I would not advise using a diamond blade to cut asphalt. It will most likely just melt on the blade. If I wanted to cut it? I would probably buy a cheap carbide wood blade and just cut shallow passes. Using plenty of protection from the flying debris. A second helper holding a good shop vac would be good or a deflecter of some kind. Try nailing down a straight edge to the discarded side too for a crisp edge. Spraying some WD 40 on the bade now and then should also help. I've never done this. I'm just going from past experiences. I hope this helps. Remember safety is key. Eye and hearing protection. In this case a ventilater too. There is no sense in saving a hudred dollars only to be hospitalized. Let someone else do it, if you can't do it safely.
Yes. It cut through 4X8 concrete pavers. I am sure it would have no problem with backer board. Lots of dust though.
I used it to cut real rock from Arkansas and it really sent the dust flying-would not recommend using it without wearing a mask. Excellent item to use.
Yes but would not recommend for the average person also check the maximum rpm of your grinder. It would need to be under 8730
You could find a thin washer that will fit on your arbor. Place that on after you place your blade on. Then secure it. Before running it check to make sure it is placed properly and never change the blade with the power cord plugged in. BTW: It sounds like you might of lost the pressure washer on a circular saw. You didn't post what kind of tool you are working with.
Marble is soft so the blade, if held in the hand would be all over the place. Not recommended.
You need a smooth diamond blade for tile or else it can chip, a segmented blade is good for concrete because you can cut faster and looks don't count as much . Near as I can tell this blade is segmented.
I made a few cuts of 1” granite with no problems. Don’t know how it will last on big jobs
If you are meaning the arbor reducer ring, it is a press in fit. I have them pop out all the time when changing to different blades, and merely press back in place by hand. If by chance the ring has rounded, I would think it could be replaced with a similar reducer from another blade. I always save them when I discard a blade. Hope this helps
