Where can I get brushes for a Mastercraft corded angle grinder

SOURCE: Can't get grinder to turn on. Checked brushes. . .

Did you check continuity to the field/brush holders. They have a garter spring that sometimes became overheated and broke. It seems like you have done everything else. Let me know

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.

check inside for any loose connections plus check the brushes. if like you say it is smoking it could be a trip to the wheelie bin for that one.

SOURCE: angle grinder eats carbon brushes

Yes, the rock dust is what's destroying your brushes and armatures. It gets sucked into the rear vent slots and gets to those parts and eats them away quickly. I don't know of any vacuum systems make by Makita but there are some companies that make them for their systems. Blastrac is one that comes to mind but they can be real expensive systems. I don't know of any grinders with sealed brush/armature systems, they have too much heat to disipate. To make your Makita grinders last longer make sure you are cutting with the side of the blade that directs the dust away from the case and try to have a strong airflow blowing the dust away from the grinder to minimize the dust taken in at the back of the grinder.
