Sandvik Coromant 5737963 Milling Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5737963 is a solid carbide milling insert designed for high-performance metal cutting in demanding machining environments. It carries a manufacturer grade of 3040 with a CVD-applied TiCN and Al2O3 coating for wear resistance and thermal stability. The insert measures 11.5 mm wide and 4.95 mm thick, features a rectangular shape with a 0.80 mm corner radius, and delivers 4 cutting edges per insert. Rake is positive and relief angle is neutral, supporting stable chip formation across a range of milling operations. It is suited for machinists and CNC operators working in production environments where consistent tool life and surface finish on ferrous and hard workpiece materials are critical.

This insert is intended for use in milling applications involving steel, cast iron, and hard materials, corresponding to ISO material groups P, K, and H. It fits single-sided in the tool holder and is secured by screw clamping. The maximum depth of cut is 10.70 mm. The KM chip breaker geometry is optimized for controlled chip evacuation during face and shoulder milling operations. The insert is compatible with the L331.52 cutter series and is identified by ANSI and ISO code N331.1A-11 50 08E-KM3040, making it straightforward to cross-reference in tool management systems.

Key Features

• 4 cutting edges per insert for extended tool economy
• Positive rake geometry with KM chip breaker for controlled chip flow
• Corner radius of 0.80 mm reduces edge chipping on entry and exit
• Maximum depth of cut of 10.70 mm supports aggressive milling passes
• Compatible with L331.52 cutter series; screw-held single-sided mounting

Compatibility

Designed for use with the L331.52 cutter series. ANSI and ISO code N331.1A-11 50 08E-KM3040. Insert style N331.1A, size code 115008. Intended for primary workpiece materials steel, cast iron, and hard material (ISO P, K, H).

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the correct torx or hex key to the tool manufacturer's specified seating procedure when driving the clamping screw; do not overtighten by hand estimate alone. Inspect the pocket seat and clamping screw for wear or debris before seating a new insert.
