    I've had to fix my AEG angle grinder 3 times! One time the motor brushes wore out and I had to modify some to fit. Another time a motor bearing collapsed. The other thing was the switch, it was a 2 pole switch but one pole failed so I bypassed it and use it on one pole. I use the diamond discs which don't shatter.

    I had one of these kick on me. It had cutting disk and no guard it really was a hand grinder.

    I would have ground down the welds and separated it then reweld it.

    Not using the guard with a cut-off wheel, i laid my pointer finger wide open at the knuckle when the grinder kicked back and did a 360 flip in the air before landing on my knuckle. I was told to ggo get stitches but I chose to use butterfly bandages instead. Healed good with a scare line and hurts when weather is cold. But otherwise everything is all good😄👍

    The guard is literally in the way all the time.

    Should be using faceshield and gloves anyway.
    I have a curtain set up to keep it off of everything and ambient dust collection too.

    Loctite….?
    OK. 😐

    And why do people insist on insane amounts of oil, WD40, loctite, CARB CLEANER, every time.

    That's a perfect situation for a tig torch and no filler rod

    When you have a different disc thickness your supposed to flip the lock nut to have more threads on it

    That's why they have two hand holds as well as a discharge shield to keep folks safe but if things are seriously going to go wrong that should isnt going to be much help in preventing and the shields intent was grinder stones shattering at speed or breakdown
