The Busch High Grade Corundum Abrasive Wheel Shape 624 Ø6.0mm is a premium-quality mounted abrasive designed for precision grinding, smoothing, deburring, and pre-polishing of medium-hard metal alloys used in jewelry manufacturing, goldsmithing, silversmithing, and precision metalworking.

Manufactured from high-purity pink aluminium oxide (Al₂O₃), this abrasive wheel offers excellent cutting performance, long service life, and consistent material removal.

The medium grit size combined with a medium bonding hardness provides the ideal balance between cutting efficiency and surface finish, making it suitable for shaping, refining, and preparing metal surfaces prior to polishing.

Shape 624 is particularly suited for smoothing flat surfaces, refining castings, deburring edges, and preparing jewelery components for final polishing. The cylindrical design provides excellent control and uniform material removal on medium-hard metal alloys.
