Long long story back to 1985' in use and buying the cordless. I prefer a pistol grip cordless powertool as per classically trained in use. 14.4V DeWalt has been my standard for - since they came out, because when it came time for me to be the buyer, they held a charge long enough and many more voltages were more popular for theft. 14.4v platiform had sufficient power and life to use them. DeWalt no longer supports most of the tools I have, and indeed when not doing something on the drill press, I want three to four drills to work with in pre-mounted bits. Totally over DeWalt as a brand in having bought the best 20V Lithium Ion hammer drill version I could get. Hate it’s chuck, this much less it is not pistol grip. Beyond that, it’s blade lock is of the gears holding motor verses bit tightened into clutch. Way too much movement in motor/gears slipping/stripping so as to get a in theory tight drill bit. Never felt the gears of a motor slipping between them before this drill. Chuck of a non-ratcheting design that will burn your hands before you get the bit tight enough if using your hands to tension a bit. I have rejected this drill in giving it to one of my assistants. TBA when gear teeth wear out or given the bad chuck are a problem also for him more modern than I in wanting to go 20V Lithium Ion. I hated the DeWalt, but my DeWalt 14.4v inventory is getting old - this especially for drills I constantly work with. The next upgrade is necessary, glad I fought such "modern" 18v and other "upgrades" this long in not having to deal with theft or heavier but not better tools. What brand / model to look into given I want hammer drill and impact drivers of the same battery once I switch? Money for the next tools is not an issue given I find one that will serve me for the next 20 years. Brand given I dislike the DeWalt also now open. Believe 20v Lithium Ion to be the next current standard that will hold for the next couple of years. Theft isn't a problem for now given personal vs. shop 14.4v tools especially after personal department staff tools in 14.4v are put into shop tool inventory. I want a good Pistol Grip tool, but recognize that age is probably gone. My guys are all T-handle drill. What's best for me will determine what the get. We do hammer drill but also the impact drill, so both platforms are necessary. Help here in choosing a product?
