Sandvik Coromant 5756232 WCMX53 3040 Indexable Drill Insert

Product Description

The SANDVIK COROMANT 5756232 is a solid carbide indexable drill insert in WCMX53 geometry, manufactured to grade 3040 and coated with TiCN and Al2O3 via an MTCVD process. The trigon-shaped insert features a 0.5 inch (12.70 mm) inscribed circle, a 0.1875 inch (3/16 inch) thickness, and a 1.20 mm corner radius, making it suited for high-performance indexable drilling operations. The 7-degree relief angle and 53 chipbreaker designation work together to control chip evacuation in demanding cutting applications. Installed by machinists and tool-room professionals, this insert is a direct drop-in replacement component for compatible Sandvik Coromant indexable drill bodies.

This insert is designed for use in indexable drilling applications across CNC machining centers, turning centers with live tooling, and dedicated drill presses operating in production environments. The right-hand cutting direction suits standard spindle-rotation setups. The MTCVD TiCN and Al2O3 coating combination is selected for wear resistance and thermal stability when drilling steel and other ferrous materials at moderate-to-high cutting speeds. The 0.1693 inch (4.30 mm) hole diameter accommodates the standard clamping screw used in WCMX-style insert seats.

Key Features

• Solid carbide substrate with MTCVD TiCN and Al2O3 multilayer coating for wear and heat resistance
• WCMX53 insert style with trigon shape and 7-degree relief angle for positive cutting geometry
• 0.5 inch inscribed circle and 0.1875 inch thickness to fit standard WCMX insert pockets
• 1.20 mm corner radius (0.0472 inch) for edge strength in drilling applications
• Right-hand cutting direction for conventional CNC spindle setups
• Grade 3040 carbide substrate optimized for steel and ferrous drilling

Compatibility

Designed as an OEM-style replacement insert for indexable drill bodies accepting WCMX insert style with an 8 insert size designation and a standard 4.30 mm clamping screw hole. Confirm pocket geometry and screw size against your drill body documentation before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating any indexable insert. Use the correct Torx or hex key torque driver specified by the drill body manufacturer for the clamping screw — do not over-tighten or substitute fasteners. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert.
