Sandvik Coromant 5737066 Cutoff Insert N151.2-300-5E 2135

Product Description

The SANDVIK COROMANT 5737066 is a carbide cutoff insert carrying the catalog designation N151.2-300-5E 2135. It is engineered for parting and grooving operations on CNC lathes and turning centers. The insert is manufactured from solid carbide with a multi-layer MTCVD coating of TiCN/TiN/Al2O3, a combination that delivers thermal resistance and wear performance across a wide range of workpiece materials. The neutral hand orientation suits straight-plunge cutoff applications. A 0.20mm corner radius and the 5E chipbreaker geometry promote controlled chip formation and reduced cutting forces during parting operations. Machinists and CNC operators in metalworking shops are the primary installers of this insert.

This insert belongs to SANDVIK COROMANT product group 151, a series dedicated to parting and grooving. It fits toolholders and blade systems designed around the R151.2 insert style with a size code 30. The 5E chipbreaker is suited for a range of feed rates and material conditions commonly encountered in general turning work, including steel and stainless steel applications. The N151.2-300-5E 2135 designation should be cross-referenced against the toolholder specification to confirm correct seating and clamping before use.

Key Features

• Solid carbide substrate with MTCVD-applied TiCN/TiN/Al2O3 multilayer coating for extended tool life
• Manufacturer grade 2135 optimized for parting and grooving across common workpiece materials
• Neutral insert hand for straight-plunge cutoff operations
• 0.20mm corner radius for controlled edge geometry at the groove floor
• 5E chipbreaker geometry promotes efficient chip evacuation and reduced cutting pressure
• R151.2 insert style, size code 30, for compatibility with corresponding toolholder systems

Compatibility

Designed for use with toolholders and blade systems built around the R151.2 insert style at size code 30. Consult the SANDVIK COROMANT toolholder documentation to confirm correct insert-to-holder fit for your specific setup.

Installation Notes

Indexable insert replacement is performed by qualified CNC machinists or toolroom technicians. Always power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert properly — over-tightening or under-tightening the clamping screw can damage the insert pocket or cause insert movement during cutting. Inspect the insert pocket and clamping components for wear or debris before installing a new insert.
