Sandvik Coromant 5756918 Turning Insert Wpmt Carbide

Product Description

The SANDVIK COROMANT 5756918 is a solid carbide turning insert in the WPMT style, engineered for precision metal cutting on CNC lathes and turning centers. It carries a multilayer TiCN, Al2O3, and TiN coating — grade 2025 — that provides wear resistance and thermal protection during continuous and light interrupted cuts. The insert features an 80-degree trigon shape with a 1/32-inch corner radius, a 1/4-inch inscribed circle, and a 3/32-inch insert thickness. A screw-type holding method secures it in compatible toolholders. This insert is installed by machinists and CNC operators in production and job-shop environments.

This insert is suited for general turning applications where tight tolerances and consistent surface finish are required. The WPMT insert style with chip breaker code T is designed to manage chip flow during medium-duty turning. It is appropriate for use on steel and similar workpiece materials in both production and maintenance machining environments. The ISO code for this insert is WPMT 04 02 08-MM 2025, which can be used to cross-reference compatible toolholder systems. Each package contains one insert, with a minimum order quantity of 10 units.

Key Features

• Grade 2025 multilayer coating: TiCN, Al2O3, and TiN for extended tool life
• 80-degree trigon insert shape (Shape Code W) for versatile turning geometry
• 1/4-inch inscribed circle with a 1/32-inch corner radius for controlled cutting edge engagement
• Screw-type insert holding method for secure clamping and repeatable indexing
• T-style chip breaker for effective chip management during medium-duty cuts
• Clearance Code P and Tolerance Code M for standard WPMT toolholder compatibility

Compatibility

Designed for use in WPMT-style screw-clamping toolholders. The ISO designation WPMT 04 02 08-MM 2025 should be used to confirm fitment with specific toolholder systems. No additional compatible model or system data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a safe, locked-out state. Use the correct torx or hex key to torque the clamping screw to the toolholder manufacturer's specification — do not overtighten, as this can fracture the insert. Inspect the toolholder pocket for debris or wear before seating the insert. Follow shop safety procedures and applicable OSHA machining guidelines when indexing or replacing cutting inserts.
