S2 Metal
S2 metal is thought for its toughness and put on resistance. It’s a higher choice in case you want a bit that may stand up to high-torque functions and heavy use.
Warmth Therapy and Hardness
These processes improve the energy and sturdiness of the metal. Warmth therapy is used to harden the metal, and the hardness is measured on the Rockwell scale.
Sizing and Compatibility
Selecting the best measurement is important for stopping harm to screws and supplies. Every bit kind is available in completely different sizes, every designed to suit particular screw head sizes.
