Anton there is a reason a drill gets hoter in reverse than in forward.
A drill is designed to go forward most of the time so there for the fan that cools the drill is designed to "suck" rather than "blow"
When the motor is ran in reverse for a long period of time the fan is unable to cool faster than when in forward.
The answer is to get a fan that has rotated fan blades.

: Okay here's the deal...

: we were playing with the drills and found out after intensly driving it for like 5 mins, that the left motor gets twice as hot as the right motor.

: in other words, the left motor which is the one that goes in reverse is heating up more than the one that goes forward.

: Question is: IS THIS NORMAL? i dont know if it's related to the reverse/forward mechanism....i didnt think so. my guess is that the left side is just creating more friction somewhere?

: what do you think? thanks..
