Sandvik Coromant 6633730 Indexable Drill Insert Square

Product Description

The SANDVIK COROMANT 6633730 is a solid carbide indexable drill insert engineered for use in indexable drill bodies requiring square-style inserts with a GM chipbreaker. Carrying manufacturer grade 4334, this insert features a CVD-applied TiCN/Al2O3/TiN multilayer coating that provides wear resistance and thermal stability during high-feed drilling operations. The inscribed circle measures 18.6 mm (0.7323 inches), with an insert thickness of 0.2165 inches and a corner radius of 0.80 mm (0.0315 inches). It is sized at 090608 and designed for right-hand cutting. Machinists and tool-crib technicians working in metalcutting environments will specify this insert for consistent hole quality and extended tool life.

This insert is suited for use in 880-series indexable drill toolholders requiring square-style GM chipbreaker inserts. Typical applications include drilling operations in steel, stainless steel, and cast iron in CNC machining centers and turning centers. The multilayer CVD coating supports dry or wet cutting depending on workpiece material and machine capability. The 880GM designation identifies both the insert style and chipbreaker geometry, making this insert application-specific to that toolholder family.

Key Features

• Solid carbide substrate with CVD-applied TiCN/Al2O3/TiN multilayer coating for wear and heat resistance
• GM chipbreaker geometry designed for chip control in drilling operations
• Square insert shape, insert style 880, sized 090608
• Right-hand cutting direction
• Corner radius of 0.80 mm (0.0315 inches) for edge stability
• Inscribed circle of 18.6 mm (0.7323 inches) for precise seating in compatible drill bodies

Compatibility

Designed for use in 880-series indexable drill toolholders that accept square-style inserts with a GM chipbreaker and 090608 insert size. Verify toolholder seat specifications before installation to confirm correct insert geometry and hole diameter fitment.

Installation Notes

Insert replacement is performed by machining technicians using the appropriate Torx or hex key for the clamping screw — refer to the toolholder manufacturer's documentation for fastener specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket seat for wear or debris before seating the new insert. Do not overtighten the clamping screw; follow the toolholder OEM torque guidance found in that product's documentation.
