Sandvik Coromant 6770753 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 6770753 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drills in metal-cutting operations. Manufactured to the 4344 grade with a TiAlN2 PVD coating, this insert delivers heat and wear resistance suited to demanding drilling applications in steel and cast materials. The square insert shape features a 15.45 mm inscribed circle, a thickness of 0.1772 inches, and a 1 mm corner radius, making it appropriate for precision hole-making in production environments. Installation and replacement are handled by machinists and tooling technicians working in CNC machining, job shop, or manufacturing settings.

This insert is used in high-feed indexable drilling applications where consistent hole quality and insert longevity are priorities. The LM chipbreaker geometry is suited for light to medium cutting conditions, helping manage chip evacuation in through-hole and blind-hole drilling. The right-hand cutting direction and square shape (Insert Size 080510) align with standard 880-series toolholder pocket specifications. Applications span general metalworking, including production drilling of steel, stainless, and similar workpiece materials in both horizontal and vertical machining centers.

Key Features

• Solid carbide construction with 4344 manufacturer grade for wear resistance in metal-cutting applications
• TiAlN2 coating applied via PVD process for improved heat resistance and tool life
• LM chipbreaker geometry for effective chip control in light to medium drilling conditions
• 1 mm corner radius reduces stress concentration at cutting edge corners
• Square insert shape (Insert Size 080510) for consistent seating in compatible 880-series pockets
• Right-hand cutting direction; 15.45 mm inscribed circle with 4.70 mm hole diameter

Compatibility

Designed as an OEM-style replacement insert for use in 880-series indexable drill toolholders that accept square-style inserts with a 15.45 mm inscribed circle and 080510 insert size designation.

Installation Notes

Insert replacement is performed by a machinist or tooling technician with the machine powered off and the spindle fully stopped. Use the appropriate Torx or hex key specified by the toolholder manufacturer to secure the insert clamp screw to the recommended seating torque per the toolholder documentation. Inspect the pocket seat for damage or debris before installing a new insert. Handle carbide inserts carefully to avoid chipping the cutting edges prior to use.
