Three-speed T-handle ratchet wrench with a three-stage gear drive offers fast, efficient ratcheting, specifically designed for faucets. - Compatibility: works with tools that have a square shank, including left-handed thread taps, reamers, screw extractors, and other square-drive accessories. - Durability and size: chrome-plated surface for high durability; suitable for thread taps from M3 to M8. - Easy to use: easy to operate or can be locked to switch from left- to right-handed operation for non-ratcheting use. Use scenarios: - Installing or loosening faucet fittings in tight under-sink spaces where quick ratcheting saves time. - Removing stuck screws or extracting damaged fasteners with screw extractors that use a square drive. - Working with left-handed thread components, such as left-handed taps or reamers in the M3–M8 range, in a controlled, reliable drive.
