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