My drill just stopped working the other day. There is power going to the drill but nothing happening. The windings are OK. It's like the trigger is just dead.

I have a Dewalt DW566 Type 1 Rotary Hammer. While drilling a hole and pulling it back, the nose came off, complete with the washers and spring. Trying to replace it back, it won't seat right and the bit won't stay in. Is there a trick to this? Or do I need a new reataining washer?

Hi
New to this type of forum. I have DW566 type 3 drill which packed up on me. I replaced the worn out bushes and the drill now works but there is a lot of intense sparking and burning smell from around the bushes which I think caused the first lot of bushes to go. I presume the fault could be the armature or the field coil. Would this be a fair assumption and if so any educated guesses as to which one to try replacing first. Thanks in anticipation.

There is some spark near the brush and have sound of " Pop Pop" when I use it, is it the problem of motor or the capacitor?
Is it danger for me to continute to use without repair?
