
• PVD-coated with TiCrAlN and TiAlN for heat resistance and extended tool life
• CM chipbreaker geometry for reliable chip evacuation during cutoff operations
• 5-degree right-hand lead angle with 7-degree relief angle for controlled cutting action
• 0.20 mm (0.0079 inches) corner radius for consistent groove geometry

Compatibility

Designed as a replacement insert for CoroCut QD series toolholders accepting G-seat inserts with a 3.00 mm cutting width and right-hand orientation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine in a safe, powered-down or program-stopped state before indexing or replacing inserts. Use the appropriate torque wrench per the toolholder manufacturer clamp specifications and inspect the insert seat for chips or debris before seating the insert. Follow applicable shop safety procedures and the toolholder manufacturer guidelines for proper clamp engagement.
