Sandvik Coromant 5765751 Indexable Drill Insert 880GR

Product Description

The SANDVIK COROMANT 5765751 is a solid carbide indexable drill insert designed for use in indexable insert drills requiring precise, repeatable hole-making performance. Manufactured to insert style 880 with a GR chipbreaker, this insert carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in ferrous and hardened materials. The square insert geometry features an 8.40 mm inscribed circle (0.3307 inches), a corner radius of 0.50 mm (0.0197 inches), and a thickness of 0.1181 inches. Installation and replacement are handled by machinists and tooling technicians in production and job-shop environments.

This insert is suited for indexable drill bodies calling for an 880-series square insert in size 05C. Typical applications include through-hole and blind-hole drilling in steel, stainless steel, and cast iron on CNC machining centers and lathes with live tooling. The GR chipbreaker geometry promotes chip evacuation in medium-to-hard workpiece materials. The 3.20 mm hole diameter (0.1260 inches) accommodates the standard mounting screw for 880-series drill bodies.

Key Features

• Solid carbide substrate for rigidity and wear resistance in demanding drilling applications
• TiAlN coating via PVD process for elevated heat resistance and extended cutting edge life
• GR chipbreaker geometry engineered to promote controlled chip formation and evacuation
• Square insert shape (880 style, size 05C) for direct compatibility with corresponding drill bodies
• 0.50 mm corner radius reduces insert chipping at entry and exit of the cut
• Manufacturer grade 1044 for consistent performance across production runs

Compatibility

Designed as a replacement insert for SANDVIK COROMANT 880-series indexable drill bodies requiring a square, size 05C insert with an 880GR chipbreaker geometry and 1044 grade solid carbide. Confirm drill body insert pocket specifications before ordering.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine in a locked-out state per applicable safety procedures. Use the correct torque wrench and manufacturer-specified screw for the 880-series drill body to seat the insert properly in the pocket. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert. Handle solid carbide inserts with care to avoid chipping the cutting edges prior to use.
