High Torque Cordless Impact Wrench 3/4 Inch

Heavy Equipment Fastening Power, Sized for the Toughest Bolts

When fastening tasks move beyond automotive and into heavy equipment, agricultural machinery, and structural connections, the 1/2-inch impact wrench class runs out of capability. Our high torque cordless impact wrench with 3/4-inch square drive delivers 1,400 Nm of maximum fastening torque and 1,900 Nm of nut-busting breakaway torque from a 60V battery system, putting genuinely industrial fastening power into a tool that doesn't require an air compressor, hose reel, or fixed power connection. The dual-hammer impact mechanism distributes striking force more evenly across the anvil than single-hammer designs, reducing reaction torque felt at the operator's wrist while delivering more consistent energy transfer to the fastener.

Four selectable power modes allow precise matching of output to the fastening task: a precision mode for delicate aluminum components, two intermediate modes for general heavy fastening, and a maximum mode reserved for breaking severely corroded or over-torqued fasteners. An additional reverse-assist mode automatically pulses at reduced power during reverse rotation, preventing the fastener from spinning off too aggressively and falling into machinery housings or hard-to-reach locations during removal.

The 3/4-inch anvil accepts heavy-duty impact sockets rated for the torque output this tool generates — a critical compatibility note, as standard hand-tool sockets are not rated for sustained impact loading at this force level and can shatter under use. A friction ring retention system holds sockets securely during overhead or vertical work, reducing the risk of socket drop during equipment maintenance at height. The 60V battery platform, while requiring a dedicated charger system separate from smaller-voltage tools, delivers the sustained current draw necessary for repeated high-torque impacts without voltage sag mid-fastening cycle.

Built for heavy equipment technicians, structural steel crews, and mining and quarry maintenance teams, this impact wrench is engineered for an environment where fastener sizes regularly exceed what consumer-grade tools can address. The reinforced gear case and impact mechanism are rated for continuous industrial duty cycles, and the brushless motor eliminates the maintenance interval that brushed motors require under this level of sustained torque output. For fastening tasks where 1/2-inch tools simply cannot generate sufficient torque, this 3/4-inch wrench delivers the power heavy machinery demands.
