I love them for work, bloody handy. We used the small (not sure what they're called) plug in 8th inch ones at work in Sarina. I loved the dewalts, they were tough, did a lot of work & weren't looked after. We dropped them from ladders or out of buckets, there'd work all day in the rain or during the wet, we'd unknowingly leave them in a puddle of water in the bottom of the bucket for a night or the weekend & they'd still go for us when we needed. The only reason we went away from the to Milwaukee, which were ok at the time, was there were no repairers for Dewalt in Australia.
Now in Roma, we have a half inch job that's on its way out. It's not that old, 18mths-2yrs but it's done an unbelievable amount of work. Before I got here, the boys got it to replace the hydraulic rattle gun so we wouldn't have the hoses flopping about. This thing regularly drills 26mm holes through big hardwood poles. After my doubts from Sarina, I want one for home, they'd last a life time here.
