Sandvik Coromant 5724919 Turning Insert CNMG433-WM 3210

Product Description

The SANDVIK COROMANT 5724919 is a CNMG-style indexable turning insert from the T-Max P series, designed for external turning operations on CNC lathes and turning centers. Built from solid carbide and CVD-coated with a TiCN, Al2O3, and TiN multilayer stack in manufacturer grade 3210, this insert delivers wear resistance and thermal protection in demanding cut conditions. It features an 80-degree diamond shape, a neutral hand orientation, a 3/64-inch corner radius, and a Wiper Edge geometry for improved surface finish. The WM chip breaker designation targets stable, controlled chip formation. Licensed machinists and CNC programmers are the primary installers and operators of this insert.

This insert is engineered for turning cast iron workpiece materials, classified under ISO material code K. The T-Max P series is a widely used platform in production turning environments, covering both roughing and finishing passes depending on depth of cut and feed rate selection. The CNMG433-WM 3210 suits operations where surface finish quality and insert life on gray and nodular cast iron are priorities. It is appropriate for use in both light and moderate interrupted cuts where the CVD multilayer coating and WM chip breaker geometry provide adequate edge security and chip control.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and heat management
• 80-degree diamond insert shape (Shape Code C) with neutral hand orientation
• WM chip breaker geometry for controlled chip formation on cast iron
• Wiper Edge design for improved surface finish at standard feed rates
• Clamp and pin insert holding method for secure, repeatable seating
• 4 usable cutting edges per insert for cost-effective tooling utilization

Compatibility

Designed as an OEM-specification replacement insert for SANDVIK COROMANT T-Max P series turning toolholders that accept CNMG 12 04 12 geometry inserts (ISO code CNMG 12 04 12-WM 3210). Confirm toolholder pocket geometry, clamp style, and shim specification before installation.

Installation Notes

This insert is installed and indexed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before changing or indexing inserts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer to seat the insert properly — do not overtighten by hand or with unspecified tools. Inspect the insert pocket, shim, and clamp for wear or damage each time the insert is indexed.
