Hitachi Drill Driver

The Hackspace has two 'pairs' of Hitachi Cordless drills, also usable as power screwdrivers.

Model DS14DVC is a non-hammer drill with a maximum speed of 1250rpm

Model DV14DVC2 is a drill / hammer drill with a maximum speed of 1500rpm

All use the same 14.4v 1200mAh / 1500mAh rechargeable battery packs, and there are two 'intelligent' charger stations for these.

The hammer drill variants have a larger chuck capacity, and so can accommodate hole-saw arbors - this is particularly useful as these should be run at a particularly slow rotational speed and these cordless drills have speed control on the triggers.

Both types have low / high speed gearbox selection - use low speed for high-torque is needed (e.g. screwdriving) and high speed for drilling.

Damage can be done to the drills and battery packs if they are run too intensively. One drill and battery pack has been damaged in this way as the contacts between the two parts overheated, pressing the contact springs into the plastic bodies, where the plastic set in such a way that contact couldn't be made. Repairs are currently in progress (04:39, 15 February 2014 (EST)). In future, please pay attentions to any 'hot plastic' smells and give the drills a rest before continuing to prevent re-ocurrence.
