Sandvik Coromant 5737061 Cutoff Insert 3mm N151.2-300-4E

Product Description

The SANDVIK COROMANT 5737061 is a solid carbide cutoff insert engineered for parting and grooving operations on CNC lathes and turning centers. Cataloged as N151.2-300-4E 4225, it belongs to the T-Max Q-Cut series and features a 3.00 mm cutting width with a neutral hand orientation and a 0-degree lead angle. The insert is manufactured from solid carbide with an MTCVD-applied TiCN/Al2O3/TiN multilayer coating, delivering wear resistance and thermal stability at elevated cutting speeds. A 7-degree relief angle and a 0.30 mm corner radius complete the geometry. Clamped into place during operation, this insert is suited for ferrous and non-ferrous turning applications requiring precise, clean parting cuts.

The 5737061 insert is intended for use in production turning environments including automotive component machining, general-purpose shaft parting, and precision grooving on medium to hard workpiece materials. The T-Max Q-Cut series tooling system accommodates this insert in appropriately sized blade and holder assemblies. The chipbreaker designation 4E is optimized for chip control in medium-depth grooving passes. Typical users include CNC machinists and toolroom technicians operating production or job-shop lathes where repeatable parting performance and insert life are priorities.

Key Features

• Solid carbide substrate with MTCVD TiCN/Al2O3/TiN multilayer coating for extended tool life
• 3.00 mm cutting width with neutral hand and 0-degree lead angle for straight, balanced parting cuts
• 7-degree relief angle reduces rubbing and supports clean edge engagement
• 0.30 mm corner radius for controlled corner geometry on parted workpieces
• 4E chipbreaker geometry promotes chip evacuation in grooving and cutoff operations
• Clamp-held insert style compatible with T-Max Q-Cut blade and holder systems

Compatibility

Designed for use with SANDVIK COROMANT T-Max Q-Cut series blade and holder assemblies accepting insert seat size 30 and insert style N151.2. Consult the toolholder documentation to confirm seat size and clamping compatibility before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified CNC machinist or toolroom technician with the machine spindle fully stopped and all motion axes locked out per facility lockout/tagout procedures. Inspect the insert pocket and clamp for debris or damage before seating the insert. Apply only the clamping torque specified by the toolholder manufacturer for the T-Max Q-Cut system — do not estimate or substitute fastener hardware. Verify insert seating and runout before returning the machine to cutting conditions.
