It seems you're asking about the of a product or system called "Master Tools Standard."

However, without a specific product context (e.g., a software suite, an industrial tool brand, a CNC machining package, or a standards document), I’ll provide the most common interpretations. In CAD/CAM software (especially Mastercam ), "Master Tools" refers to toolpath or tool management features. A "Standard" version typically includes core functionalities.
