hi guys, I wanted to build a bicycle powered by 4 cordless drill machines and was wondering if their rotation speed is the same in both the direction, clockwise as well as anti-clockwise. the drills i plan to use are the Bosch GSB 18v-LI professional. any information will be really appreciated.
any information on their rpm.

I have no preference because this is my first power tool. I have heard great reviews about both, just don't know which one to chose.

What kind of drill do I need to easily drill holes into the cement sub-floor of my house (for a flooring project)? I've already tried two different types of masonry bits with my cordless, 18 volt Bosch (model 3850). I'm thinking that the bit isn't the problem, it's the drill. It takes about 10 minutes and a way too much effort just to drill one hole. Any suggestions?

I just bought a Bosch 18V Cordless drill and bought a 14 piece set of Milwaukee drill bits and was wondering how the 1/16 to 5/32 fit? Doesnt seem like they can go down to the very bottom, is their an adaptor you buy or what?
cool, thanks.

I have a Bosch 12V cordless drill. The drill came with 2 batteries. Both batteries have not been holding a charge.
I have the choices of buying new batteries @- each, Have Batteries Plus rebuild the batteries for each.
Or trash the drill and buy a new 14V for around 0.Do you have anyother ideas? Which choice would you go for.
P.S. I do like this drill.

I do not have enough money to be upgrading from decent quality tools to great quality tools, so this is why I'am trying to find some of the best tools out their..I'am going to be starting woodworking classes and want some good quality tools are these very good or not?

Also, how long do you think these tools could last if properly cared for and used 2-3 times a week or something like that,Thanks!

My cordless drill Bosch 12V comes with two batteries so I can be recharging one while you use the other. But actually both of them do not hold a charge between uses. I know that many people who have cordless drills buy new batteries and it cost them about - each. But I've also been thinking about rebuilding both batteries for each. Or I may just throw my cordless drill away and find a new cordless drill for sale. I may buy a new 14V.
What do you think?
