Sandvik Coromant 6633706 Indexable Drill Insert 880GM

Product Description

The SANDVIK COROMANT 6633706 is a solid carbide indexable drill insert in the 880GM chipbreaker style, designed for use in Sandvik Coromant 880 series indexable insert drills. This insert features a CVD-applied TiCN/Al2O3/TiN multilayer coating that provides wear resistance and thermal protection during high-speed drilling operations. The square insert shape with right-hand cutting direction suits through-hole and blind-hole drilling in steel and cast materials. With a 6.00 mm (0.2362 inch) inscribed circle and a 0.50 mm (0.0197 inch) corner radius, this insert is suited for precision metal-cutting applications. Licensed HVAC, machining, and metalworking professionals select this insert for production drilling environments where consistent tool life and chip control are required.

This insert is used in industrial drilling applications on CNC machining centers, drill presses, and horizontal boring machines. The 880GM chipbreaker geometry is engineered for controlled chip formation in steel and similar ferrous workpiece materials. The insert size designation is 030305, and the mounting hole diameter is 2.50 mm (0.0984 inch), which corresponds to standard 880-series toolholder seating requirements. It is a single-piece insert sold as a replacement for worn or damaged positions in multi-insert drill bodies.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable lockout/tagout procedures. Use the correct Torx or hex key driver specified for the toolholder to seat the insert clamp screw without over-torquing. Inspect the insert pocket and seating surface for debris or damage before installing a new insert. Follow the toolholder manufacturer's recommended cutting parameters for feed rate and speed when returning the tool to service.
