Dewalt 4.5 inch angle grinder is blowing fuses

Some of those double insulated power tools have a remote switch. By remote I mean that the piece you push, or pull does not actually have a switch on it, but has an arm or rod that could be several inches long, and that arm or rod actuates the switch.

If that 'arm' which is usually plastic breaks, the unit won't turn on (or in some cases off)

I have had a Dremel tool and a haircutting clippers that did exactly what you describel

Make sure it is not plugged in, then remove the phillips screws holding it together. Many times there is one hidden and you have to look for it.

Gently -- Gently separate the two pieces of the body. I like to do this over a white beach towel so that any pieces that might jump out at me won't go far and be easy to spot on a white background.

Look for an arm that reaches towards a switch --if it is broken it will be obvious.

I repair that kind of break with JB Weld. Don't get the quick dry JB, but the 'normal' product. Quick dry gives you almost no 'open' time.

Just mix a tiny dab of material from each tube together on something non-porous e.g. a piece of scrap ceramic tile, broken dish, glass, mirror and put a little of the mixture on each part of the broken area.

Put the two pieces together and let dry -- for 24 hours.

Re-assemble and you are home free!

I always have a plan for clamping or propping the repaired part so that it won't move BEFORE I mix the epoxy. That way I am not scampering around trying to find what I need whilst trying to hold it together.

Many times I use a tiny screwdriver and dip it into the mixture and apply it with the screwdriver. As long as you wipe the screwdriver clean with a paper towel it will be fine.

good luck.

could be worn brushes a shorted armature or field issue. check the brushes first and the commutator would need to be cleaned to seat the new ones. that is the cheapest route.
