Sandvik Coromant 5756265 Indexable Drill Insert WCMX58

Product Description

The SANDVIK COROMANT 5756265 is a WCMX-style indexable drill insert designed for use in indexable insert drills performing hole-making operations in metal. Built from solid carbide with a multi-layer MTCVD-applied TiCN and Al2O3 coating, this insert offers the wear resistance and thermal stability required for demanding drilling cycles. It features a 0.5 inch (12.70 mm) inscribed circle, a 3/16 inch (0.1875 inch) thickness, and a 1.20 mm corner radius. The trigon shape with a 7-degree relief angle and chipbreaker designation 58 positions it for efficient chip control in right-hand cutting applications. Installation is performed by CNC machinists and tooling technicians in production or job-shop environments.

This insert is suited for indexable drill bodies that accept WCMX insert geometry in size 8. Typical applications include through-hole and blind-hole drilling in steel, cast iron, and similar ferrous materials at production feeds and speeds where coating durability is critical. The right-hand cutting direction makes it appropriate for standard spindle rotation setups. The 3040 manufacturer grade identifies the specific carbide substrate and coating combination optimized for this class of drilling work. Machine operators and tooling specialists working with indexable drill systems will recognize this insert in common production drilling programs.

Key Features

• Solid carbide substrate with MTCVD-applied TiCN and Al2O3 multi-layer coating for extended tool life
• WCMX insert style, size 8, with trigon shape and 7-degree relief angle
• 0.5 inch inscribed circle and 0.1875 inch thickness for precise seating in compatible drill bodies
• 1.20 mm corner radius with chipbreaker designation 58 for controlled chip formation
• Right-hand cutting direction for standard CNC and manual spindle setups
• Manufacturer grade 3040 identifies substrate and coating combination for ferrous drilling applications

Compatibility

Designed as an OEM-style replacement insert for indexable drill bodies that accept WCMX-style inserts in size 8 with a 0.5 inch inscribed circle. Confirm pocket geometry, clamping method, and insert size against your drill body specification before ordering.

Installation Notes

Insert seating and clamping should be performed with the machine powered down and the spindle locked. Use the torque tool specified by the drill body manufacturer when securing the clamping screw to avoid seat damage or insert cracking. Inspect the pocket and clamping surfaces for chips or debris before seating a new insert. Replacement of indexable inserts is typically performed by the machine operator or tooling technician without special trade licensing, but shop safety protocols and machine-specific lockout procedures must be followed.
