I am sure I asked this before, but couldn't track back the answer.
While I would like to buy a lap saw, I will have to stick with the tile saw for now. The saw it comes with is thick and I was surprised how much material it ate.
I have seen thinner tile saw blades, but I am concerned about safety. What direction should I look to?

Here's the 7" blade I purchased for my tile saw. It's thinner & seems to work OK ( and is cheap enough).
180mm 7" Super thin saw blade

It's a lap disc, would that be safe on a tile saw?

If you are wanting to use it as a flat lap to grind with, there should be a thicker master lap behind the lap to keep it rigid, so there would have to be enough threads on the arbor to fit all that, as well as modifying the slot in the saw top. The wider slot will cause problems when using it as a saw. Laps are capable of the high speeds of a lap disc, but centrifugal force will sling almost all the water off, so dust and short lap life will be an issue.

It's a lap disc, would that be safe on a tile saw? NO, it's a saw blade, with only diamond around the rim, NOT a flat lap. It's a 7" sintered diamond saw blade from Hong Kong, no less.
They describe it as "segmented" but it's NOT, it's a continuous rim diamond SAW BLADE Works fine on my 7" cheap tile saw  Patty

liveoak never tried a blade from lau*** but been buying carving burrs and core drills from THK for years, I gather you like the blades?

It's been holding up pretty good Lee, Rockoonz - even cut some thin intarsia strips pretty nicely. So it cuts smoothly enough. Patty |

Next year I will be buying more geodes and my concern was thinner blades meeting more solid geodes and it being safe

wargrafix there may be a small risk to the operator when hand cutting on a tile saw, but if the rock isn't lifted off the table and especially if you pull it through from the back of the saw it's pretty small, a lot less than most power tools. Risk to thin blades getting bent is a whole nother issue, especially with a round rock that can accidentally turned and bind up and bend the blade.

Thank you for your response. Everyone has been amazing. I watched a fair amount of videos and realized that from the back is far safer and smarter. I took the appropriate protections, gloves and pace protection. Cutting on the saw was actually really good and having used power tools in the past, its pretty easy.
I was not prepared how much material the saw blade ate. How thin a tile blade can go without being a problem for a solid geode?

How wide is this compared to the default sold by skil or similar blades? |

The blade on e-bay is
Thickness : 1.3mm
It's much thinner than what the tile saw came with.
Not sure the specs on other blades.
I'm sure you can easily look up the specs on any blade.

A 1.3mm rim on a seven-inch blade might be considered thin in the tile business but it certainly isn’t in our neck o’ the woods.
I run the same size (0.050 of the King’s inch*) on a 14” saw w/no problems.
* derived from the Latin uncia, one-twelfth of the Roman foot. Once defined as three grains of barley, dry and round, placed end to end, lengthwise, it’s now derived from the distance light travels in a vacuum in a period of time based on the frequency of a Caesium-133 atom.

While I know I still have time before I buy next set of agates and geodes, Is there one on amazon that I can order?

A bump.
What's a recommended thin 7" tile saw for cutting geodes?
Amazon links preferred

Those are great recommendations. If I want to go continuous blade?
So. Many. Choice

Lapidary is not a cheap hobby. In the long run it is wise to invest in better equipment. When I bought my Genie there was a deal for the trim saw attachment for almost free. The saw uses an 8 inch .032 MK303 blade. For trimming it is fine but when I used it for slabbing it ate blades. I bought a 10 inch slab saw the has about the same kerf, vise, power feed and cuts with oil. A blade lasts much longer.

I am more interested in cutting geodes and agates. A lap saw is a bit pricey for me. Right now I am sticking with a tike saw. The thin blade is what I am looking at.
The supplied blade eats material
