Nothing but heavy duty....Thats Milwaukes strap line and its so very true. these two tools will complete any job you are planning with ease. A really strong and powerful comination drill together with an amazing impact driver make this set a must-have for anyone. A 3-year warantee on the drill and a 2-year warantee on the batteries is available on registration which, in itself, is quite amazing given that a lithium Ion battery will never last more that 3 years wherever you buy it.
