Simply snap the Hex Driver into any standard cordless rattle guns or drill chuck. This is a common size used with caravans for winding stabeliser legs and other accessories. The 19mm Hex Driver is of medium strength for normal use. Not intended for use with extremely tough terrain or with high torque drills/rattle guns.
If you go camping on really hard compact ground and you’re finding it almost impossible to drive your GroundGrabba Pro into the ground then try pre-drilling the ground using the masonry drill bit. You may need to drill the ground an inch or two at a time and keep clearing the hole if the ground is ‘that’ hard.
