Feature

Construction & Technical Features

  • High-Leverage Drive Tools: The 500mm Ratchet Handle provides a massive moment arm, allowing the technician to apply the significant force required for 50mm and 2″ fasteners.
  • Flexible Handle (Breaker Bar): The 475mm Flex Handle features a heat-treated pivot head, specifically included to protect the Ratchet Handle from damage when “breaking” the initial seal of high-torque bolts.
  • Industrial Finish: Mirror-polished Chrome Vanadium (Cr-V) steel offers professional-grade corrosion resistance and easy cleanup after exposure to heavy grease and oil.
  • Reinforced Steel Metal Case: Given the total weight of a 3/4″ drive set (reaching up to 50mm), the heavy-gauge steel case is essential for secure transport and permanent tool organization.
