The QEP Black Widow Diamond Blade is a premier blade for very fast, chip-and wobble-free cutting of porcelain, marble, granite and ceramic tile. The unique diamond-shaped micro segmented laser cutouts around the perimeter keep the blade cooler for superior performance and a longer life. In fact, independent testing has shown that the total average cut speed for the Black Widow blade is 17.14 seconds; faster than other porcelain cutting blades on the market today.

Rated 4.6 out of 5 by 24 reviewers.
Rated 5.0 out of 5.0 by Great blade--reduces chipping Smooth fast cuts, but the real improvement was the reduced chipping. I have typically used the discount tool store diamond blades for my tile saw. I had thought the small amount of chipping was caused by the belt or motor vibration. However, I was rather surprised with how much this Black Widow blade reduced the chipping. For both porcelain and granite the smoother cuts were noticeable. I tried my best to take pictures of this, it's obvious on the porcelain tile, but harder to see on the granite. For only a few dollars more this blade is certainly worth the reduction in aggravating chips. Now I have to buy the 10” version. November 9, 2012
Rated 5.0 out of 5.0 by Great Diamond Blade for Porcelain and Ceramic Tile Need to replace my 7" Diamond Blade for cutting Porcelain and Ceramic Tile. I using it to cut subway tile and the cuts a minimal of chipping. Compare to my other blade the Black Widow cuts were smoother and was were noticeable. I purchase other blade that wobble and this Black Widow was wobble-free when cutting. April 1, 2014
Rated 5.0 out of 5.0 by Cuts tiles like butter Not that I was unhappy with my current Qeb brand cutting blade that came with my 650 XT I bought at Home Depot as it was doing a pretty good job but as soon as I installed and cut the first tile I knew this wet cutting blade was going to be a fantastic addition to my cutting needs. The Black Widow Diamond Blade cuts like butter no chipping, no breakage. Great blade fast cutting and smooth.. August 27, 2014
Rated 5.0 out of 5.0 by Clean Cutting My QEP Premium Diamond Blade for Wet or Dry Cutting (Gold Series) has been out done and replaced. I only had a few cuts at this point, but some thing are as plain as day. I have many other laser/micro designed blades for many saws and you just can't beat them. And QEP Black Widow is just one more of them. One note is this is a WET CUT blade only! May 1, 2014
Rated 5.0 out of 5.0 by Top notch For cutting tile, these blades are the best on the market...They stay sharper longer and will cut through all kinds of tile...These are the only ones I buy when I need wet saw blades! March 5, 2014
Rated 5.0 out of 5.0 by Excellent upgrade for my old tile saw Bought a basic 7" Plasplugs tile saw from Home Depot several years ago and needed to replace the blade before an upcoming tile job in the laundry room. We're setting 18" noce floor tiles that are about 3/8" thick and this saw cuts them a lot easier than the blade that originally came with the saw. I wish I'd upgraded sooner. Blade was easy to fit and I have to apply less feed pressure on the tiles against the blade with this one. Much easier to work with. October 22, 2012
Rated 5.0 out of 5.0 by Excellent replacement blade The blade was very easy to fit and the 3/8" ceramic tiles were just as easy to cut without hardly having to push them through the wet saw. I was using a new wet tile saw with the original blade and that was okay....just okay. But once i fitted the Black Diamond Widow blade, the difference in cutting was very noticeable. It was smoother and there was no sign of any tiny chips at the end of the cut. Guiding the tile through was also easier with angle cuts. I will not bother to use the blade that came with the saw again. A little like trading a scooter for a Harley Davidson November 16, 2012
Rated 5.0 out of 5.0 by A Good Wet Saw Blade! After an initial problem with a faulty saw blade, the nice folks at QEP sent me a replacement blade that works like a charm. The replacement blade works as advertised and sliced porcelain tile with very minimal chipping. I can't yet speak to the longevity of this particular blade, but about fifteen years ago or so, I'd bought a QEP wet saw, and the less expensive blade that came with the saw lasted a very long time before needing replaced. If that experience is anything to go by, then this Black Widow blade should last me a very long time. I wish to commend the QEP Company for their great customer service and genuine concern for the initial problem I had. Their Meagan Gallagher really went above and beyond the call of duty in solving my problem and was a genuine joy to deal with. Thanks QEP, and Home Depot! September 30, 2014
