Dont cange rotation? Id be grateful for aproper technical explanation for
this.

I do that regularly and it doesnt effect the life ofc the brush, in fact
it extends the life. you get more work done this way.
Read my last post on brush usage.
Could it be that as you sell these youve a vested interest in seeing the
brushes last as little as possible?
Its not meant as a chriticism just an normal engineering question.

I've found the best way to sell more brushes is to just keep my mouth shut!

If you're reversing a brush, it is not the right brush, speed, alloy, HP or
trim...take you pick of one or more. If the wire is laying over by more
than a couple of degrees, something is wrong. Engineers sometimes spend
weeks with clients analyzing an industrial application to match all the
variables. On the other hand, for general shop use the cost is no real
concern and no brush manufacturer makes any money on that family of
products.
