Draper Air Impact Wrench, 1" Sq. Dr

Industrial-Grade Power for Truck, Plant, and Heavy Machinery Work

The Draper DAT-AIW1 is a serious 1" square drive air impact wrench engineered for commercial workshops, HGV fitters, plant engineers, and heavy machinery technicians who need real industrial-grade torque on tap. With a pinless hammer mechanism delivering an ultimate torque of 2,200Nm (1,620ft/lb), this is a tool built for the kind of high-volume repair work that would quickly overwhelm lighter 1/2" or 3/4" drive wrenches.

Pinless Hammer Mechanism for Sustained High-Volume Work

The DAT-AIW1 is fitted with a pinless hammer impact mechanism — a design specifically chosen for high-volume repair work on trucks, buses, agricultural machinery, and other heavy plant. The pinless construction is engineered for sustained performance under repeated heavy use, helping to deliver consistent torque output session after session in demanding commercial environments. It's the configuration favoured where uptime matters and fasteners are big, plentiful, and stubborn.

1" Drive for the Heaviest Fasteners

The step up to a 1" square drive opens up the full range of heavy-duty impact sockets needed for HGV wheel nuts, truck and bus axle work, plant and agricultural fasteners, and large industrial fixings. Combined with the 2,200Nm (1,620ft/lb) torque rating, the DAT-AIW1 has both the drive size and the muscle to handle fasteners well beyond the reach of smaller impact wrenches.

Three-Speed Reversible Motor with Power Regulator

A high-tech three-speed reversible motor gives you adjustable 3-position power in both forward and reverse — useful flexibility on a tool of this output, letting you ease back when controlled torque is required and unleash full power for seized or heavily corroded fixings. Free speed is rated at 3,900rpm, the deliberate lower-RPM profile typical of high-torque industrial impact wrenches.

Heavy-Duty Construction with Considered Ergonomics

The DAT-AIW1 is manufactured from heavy-duty materials throughout, built to withstand the demands of daily commercial workshop use. At 12.70kg this is a substantial tool — as you'd expect from a wrench delivering this level of torque — but Draper has paid attention to making it manageable in the hand. An ergonomic soft grip handle and a removable side handle work together to provide excellent control and comfort during prolonged use. The side handle is particularly valuable on a tool of this size and power, helping the operator manage reaction torque and stabilise the wrench during longer fastener sequences.

Side Exhaust Routes Air Away from the Work

A side exhaust port directs spent air away from the immediate work area, helping to keep dust and debris from being blown around as you work. This is a practical detail for hub, brake, and underbody work where loose particles can otherwise become an issue.

Industrial Air Requirements

The DAT-AIW1 is genuinely industrial-class in its air demand. With an operating pressure of 90psi (6.2bar) and an average air consumption of 40cfm (1,132L/min), this wrench requires a sizeable compressor to deliver full performance — something to plan for if you're specifying a tool of this output. A 1/2" BSP air inlet (not the more common 1/4" BSP found on smaller wrenches) connects to heavier-duty airline setups, with a minimum recommended hose size of 1/2" (13mm) to keep up with the tool's flow requirements.

Ideal Applications

The Draper DAT-AIW1 is purpose-built for commercial and industrial environments — HGV and bus servicing, truck wheel and axle work, plant and construction machinery maintenance, agricultural equipment repair, heavy fleet servicing, and any high-volume workshop application where 1/2" and 3/4" drive wrenches simply cannot deliver enough torque or drive size. The 2,200Nm torque rating and 1" drive put this firmly into industrial workshop territory, with the air supply, hose size, and operator stamina to match.

Backed by the trusted Draper Tools name, the DAT-AIW1 combines pinless hammer durability, 2,200Nm of torque, and serious 1" drive capability in one heavy-duty industrial air impact wrench — a confident choice for commercial workshops that put their tools through serious daily work.
