Sandvik Coromant 5737377 Cutoff Insert 4mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5737377 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Built to the N151.2 insert style, it features a 4 mm cutting width (0.1575 inches) and a neutral lead angle, making it suitable for straight plunge cuts in a wide range of workpiece materials. The insert carries a CVD-applied TiCN/TiN coating and is manufactured in the 235 grade, providing wear resistance and thermal stability during continuous or interrupted turning cuts. A relief angle of 7 degrees and a 0.20 mm corner radius round out the geometry. Installation is performed by licensed machinists or qualified tooling technicians using a clamp-style insert holding method.

This insert is part of the T-Max Q-Cut series, engineered for parting and side turning applications in production and job-shop environments. The 5F chipbreaker geometry is optimized to control chip formation during cutoff operations, reducing the risk of chip buildup in the cutting zone. It fits toolholders and cassettes designed for the N151.2 insert style with a seat size of 40, and is commonly used in both light and medium-duty turning applications on ferrous and non-ferrous materials.

Key Features

• Solid carbide construction in manufacturer grade 235 for consistent tool life
• CVD-applied TiCN/TiN coating for enhanced wear and heat resistance
• 4 mm cutting width with neutral lead angle for straight plunge parting
• 5F chipbreaker for reliable chip control during grooving and cutoff
• 0.20 mm corner radius (0.0079 inches) minimizes stress concentration at cut depth
• Clamp-style holding method ensures secure seating in compatible toolholders

Compatibility

Designed for use with toolholders and cassettes that accept the N151.2 insert style with an insert seat size of 40, as used in the T-Max Q-Cut parting and grooving system.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before accessing the turret or toolholder. Use the appropriate torx or hex key as specified by the toolholder manufacturer to seat and clamp the insert securely. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.
