Sandvik Coromant 6802748 Cutoff Insert Solid Carbide 3mm

Product Description

The SANDVIK COROMANT 6802748 is a solid carbide cutoff insert from the CoroCut QD series, designed for parting and grooving operations on CNC lathes and turning centers. It carries grade 1125 with a PVD-applied TiCrAlN and TiAlN coating for wear resistance and thermal stability at the cutting edge. The insert has a 3.00 mm cutting width, a QD-N style geometry, and a CM chipbreaker profile suited for controlled chip evacuation in medium to finishing cuts. A neutral hand orientation and a 7-degree relief angle provide clearance and edge stability across a range of workpiece materials. Installation uses a clamp-style holding method compatible with the CoroCut QD toolholder system.

This insert is intended for industrial turning applications including bar stock parting, groove profiling, and face grooving on CNC machining equipment. The CoroCut QD system is commonly used in production environments where consistent chip control and repeatable insert indexing are required. It is typically installed by CNC machinists and toolroom technicians in both job shop and high-volume manufacturing settings. The 0.40 mm corner radius suits general-purpose grooving where a small edge radius is needed to maintain groove geometry and minimize burring.

Key Features

• Grade 1125 solid carbide substrate with PVD coating for extended tool life
• TiCrAlN and TiAlN dual-layer coating provides heat and wear resistance
• CM chipbreaker geometry promotes controlled chip flow in medium and finishing cuts
• 3.00 mm cutting width with 0.40 mm corner radius for precise groove profiling
• Neutral hand insert fits standard CoroCut QD clamp-style toolholders
• 7-degree relief angle reduces rubbing and supports edge stability

Compatibility

Designed for use with CoroCut QD series clamp-style toolholders accepting insert seat size G. Verify toolholder seat size and insert style code QD-N before installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Always power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer to seat the insert securely without over-torquing. Inspect the insert pocket and clamp for wear or debris before seating a new insert.
