This invention relates to an improvement in cutters or tools for milling iron, steel, brass, or any other metal, and also wood, ivory, and other materials; and the invention consists in constructing the cutter out of two parts, which when put together, are separated from each other by an oblique plane in such a manner that when the tool wears off, or whenever it may be desirable, it can be adjusted by interposing between the two parts disks of paper or sheet metal, and a cutter is obtained which can be used for milling slots or grooves of different width, or which can be used for a long time in milling slots or grooves of a uniform width.
