Sandvik Coromant 6770725 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 6770725 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drill bodies. Manufactured to grade 4344 with a PVD-applied TiAlN2 coating, this insert delivers wear resistance and thermal stability in demanding drilling operations. The parallelogram insert shape features an 880LM chipbreaker geometry with a 4.80 mm (0.1890 inches) inscribed circle and a 0.40 mm (0.0157 inches) corner radius. Thickness measures 0.0866 inches. This insert is intended for installation by machinists and tooling technicians working in metal-cutting environments where precision bore entry and chip control are critical.

This insert is suited for indexable drill applications in ferrous and non-ferrous metal-cutting operations across production machining environments. The LM chipbreaker geometry is optimized for light-to-medium chip loads in drilling. The right-hand insert hand designation indicates directional orientation for proper seating in the drill body pocket. With an insert size designation of 010204 and a hole diameter of 2.2 mm, this insert fits 880-series drill bodies that accept this pocket geometry and size class.

Key Features

• Solid carbide construction with PVD TiAlN2 coating for extended tool life in metal drilling
• 880LM chipbreaker geometry for controlled chip formation in light-to-medium cutting conditions
• Parallelogram insert shape with right-hand orientation for proper 880-series pocket seating
• 4.80 mm inscribed circle with 0.40 mm corner radius for precise cutting edge geometry
• Grade 4344 carbide substrate suited for a broad range of workpiece materials

Compatibility

Designed for use with 880-series indexable drill bodies that accept a parallelogram insert pocket with an 010204 insert size and a 2.2 mm mounting hole diameter. Verify pocket geometry and insert size designation against the drill body specification before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the insert clamping screw and follow the drill body manufacturer's specified seating procedure. Inspect the pocket seating surface for chips or debris before installing a fresh insert to ensure full contact and accurate cutting geometry.
