Holder for a Hitachi 14.4V drill and its accessories. The model is called DS14DBL(HW). It came as a complete kit with two batteries, quickcharger, a grip and the drill bit. The drill holder can also be used as a robust battery sheath if you need an easily replaceable sheath you don't have to worry about losing.
It is intended to be screwed onto a metal board with a 12x12mm hole spacing. The holes are 4.6mm and the screw head is approximately 9mm in diameter. However, it can also be easily mounted directly on a wall.
