Hi Guys I am looking to buy a drill for DIY and moding so I need one that can do it all Concrete (hammer drill), wood and Metal. So needs to be veri speed and able to turn off hammering and still have the RPM to drill metal. I am having trouble finding any webpage that does in depth tech reviews of this type of tools. Can some one point me in the right direction? Budget is around £100 pounds but only for a high quality unit with at least 2 year warranty.
