Tool grinders and sharpening machines are specialized resurfacing machines for tool, die, punch, cutter, blade and drill point sharpening, as well as general grinding, honing, finishing, resharpening, refinishing or regrinding. These machines will recondition cutting and incising tools to full design specifications to maintain a usable profile. They can also provide engineering assistance for specialty cutting applications. Tools that are manufactured or reconditioned include end mills and other milling cutters, drills, turning and boring tools, broaches, form tools, burrs, counterbores and countersinks, and other specialty cutting tools for materials such as high-speed steel, different carbide grades, and industrial diamond or diamond coatings.
