If I was you I would go for an Hitachi 12 or 14 volt, the gearing on them is greatm Draper is not a very good drill, I have an 18volt and a 24 volt De walt and they are superb drills, but if I was going for a slightly lower voltage it would be Hitachi, in fact the 14 volt is every bit as good if not better than my 18 volt, you will not lose power going for one of these, a lot also goes on the battery A/H that needs to be 2 or above a lot of the cheaper ones are 1.2 or thereabouts, good luck, Ray
