Questions & Answers

Can I wet grind concrete with the Rigid diamond cup wheel?

I need to grind down a hump in my concrete floor and want to minimize dust.
Asked by: MT
Works great with water. I suggest working small areas and stand a few 2x6 blocks around the area you are working to contain the wet muddy spray. This worked great for me and made cleanup a lot easier

Can I use a 4" grinding wheel on a grinder designed for 4.5" wheels?

Asked by: BobM
yes. buy a 4-5" shroud, the 4-5" wheel is fine in the shroud and with the right angle grinder. there are at times fitment problems between the 4 items (see vacuum below): so plan ahead you may have to switch things around despite your planning. ALWAYS USE DUST CONTROL: a grinder dust shroud connected to a shop vac with a proper filter and likely wear a safety mast rated for silicon dust as well. i was told by a 3M agent their economical 2091 is ok for intermittent use: but they have special ones for professionals who continually work in fine silica dust areas. in general: a larger wheel (ie, 7") would take more power than your grinder has for more than intermittent use, it would over-heat.

Is this a good item to help remove thin set from a patio after removing ceramic tiles?

Is this a good item to help remove thin set from a patio after removing ceramic tiles?
Asked by: MB
Yes. try and keep wheel flat. Wheel does a good job of creating a flat surface, the double row of abrasives make it harder to gouge surface because you have to put alot more down pressure on the wheel when your flat.

I just threaded this onto the shaft on my angle grinder, no lock nut. Worked flawlessly.
