Before finding the Helix Copperhead blade, I used Dewalt XP4 and MK Diamond MK-415 blades. Both of these blades generally have good reviews, but they cannot touch the Helix Copperhead for smoothness of cut, lack of chipping, and lack of breakout at the end of the cut. I use the Helix blade primarily on porcelain tile and the cuts look factory on rectified tile. My machine is a MK Diamond 10" wet saw with a belt-driven blade arbor. The only non-positive comment I will make concerns the thinness of the blade. It has a thickened center section, which helps the blade run true. However, because of the blade rim thinness, it is possible for the blade to deflect slightly if pushing the tile too fast - an effect that is easily remedied by slowing cutting speed.
