STM040A10HP 4" Granite & Marble Segmented Turbo Teeth Diamond Blade for Cutting Granite, Marble, Stone, Pavers, Concrete, Brick, Block, Stone, Tile and Masonry Materials.

I used this with a Dewalt 20v Cordless circular saw to cut 1.5" thick granite steps and 1.25" thick granite slaps for front door steps and landing. I'm a DIY homeowner and a couple of pros were skeptical that a cordless saw with this blade could get the job done. I've cut about 20 feet with this blade and its still not worn out, but I think its close to worn out now. I used a garden hose directly on the cut to keep blade cool and eliminate dust. It worked very slowly (about 10 inches per minute). The cut it surprisingly clean. I thought all that water splashing around might kill the $89 cordless Dewalt saw but its seemingly fine. I would not try this with a corded circular due to electrocution hazard or alternately the HUGE dust cloud if cutting dry.

Cut many pavers. Blade worked very well on a wet saw

This blade works really well and i am pleased with how easily it cuts. I have cut a lot of block with it using a dry saw, and it still works like day one. Remember to let the blade do the work, and it will last a long time at a great price.

Not the best concrete blade

Concord Blades STM070D10HP 7 Inch Granite & Marble Segmented Turbo Teeth Diamond Blade This item was delivered on time, performed as stated and for a reasonable price; I used it to cut, several, replacement fire place refractory panels (which were much harder and denser that the originals), after trying a standard masonry blade, which balked, the Concord blade was still going strong, when the job was done.

Purchased this hoping I could use it on table saw as opposed to using actual tile saw. It is a dry cut and as I found out it is for rough cutting as it will create chips along edge. It also appeared un-ballanced and vibrated a lot more as compared to wet tile saw. I will be returning.....I ended up purchasing a wet tile blade and kept it wet with garden hose which worked for the limited work I needed to do.

Worked very good

I purchased these for one of our men at work along with another brand blade that costs twice as much on here. When he came back and told me to order the good blades again, I immediately re-ordered the more expensive ones. Whoops... he meant these! Of the two brands I ordered, these are still holding up whereas the other is completely done. I've never had a more positive review from our guys about a blade before and figured other people might benefit from it as well.
