The WORX WX354 Slammer Drill, is more than a standard combi or hammer drill. With a standard combi (hammer) drill, you can drill into masonry, but never into concrete.
With an SDS hammer drill, you can drill in masonry and concrete, but these types of tools are not as suited to drill in softer materials such as wood or metal.
The WORX Slammer Drill drills into wood, metal, plastic, masonry and even concrete! This kit comes complete with 2x 20V POWERSHARE™ 2.0Ah Batteries & 1x 2A Charger that will also power all other 20V cordless WORX tools.
