I bought a new 18v cordless drill (craftsman) from sears, and I happened to test it in a dark room. I found a mass of electric sparks gernerated inside the drill every time I run it. I could see the electric sparks through its air vents, and the obvious electirc sparks even illuminated the nearby stuff when I put in the reverse gear, no kidding, it looked like a small bulb was installed there.
Could anybody here please tell me if that was normal for a cordless drill? The electirc sparks really scared me, they could make a big problem in some circumstances.
Thanks.
