The drive is powered by a 72-tooth inner ring made of high-alloy special steel, even with a lever movement of just 5 degrees. Nevertheless, the transferable torque values far exceed the DIN/ISO specifications. The shafts are made of CrV steel and provide optimal surface protection: nickel-plated twice and matte chrome-plated once. The sizes are clearly readable due to a laser marking process. With a ratchet function on the ring side, it allows for time-saving work without repositioning. Ideal for "inserting" into tight spaces, suitable for engine removal and installation, on automatic transmissions, on rear axles, and much more.
