Wera 39 piece tool set includes a selection of tools that provides an incredible 162 tool combinations from a very compact storage case. The ultra strong, fine action 60 tooth, 6 Bit Ratchet will take well in excess of 65 Nm of torque, but will drive bits within a 25mm working space - ideal for confined places where screwdrivers and power tools cannot be used. A knurled collar allows finger turning action of the ratchet mechanism. The 1/4" hex x 1/4" square drive adaptor converts the ratchet to drive the sockets. The Kraftform bit holding handle will accept all of the bits and with the adaptor, also drive the sockets. The inclusion of the Rapidaptor 1/4" bit holder allows the bits and sockets to be driven by a power tool and double up as an extension for the ratchet and Kraftform handle. The Kraftform multi-component handle is designed to deliver extra comfort during intensive use, especially when high torque is being transferred.
