Sandvik Coromant 5908964 Turning Insert H13A Carbide

Product Description

The SANDVIK COROMANT 5908964 is a solid carbide, uncoated turning insert in the CNGG432-SGF geometry, designed for precision metal-turning operations on CNC and manual lathes. It carries an 80-degree diamond shape (insert shape code C) with a neutral hand orientation, making it suitable for both roughing and finishing passes depending on feed and depth parameters. The H13A uncoated carbide grade performs best in applications where coating would risk edge buildup or thermal cracking. With a 0.5-inch inscribed circle, a 3/16-inch thickness, and a 1/32-inch corner radius, this insert fits standard CNGG toolholders commonly found in production turning environments. Licensed machinists and CNC operators are the primary users.

This insert is engineered for turning stainless steel as its primary workpiece material, with secondary suitability for superalloys and titanium. The SGF chipbreaker geometry is optimized for these difficult-to-machine materials, providing controlled chip formation and reduced cutting forces at moderate feed rates. It is part of the SANDVIK COROMANT T-Max P series, which is a well-established platform for external and internal turning across a wide range of production environments. The ISO designation for this insert is CNGG120408-SGF H13A. Typical applications include shaft turning, facing, and contour work on stainless and high-temperature alloy components in aerospace, medical, and industrial manufacturing settings.

• 1/32-inch corner radius (0.0313 inches) supports fine surface finish requirements
• Four cutting edges per insert for extended tool life per unit
• Part of the T-Max P series platform, compatible with clamp and pin insert holding methods

Compatibility

Designed for use in CNGG-style toolholders accepting a 432 insert size with clamp or pin holding method. ISO code CNGG120408-SGF H13A. Primary workpiece material: stainless steel (ISO material code M). Secondary workpiece materials: superalloy and titanium (ISO material code S). Part of the SANDVIK COROMANT T-Max P series.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Before changing inserts, ensure the machine spindle is fully stopped and all stored energy in the toolholder is released. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert clamp or pin. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper support and edge engagement.
