I am a DYI'r, I am looking for a saw blade to cut Marble, Granet, and Travertine that will not chip the edges of the cut. I am looking at the Target Superlox GM blade which claims to cut chip free. I have a 7" tub saw. The blade is expensive $140 but I would be fine with that if it works as advertised. Any experience with the product?? Any other suggestions??? Also while rooting through the Target catalog I found a product called Dri Bit for cutting round holes in ceramic and stone in 1", 1 3/8", 1 5/8", and 2", I thought it might be useful in the shower; again the same questions. Great forum, thanks for the opportunity.

I'll just comment on making holes in tile. You don't need any fancy core bits, unless you need perfect cuts, which is few and far between. A good grinder with a good wheel will give you the same reults.
