Sandvik Coromant 5737870 Grooving Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5737870 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the ISO designation N151.3-A088-20-4G 235 and belongs to the T-Max Q-Cut series, a platform built for consistent chip control and dimensional accuracy in grooving applications. The insert features a 0.088 inch cutting width, a 4G chip breaker geometry, and a CVD-applied TiCN and TiN coating that provides wear resistance and surface hardness. The neutral hand orientation makes it suitable for straight-in grooving without lateral bias. Manufacturer grade 235 is optimized for stable cutting performance across a range of workpiece materials.

This insert is used in industrial and production turning environments where accurate groove width and controlled chip evacuation are required. It is suited for external grooving and parting on small to medium diameter workpieces. The 4G chip breaker geometry supports reliable chip breaking at moderate feeds and depths. Machinists and CNC operators in metal fabrication, aerospace component production, and general turning shops will find this insert applicable to both light finishing and semi-finishing grooving passes. The multi-use designation indicates suitability across various grooving pass types within its design parameters.

• Multi-use rated for versatility across grooving and parting pass types

Compatibility

Designed for use with SANDVIK COROMANT T-Max Q-Cut series toolholders accepting insert seat size 20 and the N151.3 insert style. Specific toolholder compatibility should be confirmed against the manufacturer catalog using ISO code N151.3-A088-20-4G 235.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC operator following the toolholder manufacturer torque and clamping procedures. Ensure the machine spindle is stopped and all motion has ceased before indexing or replacing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Do not exceed the cutting parameters specified in the manufacturer application data for grade 235 and the 4G geometry.
