Draper Air Impact Wrench, 3/4" Sq. Dr

Heavy-Duty 3/4" Drive Power for Serious Workshop Tasks

The Draper DAT-AIW34 is a heavy-duty 3/4" square drive air impact wrench built for mechanics, fitters, and commercial workshop users who need serious torque on tap for larger, more demanding fasteners. Delivering an ultimate torque of 1000Nm (740ft/lb) through a high-power twin hammer mechanism and a high-tech three-speed reversible motor, this is a wrench designed to tackle the kind of work that lighter 1/2" drive tools simply cannot handle.

3/4" Drive for Larger Fasteners

The step up to a 3/4" square drive is significant. It opens up a wider range of impact sockets for larger nuts and bolts — the kind found on light commercial vehicles, agricultural equipment, plant machinery, and heavier suspension and chassis components. Combined with the 1000Nm ultimate torque rating, the DAT-AIW34 has the muscle and the drive size to deal with fasteners well beyond the comfortable range of a 1/2" drive impact wrench.

High-Power Twin Hammer Mechanism

A high-power twin hammer impact mechanism delivers consistent, hard-hitting blows for shifting seized and corroded fasteners, while helping to reduce reaction torque felt by the user. The result is a tool that can keep working through a long list of stubborn fixings without leaving the operator fatigued by the kickback that often comes with single-hammer designs.

Three-Speed Reversible Motor

The wrench is fitted with a high-tech three-speed reversible motor, giving you adjustable 3-position power in forward and full power in reverse. The forward power adjustment lets you dial in torque to match the task — easing back when working on smaller or softer fasteners and stepping up to full strength for the toughest fixings. Full power in reverse means maximum effort exactly where you need it most: freeing stubborn, seized nuts and bolts. Free speed is rated at 7,000rpm.

Lightweight Aluminium Housing

The DAT-AIW34 is built around a lightweight aluminium housing, helping to keep the tool's weight to 3.0kg — manageable for a wrench delivering 1000Nm of torque. An ergonomic soft grip handle with a rubber protective grip adds comfort and control, making the tool noticeably easier to handle during prolonged use. The lightweight aluminium construction also helps to reduce the "cold-sink effect" — the chilling sensation common with air tools as expanding air cools the body of the wrench in the operator's hand.

Handle Exhaust for Cleaner Working

A handle exhaust routes spent air away from the work area and the user, helping to keep dust and debris from being blown around the immediate workspace. This is a practical detail for jobs like brake, hub, or underbody work where loose dust and rust particles can otherwise be an issue.

Sensible Air Requirements

With an operating pressure of 90psi (6.2bar) and an average air consumption of 6.5cfm (184L/min), the DAT-AIW34 is well-matched to mid-sized and larger workshop compressors. A 1/4" BSP air inlet makes for straightforward connection to standard workshop airline setups, with a minimum recommended hose size of 3/8" internal diameter to ensure the tool gets the air flow it needs to deliver full performance.

Ideal Applications

The Draper DAT-AIW34 is a strong fit for commercial vehicle servicing, larger wheel and tyre work, heavier suspension and chassis tasks, plant and agricultural machinery fastener work, truck and HGV maintenance, and any workshop application where a 1/2" drive impact wrench would be undersized for the fasteners involved. The 1000Nm torque rating and 3/4" drive put it firmly into commercial workshop territory.

Backed by the trusted Draper Tools name, the DAT-AIW34 combines twin hammer power, 1000Nm torque, and a 3/4" drive in a well-balanced lightweight aluminium build — a serious tool for serious workshop tasks that demand more than a standard 1/2" drive impact wrench can offer.
