Sandvik Coromant 6770724 Indexable Drill Insert 880GR

Product Description

The SANDVIK COROMANT 6770724 is a solid carbide indexable drill insert designed for use with 880-series modular indexable drills. This insert carries the 4344 manufacturer grade and features a TiAlN2 coating applied via PVD process, providing thermal resistance and extended tool life in demanding drilling operations. The parallelogram insert shape fits the 880 insert style pocket and is configured for right-hand cutting. Key dimensions include a 4.80 mm (0.1890 inch) inscribed circle, a 0.40 mm (0.0157 inch) corner radius, and a thickness of 0.0866 inches. It is installed by machinists and tooling technicians on CNC machining centers and drill presses in metalworking applications.

This insert is suited for production drilling in ferrous and non-ferrous metals where a controlled corner radius and positive chipbreaker geometry support chip evacuation and hole quality. The GR chipbreaker designation is intended for general-purpose drilling conditions. The insert size designation is 010204, and it ships as a single-piece unit. Typical applications include through-hole and blind-hole drilling in medium to high-volume manufacturing environments on horizontal and vertical machining centers.

Key Features

• Solid carbide substrate with TiAlN2 PVD coating for heat and wear resistance
• 880 insert style with parallelogram shape for secure pocket seating
• 4344 manufacturer grade optimized for general-purpose metalcutting
• GR chipbreaker geometry promotes controlled chip formation and evacuation
• Right-hand cutting configuration
• 0.40 mm corner radius reduces edge stress and improves hole finish

Compatibility

Designed as a direct-fit replacement insert for SANDVIK COROMANT 880-series indexable drill bodies that accept the 880 insert style in the 010204 insert size with a parallelogram seating pocket.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power locked out. Use a calibrated torque wrench and the correct Torx or insert-clamping key specified for the 880 drill body to seat the insert properly. Inspect the insert pocket for chips or debris before seating a new insert. Never force an insert into a damaged or worn pocket.
