Duratrax 12-tip multi-driver tool

The Duratrax 12-tip multi-driver tool stores six double-ended tool bits in the handle and does the work of a dozen different drivers with just one handy tool. The machined, anodized aluminum handle is hex-shaped to resist rolling and improve grip. The end cap rotates to select the preferred bit. Bit length is adjustable, so the modeler can shorten it for more torque or lengthen it for greater reach.
