DEWALT BATTERY DRILLS & TOOLS
I use Dewalt tools virtually everyday at work, they have a vast range of battery powered tools on the market, and if like me , you may need to use several tools to complete one project, it is handy to have batteries which are interchangeable between the tools so you are not sat around waiting for a particular battery to recharge.
Dewalt battery drills come with many useful features such as variable torque, variable speed, hammer action or SDS, drill only, hammer only (for chasing out) and key-less chucks. They are powered by batteries ranging from 12volts to 36volts.
Dewalt have developed new, more powerful and longer lasting batteries for their battery tool range, the new lithium ion XRP batteries will recharge twice as many times (around 2000 times) as existing batteries before there is any reduction in power and run time. The batteries I use are Nickel-metal-hydride (NiMH) and normally last around two years before I replace them, bearing in mind that I use my Dewalt battery tools constantly, the new battery range should last a long time, especially if the tools are used for DIY projects only.
If I had to recommend a battery drill, either as a gift or to purchase yourself for general DIY projects around the home, I would go for either a Dewalt 14.4volt (DCD935L2) or the 18volt model (DCD925B2) both come with hammer action, variable speed, torque control and are powered with a XRP Lithium ion battery.
