Sandvik Coromant 6802761 Cutoff Insert 4mm Corocut Qd

Product Description

The SANDVIK COROMANT 6802761 is a QD-style cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Built from solid carbide with a PVD-applied TiCrAlN and TiAlN coating, this insert delivers wear resistance and edge stability in demanding cutoff applications. It features a 4 mm cutting width, a 0.40 mm corner radius, and a 7-degree relief angle. The CM chipbreaker geometry is engineered for controlled chip formation and efficient chip evacuation during cutoff passes. This insert is installed by CNC machinists and turning specialists working in production and job-shop environments.

This insert fits the CoroCut QD system, which is used for cutoff and deep grooving on bar stock and tubular workpieces in both light and medium-duty turning applications. The QD-N insert style with H seat size is suited for neutral-hand installations. Typical applications include parting off finished components on Swiss-type and conventional CNC turning centers where consistent cut-off width and chip control are critical to cycle time and surface finish. Minimum order quantity is 10 inserts; each package contains 1 insert.

Key Features

• Solid carbide construction with PVD coating process for extended tool life
• TiCrAlN and TiAlN dual-layer coating provides thermal and abrasion resistance
• 4 mm cutting width with 0.40 mm corner radius for precise groove and parting geometry
• CM chipbreaker for reliable chip control in cutoff operations
• 7-degree relief angle reduces rubbing and supports clean edge engagement
• Clamp-style insert holding for secure, repeatable seating in QD toolholders

Compatibility

Designed for use in the SANDVIK COROMANT CoroCut QD toolholder system, requiring an H insert seat size and compatible with QD-N style clamp holders.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. The machine spindle must be stopped and all axes locked before changing inserts. Use appropriate insert seating tools to fully engage the clamp and seat the insert correctly in the holder pocket — improper seating can cause insert breakage or dimensional inaccuracy. Inspect the insert pocket and clamping components for wear or debris before each insert change.
