There are various units that express the properties of metal materials, and it is important to check their numerical values before processing metal materials.
It is also important to select a cutting tool that matches the hardness of the workpiece material.
Among steel materials, the units of materials to be processed by taps and drills include HRC, which represents the hardness of relati
