Sandvik Coromant 6427340 Cutoff Insert 2 Mm Corocut Qd

Product Description

The SANDVIK COROMANT 6427340 is a solid carbide cutoff insert designed for grooving and parting operations on CNC lathes and turning centers. It belongs to the CoroCut QD series and features a 2 mm cutting width, a PVD-applied oxide coating, and a CM chipbreaker geometry engineered to manage chip control in interrupted and continuous cuts. The insert uses a clamp-style holding method with a neutral hand orientation and is assigned manufacturer grade 1145, indicating suitability for a defined range of workpiece materials. A 0.20 mm corner radius reduces stress concentration at the cutting edge. Licensed machinists and CNC operators are the primary installers of this tooling.

This insert is suited for grooving and parting applications in both light and moderate-duty turning operations. The CoroCut QD system is typically applied in production environments where consistent chip evacuation and edge repeatability are required. The E-size insert seat code and neutral hand orientation make this insert adaptable to QD-compatible toolholders used in standard turning setups. Applications include groove profiling, face grooving, and workpiece cutoff on bar-fed or chucked turning equipment.

Key Features

• Solid carbide construction with PVD oxide coating for wear resistance
• 2 mm cutting width with a tight width tolerance of 0.001969 inches
• CM chipbreaker geometry for reliable chip control in grooving and parting
• Neutral hand orientation compatible with standard QD-system clamp-style toolholders
• 0.20 mm corner radius for reduced edge stress and precise groove profiling
• 7-degree relief angle supporting clearance in close-tolerance parting operations

Compatibility

Designed for use with CoroCut QD series clamp-style toolholders accepting an E insert seat size. Verify toolholder seat compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and all stored energy is released before changing inserts. Seat the insert firmly against the pocket locating surfaces before engaging the clamping mechanism, and inspect the seat for chips or debris that could cause improper seating. Do not exceed the cutting parameters recommended by the toolholder manufacturer for this insert style and size.
