Sandvik Coromant 7080782 Turning Insert SNMG543-HM 4335

Product Description

The SANDVIK COROMANT 7080782 is a solid carbide turning insert in the SNMG style, designed for use in CNC and manual turning operations on metalcutting lathes. Manufactured under the T-Max P series, it carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across a range of workpiece materials. The insert features a 90-degree square shape with a neutral hand orientation, a 5/8 inch (0.6250 inch) inscribed circle, and a 3/64 inch (0.0469 inch) corner radius. Grade 4335 and the HM chip breaker geometry make this insert suited for medium to finishing turning passes. Machinists and tool-room technicians install this insert as part of a clamp-and-pin toolholding system.

This insert is used in turning centers and engine lathes for external and internal diameter operations where a square insert with a neutral hand is specified. The SNMG style with a 0-degree relief angle (clearance code N, tolerance code M) is common in production turning of steel and cast iron components. It is compatible with toolholders designed for the SNMG 15 06 12 ISO code. The T-Max P series from SANDVIK COROMANT targets general-purpose metal turning where consistent chip control and long edge life are required in medium-duty cutting conditions.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear and heat resistance
• SNMG insert style with 90-degree square shape and neutral hand orientation
• 5/8 inch (15.88 mm) inscribed circle for robust edge support
• 3/64 inch (1.19 mm) corner radius for medium to finish turning passes
• HM chip breaker geometry with grade 4335 for controlled chip formation
• Clamp and pin holding method compatible with standard SNMG toolholders

Compatibility

Designed for use in toolholders conforming to ISO code SNMG 15 06 12 with clamp-and-pin holding systems. Verify toolholder pocket geometry matches the SNMG insert style, 1/4 inch insert thickness, and 5/8 inch inscribed circle before installation.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Power down and lock out the machine spindle before seating or replacing inserts. Confirm the toolholder pocket and clamping pin are clean and free of chips before seating the insert. Follow the toolholder manufacturer's clamping torque specifications and do not use damaged or worn clamping hardware.
