tool steel
Definition
Noun: - A type of alloy steel: A specific category of steel that has been alloyed with other elements to achieve properties that make it suitable for manufacturing tools. Its defining characteristics are hardness, toughness, and the ability to retain a sharp cutting edge.
Usage
Tool steel is used to make tools that cut, shape, or form materials. It is not typically used for structural components. - Drill bits, milling cutters, and taps are often made from tool steel. - The durability of a good chisel depends on the quality of the tool steel from which it is forged.
Advanced Usage
- Specific grades: Tool steel is often referred to by specific grade designations (e.g., D2, A2, M2, O1) which indicate its precise chemical composition and heat treatment, defining its optimal use.
- For high-wear applications, a machinist might select D2 tool steel.
Variants and Related Words
- High-speed steel (HSS): A subclass of tool steel alloyed to withstand high temperatures generated during high-speed cutting operations.
- The lathe tool uses a bit made of high-speed steel.
Synonyms
- Alloy tool steel: A more technical synonym emphasizing its alloyed nature.
- Cutting steel: A descriptive term highlighting one of its primary functions.
Noun
-
