I currently have dewalt 18v combo drill and impact wrench with 4ah batteries, the company i work for supply a 36v gbh sds drill, the charger is huge and takes up a lot of space in my ds400 tough system box. i was wondering if anyone has experience with both these drill as i would like to replace the bosch with a dewalt, is the dewalt significantly underpowered compared to the bosch? many thanks john
