Sandvik Coromant 6626851 Indexable Drill Insert 880LM 4324

Product Description

The SANDVIK COROMANT 6626851 is a solid carbide indexable drill insert designed for use in 880-style indexable drill bodies. This insert carries the 4324 manufacturer grade with a CVD-applied TiCN and Al2O3 coating, providing wear resistance and thermal stability during high-feed drilling operations. The square insert geometry features an LM chipbreaker and a 1 mm corner radius. With an inscribed circle of 18.60 mm (0.7323 inches) and a thickness of 0.2165 inches, it is suited for demanding hole-making applications in ferrous and difficult-to-machine materials. Licensed machinists and CNC operators are the primary end users.

This insert is intended for use in indexable drill tooling systems that accept the 880 insert style with a square shape and size designation 090610. It fits production environments including job shops, aerospace machining, and general metalworking where consistent hole quality and insert longevity are required. The LM chipbreaker geometry assists with chip control in through-hole and blind-hole drilling scenarios. Applications typically involve CNC machining centers and turning centers equipped with driven tool holders or live tooling where indexable drill bodies are mounted.

Key Features

• Solid carbide substrate with 4324 manufacturer grade for high hardness and edge stability
• CVD-applied TiCN and Al2O3 dual-layer coating for thermal and abrasion resistance
• LM chipbreaker geometry designed for effective chip control in drilling operations
• Square insert shape with 1 mm corner radius for stable cutting engagement
• 18.60 mm inscribed circle (0.7323 inches) fits 880-style indexable drill bodies with size 090610 designation
• Insert hole diameter of 4.7 mm for secure clamping in compatible drill bodies

Compatibility

Designed for use in 880-style indexable drill bodies that accept a square insert with size designation 090610 and a 4.7 mm clamping hole diameter. Confirm drill body manufacturer specifications before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool is secured or removed from the turret before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the drill body manufacturer to reach the recommended clamp screw seating without over-torquing. Inspect the insert pocket and clamping screw for debris or wear before seating the new insert.
