Cordless drills are great tools to work with but when you need to make big holes in concrete, 120 Volts corded Hammer Drills are required. With its switch-hitter feature, you can convert it from hammer to non-hammer mode which gives you the capability of making holes in concrete or wood with great ease. You might think that this tool will be expensive and is only meant for contractors but its not.

Review: Milwaukee is very powerful, long and heavy and due to its structure and configuration, it is considered as a industrial tool. It has a very powerful speed motor just like a jet engine. This is a perfect tool to bore big and small holes.
