Free cutting steels are a group of steels that are specifically designed to be easy to machine or cut. They contain sulfur, lead, and other elements that help to reduce the amount of force needed to cut through the steel. This makes them ideal for use in manufacturing processes where a lot of cutting or machining is required. Some common examples of free cutting steels include 12L14, 1144, and 1215.
