If you need both a hammer drill and an impact wrench, you can't beat this set from Worx. I've seen similar kits from Dewalt sold for double the price, but the Worx tools are just as good in my opinion. If, like me, you already have other 20V Worx tools, the batteries are interchangeable. This is an added benefit as I can use these drills all day without running out of power since I have so many 20 volt batteries. Although this rotary and percussion drill hammer is very powerful, it is also more compact than comparable models from other manufacturers. So you can use them in tight spaces and hold them longer without hand fatigue. Worx is a brand that I have no hesitation in recommending. Of the many Worx tools I own, none have let me down or disappointed.
