Sandvik Coromant 5765637 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 5765637 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drill bodies. Manufactured to grade 1044 with a TiAlN coating applied via PVD process, this insert delivers hard, wear-resistant cutting performance in a range of ferrous and non-ferrous materials. The square insert geometry features an 880 insert style with LM chipbreaker, an inscribed circle of 0.7047 inches (17.90 mm), a corner radius of 0.0315 inches (0.80 mm), and a thickness of 0.2165 inches. Installation and replacement are performed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for indexable drilling operations in CNC machining centers, turning centers with live tooling, and dedicated drill presses where controlled chip formation and consistent hole quality are required. The LM chipbreaker geometry promotes efficient chip evacuation in medium-duty drilling applications. It is sold individually with a minimum order quantity of 10 units, making it appropriate for shops that maintain a standing insert inventory for high-volume drilling programs.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per applicable safety procedures. Use the correct Torx or hex key specified by the drill body manufacturer to seat the insert clamp screw to the appropriate engagement - do not overtighten or use impact tools on the clamp screw. Inspect the pocket seating surface for debris or damage before indexing or replacing inserts. Confirm insert grade and chipbreaker selection against the material and feed rate requirements of the application before resuming operation.
