Smooth
Worked great to cut out tile grout for a couple of shower shelves.

Removed thin set from tile grout joints
Bought it to remove excess thin set from some 1/16 and 1/8 porcelain tile grout joints and it worked well for that. Much faster than a utility knife if you have a decent amount to remove. Fit great on my DeWalt 20V oscillating tool.

It works on glass tile
I had to cut glass tile that was put in to close to the outlets on the backsplash and it worked. Very happy with my purchase. Just keep water near to cool off the blade so it doesn’t dull quickly.

The right tool, for the right job
For me, this just became the hands down, perfect blade for cutting through cementitious plaster walls. I have a 1939 built house that I am rewiring, and finally got sick of using a sawzall to open up the walls to run wire. A sawzall ended up doing more damage as I cut through one side of each lath, and then started cutting on the opposite side of each lath, and the vibrations ended up ripping out more plaster than I intended. I burned up 3 bimetal blades on my Multi-tool, and didn't even get one opening cut, before deciding to give this Diamond blade a try. For $10 it was worth a try. I have a really high cement and fine aggregate makeup to my plaster walls with no wire reinforcing, and this blade is perfect for my application. Clean, easy cuts through the plaster, then I have to switch out to the wood blades to get through the lath, but it became an infinitely easier job with better results. I cut (6) 12"x12" openings initially (so 24 lf of cement plaster) and I cannot tell any sign of wear. That alone is worth the $10 per blade.

Wore quick
Worked to cut 2 fan holes through plaster and lath. Pretty well worn out slowing down on second hole. Chinese crap.

Does not cut tile
Do not recommend! This blade is useless. It. hardly even scratched our porcelain tile, much less cut anything. And we have a nice oscillating saw that we used it with. Disappointed.

The first product worth six stars (in my business anyway)
For my specific purpose (grinding concrete), this blade is one of the best low-cost, high-convenience discoveries of my business. The blade is long enough to reach into/under door jambs (even with door hung). Being diamond instead of carbide, it cuts concrete well and for a good while and is aggressive but doesn't gouge the concrete. I have 3 cordless oscillating tools (Milwaukee's blade change process is insanely frustrating-- stay away from that one! DeWalt is a 3-second dream to change blades so I have two of those and love them). Anyway, this blade is where it's at for cleaning up concrete corners and reaching under things (drywall, door jambs, drains, etc.). This blade worked so sell that I was able to effectively buzz across a door threshold and along a short section of wall as if it were a fine cup wheel. The longer-than-normal length of the blade (compared with HD consumer grade) probably helped with its longer throw during oscillations.
