The only difference between a battery drill and a regular drill is the type of power source. A battery drill is one that does not require a power cord, but can only last a finite amount of time.
Special Direct System drills are heavier than regular drills, have a hammer action and a chiselling action and take larger drill bits and chisels.
There is no difference, I drill both frequently with the same drill bits.
metal drill bit has a finer point
Mainly that one is a drill, and the other, a screwdriver.
That's a tough task for a battery operated tool. You really need a hammer drill. There's a nice Milwaukee cordless hammer drill at Sears but it costs $350. My corded hammer drill cost only $79. To me that is a huge difference for the convenience of cordless.
The 3/8 drill is one eighth larger.
You can't, you need to get a replacement battery for the drill.
Those are just different names for basically the same thing.
The SDS drill is considered to be the superior option for efficiency and ease of use, it does not require a chuck key. The hammer drill requires a chuck key for fitting different drill bits, which is considered the main difference of the drills.
Unfortunately, no. You'll need a 12v battery for the drill or a 14 v drill for the battery.
