Sandvik Coromant 5737073 Cutoff Insert 3mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5737073 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the manufacturer catalog designation N151.2-300-4E 1145 and belongs to the T-Max Q-Cut series. The insert features a 3.00 mm cutting width, a neutral lead angle, and a 7-degree relief angle. The 4E chipbreaker geometry is designed to control chip flow during cutoff and grooving passes. A PVD-applied TiAlN and AlCr2O3 dual-layer coating provides wear resistance and thermal stability. Machinists and CNC operators in production and job-shop environments install this insert for precision cutoff work on a range of workpiece materials.

This insert is suited for parting-off and grooving applications in both production turning and job-shop environments. The T-Max Q-Cut series is designed for use in compatible SANDVIK COROMANT clamp-style toolholders that accept the N151.2 insert style with an insert seat size of 30. The neutral hand orientation makes it adaptable to both left- and right-hand holder configurations. Typical applications include cutoff on steel, stainless, and similar materials where controlled chip evacuation and consistent surface finish at the parting face are required.

Key Features

• Solid carbide construction with PVD-applied TiAlN and AlCr2O3 dual-layer coating for extended tool life
• 3.00 mm cutting width with a 0.30 mm corner radius for consistent groove geometry
• 4E chipbreaker geometry promotes chip control during cutoff and shallow grooving operations
• Neutral lead angle and neutral hand — compatible with both left- and right-hand setups
• 7-degree relief angle reduces flank wear contact and supports clean parting-face finish
• Clamp-style insert holding method ensures secure seating under high radial cutting forces

Compatibility

Designed for use in SANDVIK COROMANT clamp-style toolholders that accept the N151.2 insert style with an insert seat size of 30, within the T-Max Q-Cut series system.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamping hardware specified for the T-Max Q-Cut toolholder to seat the insert securely — do not overtighten by hand. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert.
