I'm not sure if this has been discussed before, but I wanted to reopen the issue with some of the newer drills on the market, and pose some specific questions. I did not want to make this a poll because I think this topic should be more of a discussion than a yes or no answer. I'd like us to take some time to compare and contrast a "Driver" (or "Screwgun") with a Hammer Driver and Impact driver. We are talking specifically about cordless models here, and trying not to break down into brand and battery voltage bickering. A little background definition to make sure we are all on the same page. My understanding of the three are as follows, I'm sure some of this is wrong, so please correct, and mods feel free to edit this with accurate information. Driver ("Screwgun") Your traditional tool for driving a screw. Cheaper. Lighter Duty. Most likely lighter. Most likely less power consumption. Hammer Driver Heavy duty. Used for driving screws into stone or other "brittle" (but strong) material. This physically pushes forward the drill bit, smashing it's way through concrete etc. Likely heavier, costs, more, more breakable parts, etc. Often has setting for "No Hammer" and "Hammer". Impact Driver More expensive than standard driver. Claim to fame is that the "forward impact" motion, similar to the Hammer Driver, instead forces a sharp turn "around 90º. This causes the Impact Driver to deliver more foot pounds of torque than it's competition. The other benefit of this driver is that it is traditionally smaller than a standard driver. Doesn't strip screws. So I have been working along side a guy who recently picked up the Makita Li-Ion impact driver. He loves it. I know little on the subject, but it seems like the impact driver is the way to go. I have been considering buying some sort of driver, so that is my current plan.
