I purchased a used inexpensive 7inch tile saw. I am needing to replace the blade and need some suggestions. I use the saw to cut rocks to see what’s inside and also use it to trim rocks prior to tumbling. I’ve seen many suggestions in the archive but they are mostly blades that are shaping rocks, which I am not interested in. Any suggestions are appreciated and I would like to keep the cost down, if possible.

On my tile saw (12") I used a Hotdog blade I got at Home Depot. It worked decently for a fair amount of granite & quartz but the rim ended up separating from the blade core once it got near the end of life. I'd never seen that happen before!! So if you buy one, watch for that. I also used a generic porcelain tile blade, but I don't remember the brand (it came on my saw). QEP/Workhorse brand are quite decent according to lots of rock hounds but I couldn't find them near me. I would ask Rockoonz for some input, he refurbs a lot of saws and knows his stuff. |

Thank you Mel for the recommendation, but other than the hotdog blade all I can say is what you said, something for granite or porcelain is going to be closest to the same as a lapidary blade, except designed for the higher speed and water lubrication rather than oil. I have had a sintered segment come off of a 303 lapidary blade before so it can happen. Honestly don't know if they're laser welded or brazed on, but the rim and core are pretty dissimilar metals so there will always be a weak point there. |

I've been using DeWalt XP4 blades for awhile. I think they last pretty well...
