Sandvik Coromant 6626845 Indexable Drill Insert 880GM 4324

Product Description

The SANDVIK COROMANT 6626845 is a solid carbide indexable drill insert designed for use with 880-series indexable drills in metal-cutting operations. Manufactured to the 4324 grade with a CVD-applied TiCN and Al2O3 coating, this insert delivers thermal and wear resistance suited to demanding drilling applications. The GM chipbreaker geometry controls chip evacuation in a wide range of workpiece materials. The insert features a 15.45 mm (0.6083 inch) inscribed circle, a square shape, and a 0.80 mm (0.0315 inch) corner radius. Installation is performed by licensed machinists and CNC machine operators in production and job-shop environments.

This insert is intended for use in SANDVIK COROMANT 880-series indexable drill bodies in right-hand cutting configurations. It is suited for drilling operations in materials including steel, stainless steel, and cast iron where CVD-coated carbide grades are recommended. The square insert shape and GM chipbreaker make it a standard selection for through-hole and blind-hole drilling on CNC machining centers and CNC lathes with live tooling. Minimum order quantity for this insert is 10 pieces; each package contains 1 piece.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is secured before seating or removing inserts. Use the appropriate Torx or hex key torque tool per the drill body manufacturer seat specification. Inspect the insert pocket for debris and damage before fitting a new insert, and confirm the cutting direction matches spindle rotation before resuming operation.
