Sandvik Coromant 5765740 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 5765740 is a solid carbide indexable drill insert designed for use in compatible 880-series indexable drill bodies. Carrying the 1044 manufacturer grade with a PVD-applied TiAlN coating, this insert is engineered for demanding drilling operations where heat resistance and edge retention are critical. The square insert shape features an LM chipbreaker geometry and a 0.60 mm corner radius. With an inscribed circle diameter of 12.35 mm (0.4862 inches) and a thickness of 0.1575 inches, this insert is sized for precise fitment in its designated pocket. Machining professionals and toolroom technicians will recognize this as a direct-replacement peripheral or center insert for the 880 drill platform.

This insert is suited for use in CNC turning centers, machining centers, and dedicated drilling machines running 880-series indexable drill bodies. It is intended for applications involving steel, stainless steel, and other materials where TiAlN coating provides thermal and chemical wear resistance. The LM chipbreaker geometry supports chip evacuation in through-hole and blind-hole drilling scenarios. Insert size designation is 07C, and the hole diameter for the mounting screw is 4.00 mm (0.1575 inches). Sold individually, with a minimum order quantity of 10 units.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before accessing the drill body pocket. Use the correct Torx or hex key as specified by the drill body manufacturer to seat and torque the clamping screw - do not substitute tools or exceed the fastener specification. Inspect the pocket seating surfaces for damage or debris before indexing or replacing inserts.
