Sandvik Coromant 6633732 Indexable Drill Insert 880LM 4334

Product Description

The SANDVIK COROMANT 6633732 is a solid carbide indexable drill insert designed for use in 880-series indexable drills. It carries the 880LM insert style designation with a Grade 4334 substrate and a CVD-applied TiCN/Al2O3/TiN multilayer coating. The square insert geometry features an 18.6 mm (0.7323 inch) inscribed circle, a 1.00 mm (0.0394 inch) corner radius, and a thickness of 0.2165 inches. The LM chipbreaker geometry promotes controlled chip evacuation during deep-hole drilling operations. This insert is installed by machinists and CNC operators in metalworking and production drilling environments.

The 6633732 is suited for right-hand cutting applications in indexable drilling operations on machining centers and CNC lathes. The 880 insert style is commonly applied in production environments where hole quality, chip control, and insert life in steel and cast iron are priorities. The CVD multilayer coating provides wear resistance and thermal stability across a range of cutting parameters. This insert ships individually and is available in multiples of 10 units as required by the manufacturer minimum order quantity.

Compatibility

Designed as a direct replacement insert for SANDVIK COROMANT 880-series indexable drills accepting the 880 insert style in size 090610 with a square geometry and 18.6 mm inscribed circle.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the spindle locked and all power removed from the machine tool. Use the correct torx or hex key specified for the 880-series drill body insert pocket to achieve proper clamping torque without cracking the carbide. Inspect the insert pocket and clamping screw for debris or damage before seating the new insert. Never force an insert into a pocket with a damaged seating surface, as this will compromise edge position and can fracture the substrate.
