Sandvik Coromant 5756137 Indexable Drill Insert WCMX58 235

Product Description

The SANDVIK COROMANT 5756137 is a solid carbide indexable drill insert designed for use in indexable insert drills in metalworking and machining operations. Classified under the WCMX insert style with a trigon (7-degree included angle) shape, this insert features a CVD-applied TiCN/TiN coating that provides wear resistance and thermal stability during high-speed drilling. The 3/8-inch inscribed circle and 5/32-inch thickness make it suitable for mid-range drill body applications. A 0.8 mm corner radius and right-hand cutting direction round out the key geometry. Installation is performed by machinists and tooling technicians working with compatible indexable drill bodies.

This insert is suited for drilling operations in ferrous and common engineering materials using indexable drill systems. The WCMX insert style is typically used in insert drills for through-hole and blind-hole applications in production machining environments, both manual and CNC. The 58 chipbreaker geometry promotes controlled chip formation and evacuation, which is critical for maintaining hole quality and extending drill body life in high-cycle machining.

Key Features

• Solid carbide substrate with CVD TiCN/TiN coating for wear and heat resistance

• 3/8-inch (9.53 mm) inscribed circle for compatible drill body fit
• 0.8 mm (0.0315 inch) corner radius for controlled cutting edge geometry
• 58 chipbreaker designation for effective chip control
• Right-hand cutting direction

Compatibility

Designed as an OEM-style replacement indexable drill insert for indexable insert drill bodies accepting the WCMX insert style with a size 6 insert and a 3.70 mm mounting hole diameter.

Installation Notes

Insert seating and torque should follow the drill body manufacturer's tool assembly specifications using the appropriate Torx or hex key. Power down and lock out all machine spindles before changing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Proper insert orientation and full pocket contact are critical to achieving on-center drilling and preventing premature insert or body failure.
