I have an Hitachi cordless drill 12v - DS12DVF3 - which I have lost the charger for. Yesterday I got a good deal on a 12v Ozito drill and the charger seems to fit the Hitachi battery, but I don't want to wreck it. Just because it fits and is the same voltage does that mean it's compatible? Should I use it? A genuine replacement charger for the Hitachi is far too expensive.

I understand how to attach the two that came with the drill. But I purchased a screwdriver and drilling set (Black and Decker) and there are all these different sizes of bits, but the ends are very skinny....way too small for my drill. I found a hex thingy-ma-jig in the kit that has the proper end to go into my drill. But, how the heck does the drill bit get attached to the hex? The bit end is very skinny. Now, the screwdriver bits fit just fine into the hex. What am I missing here?
Thanks for any help!
This is my first drill!!

I am a first time home buyer.... actually haven't even closed on the house yet. I have a little bit of construcion experience and feel pretty confident doing most home improvement jobs. In my new home I am planning to completely remodel a bathroom, finish the basement and possibly add a deck in the future. What should I look for in a cordless drill that will allow me to do a wide variety of projects. I will be needing to drill into pressure-treated decking, drive screws into drywall and cement board, and would like to be able to drill into cement a little bit to fasten studs.
So far I was looking at possibly getting an 18 V drill such as the Ryobi P203 which I saw was rate very highly by Popular Mechanics:

I also wouldn't mind a package with multiple power tools

I am also wondering how effective a drill like that would be for drilling into cement (I won't require much drilling into cement). Do I really need a hammer drill?

Any advice would be appreciated... what would be good for my projects?

I didn't think we had storage of electricity down yet. If we did, why do most people need to buy a new cordless drill, cell phone, or car battery every 5 years? The chevy volt battery will cost around ,000 to replace. Shouldn't we invent a better way of storing electricity before we start inventing things that run on it? I know they are currently inventing new forms of batteries all the time. They still need lots of work and development though.

I have been drilling sea glass w/ a special bit that I ordered especially for glass and it was working great no broken glass or bits but it appears to not be drilling and has broken 2 pcs. suddenly. Why?

like battery shelf life (Nimh batterys not ion) 18volt circ. saw drill and sawzaw. Any input would be nice because I have always owned dewalt or black and decker tools drills and saws

I have an old Makita cordless drill which has served well for general home usage. It is a model 6010D DC 7.2V 600rpm. Now, it is running so slow with no oomph. I am alone now and just need it for an occasional molley or curtain rod install. Could it be the battery or do I just have to purchase a whole new drill? The drill is probably 20 years old and the original battery has never been replaced but I hate to waste twenty-some dollars if the drill is just pooped. The charger light goes on when I plug the battery in and it does run, just very slow. I am not even sure I can get a battery any more. It says to use only Makita battery 7000.

Also, I am at a loss if I need to purchase a new cordless drill. I just need one for general occasional home usage. Nothing elaborate. If you can advise either way I will be grateful. What size drill and what is a respectable manufacturer or, stick with which size Makita?

Thanks, Donna

Okay, I cannot afford a good cordless drill, so now I am looking at electric (corded) drills. I'm sure that the same things apply to corded drills as to cordless drills. However, on corded drills it appears that the power is measured in amps rather than volts. How many amps do I need to drill through wood and seat crews without stripping them? I went to Lowe's and see that an 8 amp Dewalt corded drill is .00 dollars as compared to an 18 volt Dewalt which is approx. 0.00. I know corded is not as convenient as cordless, but my budget is .00, (so I also need to think about the cost of an indoor/outdoor extension cord.)
Okay, now I'm confused. Dan H says that his Ryobi and Black and Decker are used in daily construction, which I assume is pretty heavy and active use. However, other people are saying that Ryobi's and B&D's have plastic internal parts and won't hold up. Which info. is correct?

The batteries on my cordless drill are bad, replacement batteries cost as much as a whole new one, that seems so damn wasteful. Does anyone manufacture replacement batteries for cordless tools that are not so expensive?

I need to drill threw a 15mm piece of wood with a 6mm drill piece. I only have masonry drill bits. Is that okay?
