Sandvik Coromant 5765686 Indexable Drill Insert 880LM H13A

Product Description

The SANDVIK COROMANT 5765686 is a solid carbide indexable drill insert designed for use in 880-series indexable drills. Designated grade H13A with an LM chipbreaker, this insert is supplied in an uncoated bright finish, making it well-suited for applications where coating interaction with the workpiece material is a concern. The square insert geometry features an 18.60 mm inscribed circle, a 1.00 mm corner radius, and a thickness of 0.2165 inches (5.50 mm). Installation and replacement are performed by machinists and tooling technicians in CNC turning centers, machining centers, and drill press setups.

This insert is used in metal-cutting drilling operations across light manufacturing, aerospace, automotive, and general machining environments. The 880 insert style and LM chipbreaker combination is appropriate for producing through-holes and blind holes in a range of ferrous and non-ferrous materials where controlled chip evacuation is required. The insert fits 880-series drill bodies requiring a 09P size seat with a 4.70 mm hole diameter for the clamping screw.

Compatibility

Designed as an OEM-style replacement insert for SANDVIK COROMANT 880-series indexable drill bodies requiring an 09P square seat and 4.70 mm screw hole diameter. Specific drill body compatibility should be verified against the SANDVIK COROMANT 880-series tooling catalog using the insert size and grade designations provided.

Installation Notes

Insert replacement is performed by qualified machinists or tooling technicians. Disengage and lock out the machine spindle before seating or removing any indexable insert. Use the correct torx or hex key to the tool manufacturer's specified seating procedure to ensure the insert is fully seated against the pocket walls before resuming operation. Inspect the pocket seat for debris or damage before installing a new insert, as a contaminated or worn pocket will affect runout and tool life.
