I have 3 dewalt 14.4 drills that I have used in the installation of CVS pharmacys since 95. Before that I had 6 dewalt 12 volt drills that are still going strong other than the batteries are getting old and new ones are hard to find. They just keep on working. Had a lot of people ask why I had so many drills but when you need to get the job done quick you just put different bits in each one and you don't have to keep changing bits just grab the right drill.
