Sandvik Coromant 6626829 Indexable Drill Insert 880 Gm

Product Description

The SANDVIK COROMANT 6626829 is a solid carbide indexable drill insert engineered for use with 880-series indexable drills. This insert carries a CVD-applied TiCN and Al2O3 coating, which provides thermal resistance and wear protection during high-feed drilling operations in steel and cast materials. It features a square insert shape with a GM chipbreaker geometry, a 7.4 mm (0.2913 inch) inscribed circle, and a 0.1102-inch thickness. The 0.5 mm corner radius and right-hand cutting orientation make it suitable for precision hole-making in production environments. Licensed machinists and CNC operators working in metalworking, aerospace, and general manufacturing are the primary installers of this insert type.

This insert is designed for use in SANDVIK COROMANT 880-series indexable drill bodies in right-hand configurations. The GM chipbreaker geometry is well suited for general-purpose drilling in steel, stainless, and similar workpiece materials at moderate to high cutting speeds. It fits applications where consistent chip control and hole quality are required across medium to high production volumes. Insert size designation is 040305. This product is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by CNC machinists or tool-room technicians. Ensure the drill body is removed from the spindle and the machine is locked out before replacing inserts. Use the correct Torx or hex key specified for the 880-series clamping screw and follow the drill body manufacturer torque guidelines. Inspect the insert pocket seat and clamping screw for wear or debris before seating the new insert.
