broseph82 I'm not really sure what happened. I was cutting some slabs, Unakite and Rio's, it wasn't until I was cleaning up that I saw the blade was broken. The Unakite was easy to cut and the Rio's weren't too bad. I was holding them but using the tile guide and my vise as support. Andrea

Hand feeding things into a blade makes it real easy to toast a blade. I lost a 18" blade this spring, when the gorilla glue failed. It stinks when it happens, but eventually it does to all of us. Hopefully that wasn't an expensive blade. Robert

My first instinct is along the lines of Catmandewe. I don't see any dishing or warping of the blade around that point, and there is a suspicious amount of corrosion at the break point. looks like a dud blade to me.

I covered up the saw with a plastic bbq cover because we have been getting a lot of rain and the saw is at the edge of the patio. Could that have caused the corrosion on the blade? Andrea

What type of blade is this? please dont say covington gold It was the blade that came with the mk 101. It is for porcelain. It has slits around it, I think to help with cooling. I'm just glad I did accidentally touch it while cutting. That wouldn't have been good. Andrea

So you are cutting Rios with a blade meant for porcelain? I'm thinking that is equivalent to trying to whittle with a butter knife. Sorry the blade broke, but you need to pony up and buy a good quality lapidary blade.
But, I bet you have figured that one out already. Glad you weren't hurt. That missing piece had to go somewhere!

I would like to buy a lapidary blade that can be used with water. I would order it today if I knew exactly which one to get. I know I've asked before about this but I can't remember what was recommended. I'll have to go back and look. This was the blade came with the saw and stated it was good for porcelain,stone, granite maybe marble. I can't remember exactly how it was worded, but I thought it would be ok... Obviously not.

I just looked up the MOHs hardness for porcelain and it said 6-7 and agate is 7. I know I looked this up before and that is why I thought it would be ok to use a blade that was good for porcelain.

I'll take you word for it that porcelain is a 6-7, never considered it's hardness. But, I can cut a porcelain tile with a screwdriver, and tile is probably what your saw was intended to cut.
Porcelain tile (most tile) is basically a kiln fired, or pressed, piece of clay or dust made out of pulverized rock. The "porcelain" is a thin glaze coating on top of the base material.
I'm not saying that a tile saw can't cut some types of rock, many here only use tile saws. Just that the tile saw has it's limits.
What sized blade are you needing for your saw? I'm sure folks here won't mind throwing out some suggestions for a proper lapidary blade.

captbob I need a 10" blade. I was just looking at the MK 303 on the MK website. It is a lapidary blade that says to use a water soluble coolant, but I don't know if that means I can use plain water. I never thought about porcelain being just a thin layer on the tile. Andrea

Hmmmm...not sure that's going to work. I can go through 5 gallons of water in 15 minutes or longer if I put the pump in the dirty water.

Sorry the blade broke, but you need to pony up and buy a good quality lapidary blade. But, I bet you have figured that one out already. Glad you weren't hurt. That missing piece had to go somewhere! Capt, I cut Rio Grande agates all day long, day after day, with a porcelain blade (MK 225). It has been in service for nigh onto 3 years and still going strong. Porcelain tile is tough stuff, and a good porcelain blade should stand up to lapidary uses. I'd go for judging the culprit as a bad blade. Its hard to imagine someone twisting the stone enough to break outa chunk like that so its probably materials defect. Tom As to whether porcelain tile is just a thin hard layer on a crumby base, . . . maybe my wife only knows how to buy the expensive stuff, but a bathroom remodel a few years back required my contractor to buy a special blade for his tile saw, the regular tile blade wouldn't cut it. Just saying.
