BD 303C 7" X .030" X 1"-5/8" Professional Blade - Okay for tile saw? Too thin? BD 303C 8" x .025" x 5/8" Blade I know this size fits my 7" tile saw but is it going to be too thin for how fast the saw cuts? BD 303C 8" x .032" x 5/8" Blade Same question for this one?
What about this one? 8" MEAN GREEN BLADE
These are off John's website.

I think some of it depends on how patient you are. The thinner blades save material, but if you push too hard they can dish. Also, do you only use the tile saw for trimming slabs or do you cut thicker material like splitting a thunderegg?

I mostly use the tile saw for cutting smaller pieces of rock or rock that I don't want stained by the mineral oil.

but if you are cutting anything thicker than 1/4" I would not go less then .030.

I have to agree with deb193redux. I use a .032 on my 10" that I use for most trim using water as a coolant. I have a .025 blade on my smaller saw and use it just on soft stuff. The blade flexes a lot when starting a cut and cuts really slow. I cut mostly agates.

Donnie, I asked the BD guy while we were at Denver together about using the .030" 7" blade on their MK170 (7" tile saw, 5500 rpm). He thought it would be safe to use. A possible advantage of the green blade would be at high speed there would be no sintered blade rim that could be broken off and launched. Are you sure an 8" blade would fit? What speed is your saw?

If you want a good thick blade, I have a few 8" MK tile blades that cut rock for $30 ea. They must be .050" at least. Made for tile saws but very high quality. A lot of rock clubs have been using them.

Saw speed is 3500 rpm. An 8" definitely fits with a little room to spare. I have been using an 8" blade I got from Lopaki which works great but it's a little scary how it grabs on to the rock & pulls. I find if I don't have a good grip on the rock it will grab it right out of my hand. That's why I was wondering about using the green blade as opposed to the 303c which doesn't seem to be as grabby. I could use the tile blade but some of what I cut is kind of small and/or soft so I don't want to waste anymore than I have to. I did, after all start out with tile blades.

I just looked at that chart. I see the larger the blade, the slower the speed.

At 3500 you would be OK with the 303C. I use the new 301 blades on a 3450 rpm tile saw and they work great. They are .040" though. The 303C has same core and except for the wedges in rim the same rim. I would not use anything smaller than .030" 7" or .032" 8" 303C. The green blades are listed as .031" but not sure if that is core or rim. They are plenty rigid enough as well but don't cut as smooth or fast as the 303C. They may last longer though depending on how heavy handed you are.

I am not as heavy handed as I used to be! Unless I am getting tired & wanting to finish up fast. Soooooooo happy for the 10" lap saw that does the cutting for me but sometimes I need to use the tile saw for other things that require water or are just smaller. Will be keeping my eyes open for a used lap saw 10" or smaller that I can used specifically for that purpose, with water.

Donnie, my first saw was an old Frantom so very similar to your HP. I used oil and stock piled those rocks I needed to cut with water. When the oil got really nasty I would drain and clean and fill with water. Then I would cut the stock piled materials. Then drain, clean, dry and refill with clean oil. It only held a pint so I never bothered filtering. Oil was cheaper then too.
