Good Afternoon,

I have cut retaining wall blocks with my worm drive and a dry diamond blade. I think I payed more like $30.00 for it but it has lasted through residing a house in concrete plank (you have got to love LP siding, good for mushrooms) and my brother in laws wall. Use a good respirator, not a dust mask, tight sealing goggles and ear plugs. It is messy.


PS works on carbon fiber composites, very nasty.
