Sandvik Coromant 5765679 Indexable Drill Insert 880GR 1044

Product Description

The SANDVIK COROMANT 5765679 is a solid carbide indexable drill insert designed for use in 880-series indexable drills. Manufactured to grade 1044 with a TiAlN coating applied via PVD process, this insert delivers wear resistance and thermal stability in demanding drilling operations. It features a square shape with a GR chipbreaker geometry and a 0.40 mm corner radius. The inscribed circle measures 4.90 mm (0.1929 inches) and the insert thickness is 0.0945 inches. Machining professionals and tool-crib technicians working in metalworking, job-shop, and production environments install and index these inserts during routine tooling maintenance.

This insert is suited for use in indexable drill bodies that accept the 880-series insert seat style, commonly found in CNC machining centers, turning centers configured for driven tooling, and dedicated drill presses handling ferrous and non-ferrous workpieces. The GR chipbreaker geometry is optimized for general-purpose drilling applications where controlled chip formation is required. The TiAlN PVD coating supports performance in dry or near-dry cutting conditions at elevated cutting speeds. This insert is sold individually, with a minimum order quantity of 10 units per order.

Key Features

• Solid carbide substrate provides rigidity and edge stability in interrupted and continuous cuts
• TiAlN PVD coating improves oxidation resistance and extends tool life at high cutting speeds
• GR chipbreaker geometry supports controlled chip evacuation in general drilling operations
• Square insert shape with 0.40 mm corner radius reduces stress concentration at the cutting edge
• Insert size 02C with 2.20 mm hole diameter for secure mechanical clamping in the drill body
• Inscribed circle of 4.90 mm (0.1929 inches) consistent with 880-series peripheral insert seat requirements

Compatibility

Designed as a replacement peripheral or center insert for SANDVIK COROMANT 880-series indexable drill bodies that accept the 02C square insert seat size with a 4.90 mm inscribed circle. Verify seat style and insert position (center vs. peripheral) against the specific drill body specification before ordering.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine in a locked-out, tagged-out state per applicable shop safety procedures. Use the correct Torx or hex key as specified by the drill body manufacturer to reach the proper clamping torque without over-tightening the insert screw. Inspect the insert seat and clamping screw for wear or debris before seating the new insert. Do not use damaged or deformed insert screws, as improper clamping can result in insert movement during cutting.
