Sandvik Coromant 5765734 Indexable Drill Insert 880GM

Product Description

The SANDVIK COROMANT 5765734 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drill bodies. This insert carries the 1044 manufacturer grade with a TiAlN coating applied via PVD process, providing wear resistance and thermal stability in demanding drilling operations. It features a square shape with a GM chipbreaker geometry, a 0.4862-inch (12.35 mm) inscribed circle, and a 0.6 mm corner radius. Machining professionals and toolroom technicians working in ferrous and non-ferrous materials rely on this insert type for consistent hole quality and extended tool life in production drilling environments.

This insert is suited for use in CNC machining centers and drill presses where indexable drill tooling is standard. The 880GM designation indicates compatibility with 880-series drill bodies requiring a square insert with a 07C insert size designation. Applications span general-purpose drilling in job shops, aerospace component manufacturing, and high-volume production lines. The PVD TiAlN coating makes it a strong candidate for dry or minimal-lubrication cutting strategies where heat generation at the cutting edge is a primary concern.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for thermal and wear resistance
• GM chipbreaker geometry for controlled chip evacuation in drilling applications
• Square insert shape with 0.4862-inch (12.35 mm) inscribed circle
• 0.6 mm corner radius for edge stability during entry and exit
• Insert size 07C with 0.1575-inch (4.0 mm) hole diameter for secure seating in the drill body
• 1044 manufacturer grade suited to a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement insert for 880-series indexable drill bodies requiring a square, 07C-size solid carbide insert with a GM chipbreaker and 12.35 mm inscribed circle.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the drill body manufacturer to achieve correct clamping torque — do not overtighten or undertighten the insert screw. Inspect the insert pocket and clamping screw for debris or wear before seating the new insert.
