Sandvik Coromant 5765750 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 5765750 is a solid carbide indexable drill insert designed for use in 880-series indexable drills. It carries the 1044 manufacturer grade with a TiAlN coating applied via PVD process, delivering elevated heat and wear resistance in demanding drilling operations. The insert features a square shape with an LM chipbreaker geometry, an inscribed circle of 0.4016 inches (10.20 mm), a thickness of 0.1378 inches, and a corner radius of 0.0236 inches (0.60 mm). Machining professionals and toolroom technicians install these inserts as replaceable cutting edges in compatible indexable drill bodies used on CNC lathes, machining centers, and drill presses.

This insert is suited for metal-cutting applications where controlled chip formation and thermal stability are required. The LM chipbreaker geometry supports light-to-medium cutting conditions, making it applicable across a range of workpiece materials. The PVD-applied TiAlN coating reduces tool wear at elevated cutting temperatures. It is packaged individually and sold in multiples of 10, making it appropriate for shops that maintain consistent insert inventories for production drilling operations.

Installation Notes

Insert replacement should be performed by a qualified machining technician with the machine powered down, spindle locked, and all stored energy released before accessing the drill body. Use the appropriate Torx or hex key specified by the drill body manufacturer to seat the insert securely without overtightening the clamping screw. Inspect the insert pocket and clamping components for wear or damage before installing a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
