Beast Pro Porcelain Standard Core Tile Saw Blade - 7" Wet Ceramic Tile Cutting Tool with Thin Kerf Core & 5/8" Arbor - BPS7

Works well to start, but a dozen cuts later in porcelain tile, it starts to labor. Really slows or chips start from the oscillation of the blade. Top down cuts are better with the reinforced alternative, but this is better if you have to notch or shave. Non reinforced blade can wander up to 3/32 in 12 inches.

This came quickly. Stays sharp to make clean cuts

I didn't like that they have splits in them.

I am a professional tile installer. Blades Off the Shelf at Menards or Home Depot are just as good or better.

this is the best blade for porcelain I have ever bought straight cuts

Lasts a while. Doesn't leave chipped edges.

My guess is I must have received a defective blade. Rough cuts and broken tiles. Never performed even on ceramic tiles no matter how slowly fed. Don't waste your money, blades at less than half the price will perform better.
