Sandvik Coromant 5736965 Grooving Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5736965 is a solid carbide grooving insert designed for the T-Max Q-Cut system, used in external grooving and parting-off operations on CNC lathes and turning centers. It carries manufacturer grade 1125 with a PVD-applied TiAlN coating, delivering wear resistance and thermal stability in a range of workpiece materials. The insert features a neutral hand orientation, a 0.1575 inch (4.00 mm) cutting width, and a chip breaker style designated 4G. The ISO code for this insert is N151.3-400-40-4G 1125. Licensed machinists and CNC operators install this insert as part of a qualified T-Max Q-Cut toolholder system.

This insert is suited for grooving, parting, and shallow profiling in both production and job-shop turning environments. The 4G chip breaker geometry promotes controlled chip formation across a range of feed rates and materials. With a neutral rake angle of 11 degrees and a corner radius of 0.0079 inch (0.20 mm), it is applicable to general-purpose grooving where consistent groove width and wall finish are required. The multi-use designation indicates the insert can be indexed for more than one cutting edge per piece, making it cost-effective in high-run applications.

Key Features

• Solid carbide substrate with PVD TiAlN coating for elevated wear and heat resistance
• Cutting width of 0.1575 inches (4.00 mm) for precise groove dimensioning
• Neutral hand orientation compatible with straight-entry grooving toolholders
• 4G chip breaker geometry for controlled chip evacuation
• Corner radius of 0.0079 inches (0.20 mm) for sharp groove shoulders
• Multi-use insert design allows indexing for extended tool life per unit

Compatibility

Designed for use in SANDVIK COROMANT T-Max Q-Cut toolholder systems accepting insert style N151.3 with insert seat size 40. ISO code N151.3-400-40-4G 1125 identifies the correct holder and pocket pairing.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate Torx or hex key torque tool as specified by the toolholder manufacturer for the insert clamping screw — do not over-tighten or substitute fasteners. Verify insert seating and clamping integrity before resuming cutting operations.
