Going thru too many blades on the HF tile saw. Any recommendations for a 7" blade that will last? Continuous, segmented or turbo rim?
Thanks

MK225 Hot Dog also marketed by Barranca as the Agate Kutter. It is a tile blade but as said "porcelain blade" so has a different matrix and very high diamond content so cuts hard rock well. You can also use the MK/BD 303C blades which are available in .030" and .050". Standard tile blades have a very hard matrix so cut hard rock slowly and poorly but make excellent grinding wheels. Even in tile blades you can find a difference. MK tile blades cut tiles generally chip free while Home Depot Chinese blades chip like crazy.

If I were to get an MK225 for my lapidary trim saw what RPM should I set it up to run to get the most out of it. Chuck |

Those hot dog blades are worth there weight in gold. I have used about fifteen of them. When there cashed from a tile project they go to the lapidary saw and will work until I completely wear off the diamonds.

Just remember its s slotted blade (like many tile blades) and may be more of a finger grabber than a totally continuous blade. The slotted design might also not be the best for precise cuts of soft material. I've literally cut thousands of slabs with a 12" blade I bought for my slab saw. The slots may also warrant an adjustment in oil/coolant levels if they carry more to the work surface.

The Hot Dog is slotted but the slots are pretty thin . I have been using one for awhile and not had any finger cutting issues . Not saying it couldn't happen but I think you would have to be more clumsy than me to cut your finger .

Just to add a little more info on hot dog blades. Each one I use in a residential,commercial application. typically porcelain tile but granite marble or ceremic tile application. These blades only wear out at about the point I set over ten thousand square feet. That doesn't mean ten thousand cuts but a lot of cuts. When they are no longer are adequate for the job saw I use them at home cutting rocks and corners off of performs. When I said I wear the matrix of diamonds down to the sintered core I mean to the steel part of the blade. Unlike a continuous rim blade they can burn you if you put to much finger pressure on the bottom 3/4 inch of the blade. And they will take your fingernail away very rapidly as any diamond blade would. This is over 20 years of personal tile experience. Best advice on using them for rocks is don't go to fast. Take your time. Un like a lapidary saw that takes ten minutes you can make a cut in a couple of minutes. The slower you go the better the cut and less heat and the blade will cut for a long time.
