    Dewalt 11amp angle grinder o-ring

    There is an o-ring on the arbor that i think holds the mandrel in place.

    Is this o ring important to maintain?

    Not really... until you drop the upper arbor washer while you're changing discs over an irrigation pond. Ask me how i know.

    Today I likely would have jumped in after it. It was hot. Most any other day I'd likely pitch grinder in the drink.

    It is only for the bit of retention it adds. Otherwise it is all there to function just like earlier ones that didn't utilize the orings on them.
