Question about Black & Decker 9"/230MM 5,000 Rpm Large Angle Grinder with 4 Hp Motor
I have been using my grinder to cut masonry. It is brand new. However now I can't seem to loosen the outer flange to take the disc off and put in another. I tried using a pipe on the spanner for more leverage but ended up snapping one of the pins off of the spanner. I have another spanner and hope someone has a solution.
What sort of disc do you have on there at the mo? If its just an abrasive disc the easiest way to remove it is to use a hacksaw to cut the disc sideways so that you are actually sawing it out between the lock nut and rear flange. This will release the pressure on the nut. If it is a diamond blade and you have already snapped a pin spanner then I would suggest securing the blade in a vice and using a set of stiltsons/pipe wrench. While in the vice you could also try using a punch in the pin holes to shock it round a bit, then the pin spanner (and leverage if needed).

I had the same problem with 9" Hitachi, worn holes and worn cutting disc.
With a 5" I cut two parallel faces on opposite sides of the nut, just a few mm in and clamped the nut in a vice on these faces, pressed the button and swung the grinder, easy! We use the grinder again.

I agree with the previous solution but would try a couple of drops or Kroil penetrant, K&N knok-r-loose, maybe some heat then try the wrench and the hacksaw last.
