Why this one
Fine-arc 72 tooth mechanism
The ratchet head delivers a 5-degree sweep arc, letting you drive fasteners in tight spaces where a quarter turn is all you have.
Telescoping handle for maximum leverage
Instead of grabbing a separate pipe or switching to a breaker bar, extend the handle from 545 mm (21.5 inches) to 860 mm (33.9 inches) and apply the torque you need.
Chrome vanadium construction
Built from chrome vanadium for the toughness that high-torque 3/4 inch drive work requires.
DIN 3122 compliance
Manufactured to the DIN 3122 standard for ratchets, ensuring consistent quality in tooth engagement, head geometry, and overall durability.
TTX4 tray for organized storage
The 2-piece set ships in a molded TTX4-size tray that fits directly into Teng Tools roller cabinets and tool-box systems.
Read the full description
When the fastener calls for serious torque, you need a tool built for the task. This 3/4 inch drive set pairs a ratchet wrench head with a telescoping handle that adjusts from 545 mm (21.5 inches) to 860 mm (33.9 inches), giving you compact maneuverability or full-length leverage without switching tools.
The head uses a fine-arc mechanism that requires only a 5-degree sweep to engage the next tooth, so you can keep working in confined spaces where swing room is limited. Chrome vanadium construction handles the repeated high-load cycles that 3/4 inch drive applications demand, from axle nuts to heavy suspension work.
Manufactured to DIN 3122, this tool meets a recognized engineering standard for dimensional accuracy and mechanical performance. The set arrives in a shaped TTX4 tool tray that drops straight into compatible Teng Tools storage systems, keeping both pieces organized and accounted for. At 4766 g (10.5 lb) total, the tray is ready to slide into your cabinet or travel to the job site.
Whether you maintain a fleet, service heavy equipment, or handle industrial fasteners daily, this 2-piece set delivers the reach and precision that professional 3/4 inch drive work requires.
