Draper Air Impact Wrench With Composite Body, 1/2" Sq. Dr.

Low-Noise, Low-Vibration Impact Power for Workshop and Mobile Use

The Draper DAT-AI12 is a 1/2" square drive air impact wrench designed for mechanics, fitters, and serious home users who want serious fastener-shifting performance without the harshness of older all-metal impact tools. Built around a composite plastic body and a high-tech three-speed reversible motor, it offers low noise, low vibration, and a comfortable in-hand feel — while still delivering an ultimate torque of 340Nm (250ft/lb) for stubborn nuts and bolts.

Composite Body for Lower Weight and Better Comfort

The DAT-AI12 is housed in a casing made from composite plastics, a construction choice that brings several practical benefits. It keeps the tool's weight down to just 1.8kg, making it noticeably easier to handle than heavier all-metal alternatives — particularly when working in awkward positions or for extended periods. The composite body also helps to reduce vibration transferred to the user, which is reflected in the modest 3.3m/s² vibration level. Just as importantly, composite construction helps to minimise 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.

Three-Speed Reversible Motor with Powerful Rocking Dog

The wrench is fitted with a high-tech three-speed reversible motor, giving you a forward/reverse selector and the ability to match power output to the task in hand. A powerful rocking dog impact mechanism delivers the percussive blows needed to shift seized fasteners, with an ultimate torque rating of 340Nm (250ft/lb) — ample for the majority of automotive and general workshop fastener work. Free speed is rated at 7,500rpm.

Comfortable, Considered Ergonomics

Lightweight construction, balanced design, and the cold-sink-reducing benefits of the composite body combine to make the DAT-AI12 a comfortable tool to use through a long list of fasteners. Lower noise output also makes it easier to live with in busy workshops where multiple tools may be running at the same time — a small detail that pays back across a working day.

Sensible Air Requirements

With an operating pressure of 90psi (6.2bar) and an average air consumption of 4.0cfm (114L/min), the DAT-AI12 is well-matched to mid-sized 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.
