Sandvik Coromant 5765612 Indexable Drill Insert 880LM H13A

Product Description

The SANDVIK COROMANT 5765612 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drills. Manufactured in the H13A uncoated carbide grade with the LM chipbreaker geometry, this insert is built for controlled chip formation during drilling operations in a range of workpiece materials. The square insert shape measures 0.2244 inches on the inscribed circle with a 0.1024-inch thickness and a 0.5 mm (0.0197-inch) corner radius. Uncoated solid carbide construction delivers consistent edge geometry and is well suited to applications where coated grades are not required or where re-grinding potential is a factor. Licensed machinists, CNC operators, and toolroom technicians typically specify this insert for precision drilling applications.

This insert is configured for use in 880-series indexable drill bodies requiring an 03C size square insert with the LM chipbreaker. Typical applications include through-hole and blind-hole drilling on CNC machining centers and turning centers in job shop, production, and aerospace environments. The uncoated H13A grade is commonly applied when machining materials where thermal coating interaction is a concern or where sharp, uncoated edges are preferred for edge integrity. The 2.5 mm mounting hole diameter supports secure seating and positive location within the insert pocket.

Key Features

• Solid carbide construction in uncoated H13A grade for consistent edge sharpness
• LM chipbreaker geometry designed for controlled chip evacuation during drilling
• Square insert shape, 03C size, with 0.2244-inch inscribed circle
• 0.5 mm corner radius (0.0197 inches) for edge strength and hole finish quality
• 2.5 mm (0.0984-inch) mounting hole for positive pocket location
• Bright/uncoated finish — no coating delamination risk at elevated feeds

Compatibility

Designed as a replacement insert for 880-series indexable drill bodies requiring an 03C square insert with LM chipbreaker geometry. Confirm pocket style, insert size designation, and screw torque specification in the toolholder documentation before installing.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician with the spindle locked and machine in a de-energized, zero-energy state per applicable lockout/tagout procedures. Use the correct Torx or hex key driver at the manufacturer-specified torque for the clamping screw — do not overtighten, as this can crack the carbide insert or damage the pocket. Inspect the insert pocket seating surface for chips or debris before installation. Consult the toolholder documentation for correct insert orientation relative to the cutting edge index position.
