Sandvik Coromant 5765681 Indexable Drill Insert 880LM H13A

Product Description

The SANDVIK COROMANT 5765681 is a solid carbide indexable drill insert designed for use in compatible 880-series indexable drills. Carrying the H13A grade designation with an LM chipbreaker geometry, this insert is supplied in an uncoated bright finish, making it suitable for applications where coating-induced dimensional tolerances are a concern. The square insert shape features a 1.00 mm corner radius and a 15.45 mm inscribed circle (0.6083 inches), with a thickness of 0.1772 inches. It is intended for installation by machinists and tooling technicians in metal-cutting drilling operations on CNC machining centers and manual drill presses.

This insert is sized to the 08P insert size standard and is compatible with 880-series indexable drill bodies that accept square LM-geometry peripheral or center inserts. Typical applications include hole-making operations in ferrous and non-ferrous materials across job shop, production machining, and manufacturing environments. The uncoated H13A solid carbide grade is particularly relevant in applications where post-machining coating or tight dimensional control is required. The LM chipbreaker promotes effective chip control during drilling cycles.

Key Features

• Solid carbide construction in H13A grade for consistent cutting performance
• Uncoated bright finish for dimensional precision and compatibility with sensitive workpiece materials
• LM chipbreaker geometry for controlled chip evacuation during drilling
• Square insert shape with 1.00 mm corner radius
• 15.45 mm (0.6083 inch) inscribed circle with 4.70 mm mounting hole diameter
• Insert size 08P for direct fitment into corresponding 880-series drill bodies

Compatibility

Designed for use with SANDVIK COROMANT 880-series indexable drill bodies that accept 08P square inserts with LM chipbreaker geometry. Confirm insert seat type (peripheral or center) and drill body specification before installation.

Installation Notes

Installation of indexable drill inserts should be performed by qualified tooling technicians or machinists. Ensure the drill body and insert seat are clean and free of chips or debris before seating the insert. Use the correct torx or hex key to torque the clamping screw per the tool body manufacturer's documentation — do not over-torque. Always remove the tool from the machine spindle and follow lockout procedures before changing inserts.
