From: John Doe on 11 Aug 2010 15:36 Asking for a wild guess. How much power is lost between the motor and the chuck of a cordless drill? How much power is lost in the gearing? In other words... If you were to use the motor alone to directly drive something (fast), how much more efficient would that be than keeping the whole drill together and driving that something through the chuck (slowly)? Thanks. -- I say "cordless" just to make clear what I am talking about.

That's nice but doesn't answer the question. -- Jim Pennino Remove .spam.sux to reply.

He is trying to make a point, but we are supposed to state it first. Obviously, he is asking a leading question. There is an agenda here. His question isn't about curiosity. So I have to ask: 1) When did you stop beating your husband with a 36V Bosch cordless hammer? 2) Why didn't you try the Bosch 120 V corded hammer with the three way plug?

Wow, mind-boggling sentence you have there. > Obviously, he is asking a leading question. No, actually, my question was asked and (as far as I can tell) clearly answered.
