T1 high speed steel is a type of tool steel with a high tungsten content, which allows it to be extremely hard and resilient under high temperatures. It is commonly used in cutting tools such as drills, taps, and milling cutters, as well as in manufacturing metal forming tools and dies. The hardness and wear resistance of T1 steel makes it ideal for machining tough materials such as stainless steel, high-temperature alloys, and cast iron.
