Sandvik Coromant 5765680 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 5765680 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drill bodies. This insert carries the 1044 manufacturer grade and features a TiAlN coating applied via PVD process, delivering enhanced wear resistance and thermal stability at cutting speeds common in metal removal operations. The square insert shape with an LM chipbreaker geometry promotes reliable chip evacuation during deep-hole and through-hole drilling operations. With an inscribed circle of 4.90 mm (0.1929 inches) and a corner radius of 0.40 mm (0.0157 inches), this insert is suited for precision drilling in steel and similar workpiece materials. Licensed machinists and CNC toolroom technicians are the primary installers.

This insert is used in indexable drill tooling systems where replaceable carbide inserts are seated in a drill body to perform metal drilling operations. The 880LM designation identifies both the insert series (880) and the chipbreaker style (LM), which is optimized for low-to-medium feed rates in general-purpose drilling. Typical applications include production machining environments using CNC lathes, machining centers, and turret drills working with ferrous and non-ferrous materials. The insert size designation is 02C with a hole diameter of 2.20 mm (0.0866 inches) for clamping screw fitment.

Key Features

• Solid carbide substrate with TiAlN PVD coating for elevated hardness and oxidation resistance
• LM chipbreaker geometry designed for controlled chip formation at low-to-medium feeds
• Square insert shape (Style 880) for secure seating in compatible drill body pockets
• Inscribed circle of 4.90 mm (0.1929 inches) for precise indexable positioning
• Corner radius of 0.40 mm (0.0157 inches) to balance edge strength and surface finish
• Clamping hole diameter of 2.20 mm (0.0866 inches) for positive mechanical retention

Compatibility

Designed as an OEM-style replacement insert for SANDVIK COROMANT 880-series indexable drill bodies that accept 02C insert size seats with compatible clamping screw specifications.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Before indexing or replacing inserts, the machine must be powered down and the spindle fully stopped. Use the correct Torx or hex key specified for the clamping screw of the drill body to seat the insert firmly without over-torquing the screw. Inspect the insert pocket seating surfaces for chips or debris before installing a new insert, as contamination can cause improper seating and premature insert failure.
