Flat Carbide Gravers by Tuna are made for use with pneumatic graver machines and are compatible with GRS brand machines (i.e. GraverMax).
Being harder than regular steel gravers, carbide gravers have become favorite tool for stone setters, engravers, and the like due to their ability to keep a sharp edge for longer as well as the various materials they can be used on.
For best results, it is recommended to use Diamond Rubber Polishing Wheels to shape, sharpen, and polish any carbide graver when maintenance is eventually required.
