First and foremost, I would like to extend my gratitude to your representative, [Employee's Name], who provided me with invaluable assistance when I called to inquire about my purchase.

Cuts Like A Hot Knife In Warm Butter This blade was mid priced but had good reviews. I have been using it to install glass backsplash tiles in our kitchen. I have many outlets, and other challenging cuts due to the shape of the tiles. This blade has been knocking it out of the park right out of the package. I am using it on an older Ryobi wetsaw, and my only observation (not a complaint) is that the kerf left by the blade is thinner than the part that holds my safety guard. So, on a really long ...

Fantastic. I’m no tile guy, but this blade is impressive. I was using a Bosch diamond blade that was leaving a serrated edging on the glass tiles. So I bought this blade, I was very skeptical and put it in my cheap 4 inch harbor Freight Tools wet saw and couldn’t be happier. I’m cutting glass tiles with hardly no chipping or rough edges. Takes a few passes and practice swings, no biggie. In this case it’s best to cut the tile face down and free hand the cuts... I was getting corner chipping at t...

These are absolutely the best blades I've ever used. These are absolutely the best blades I've ever used! And I've used a LOT of different blades. Cheap ones, expensive ones, it hasn't mattered.

I'm still on my first blade after roughly 3,000 sq/ft! All porcelain too! The neat thing about these is that about three passes th...

This bit worked very well. I used this bit to grind out old mortar on a chimney needing repointing. I ground most of the mortar with a diamond blade 5" grinder. In the areas like head joints I used this diamond glitter bit pin. It worked very well. It went through the crumbly loose mortar quickly. The hard mortar that needed replacing only because of a crack took longer to grind out. The diamond abrasive held up well. I am done with the grinding and there is still life left in the bit. The long ...

Cut my Bathroom wall tile effortlessly. I used this on a HF grinder to bathroom wall title for a new "electrical switch" box. I marked out the location of the cut with a crayon and used this blade and a water spray bottle. This blade cut the tile like it was butter. Light cuts at a time while water spraying the tile and the blade a bit. Once the tile was out I used this blade again to loosen up the thickset before using a chisel to square everything up. NOTE: The only thing I should have done wh...
