This set is the smaller version of the AOA-30S1, it comes with a large variety of sockets and is better suited to general applications. If you are interested in the larger set for heavy-duty applications, check it out here. This unique tool from Anex has a brilliant design that allows you to fasten nuts and bolts with an impact driver or drill where only a hand spanner would usually fit. It can be driven by a 19mm socket or the 1/4" shaft of any standard bit and is suitable for heavy duty applications with a massive 180Nm torque rating. This set comes with a range of sockets for multiple applications as well as a "Gear Lock", which stops the gears from spinning, making it function as an ordinary spanner when hand tightening is enough. The accompanying carry case keeps everything nice and organised.
