Sandvik Coromant 5737370 Cutoff Insert 4mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5737370 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Carrying the N151.2-400-5E 4225 catalog designation, this insert features a 4.00 mm cutting width and a neutral lead angle, making it suitable for straight plunge cutting applications. The manufacturer grade 4225 substrate is finished with an MTCVD-applied TiCN/Al2O3/TiN multilayer coating, which provides wear resistance and thermal stability during high-speed parting. Installed by machinists and CNC technicians, this insert fits the T-Max Q-Cut tooling system using a clamp-style holding method.

This insert is intended for use in T-Max Q-Cut parting and grooving systems in production turning environments. The neutral hand and zero-degree lead angle allow the insert to be used in both conventional and Swiss-style turning setups where a direct radial plunge is required. The 5E chipbreaker geometry is optimized for chip control in medium to finishing cuts. Typical applications include bar stock parting, groove profiling, and face grooving on ferrous and non-ferrous workpieces in light to medium-duty operations.

Key Features

• 4.00 mm cutting width (0.1575 inches) for consistent parting and groove dimensions
• MTCVD-applied TiCN/Al2O3/TiN coating for extended tool life and heat resistance
• Grade 4225 solid carbide substrate balances toughness and wear resistance
• Neutral lead angle and neutral hand for straight radial plunge cuts
• 5E chipbreaker geometry promotes reliable chip evacuation
• 0.20 mm corner radius minimizes stress concentration at groove corners

Compatibility

Designed for use with Sandvik Coromant T-Max Q-Cut parting and grooving toolholders accepting insert size code 40 and insert style N151.2 with a clamp-style holding method.

Installation Notes

This insert is installed and replaced by CNC machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamping hardware specified for the T-Max Q-Cut toolholder to secure the insert — do not overtighten or substitute non-OEM clamp screws. Inspect the insert seat for chips or debris before seating the new insert to ensure proper contact and repeatability.
