These wheels are used with hand-held flex-shaft or micromotor rotary tools. Jewelers and hand engravers with experience sharpening gravers use these tools to hand-sharpen gravers. These are usually used under a microscope or other forms of magnification.
The Green wheel is used to shape tools. For larger gravers or gravers made from carbide steel, people frequently use diamond wheels to rough out the graver and the green wheel to refine a shape.
The Blue wheel is for further refining a shape and putting an initial edge on a tool.
The Yellow wheel further sharpens and polishes a tool.
Each wheel is also sold individually.
