Norske Tools NCSBP216 10 inch 72T Metal Cutting Saw Blade For Steel Roofing, Metal Siding, Steel Pipe, Steel Studs & More 5/8 inch Bore

I was concerned about the longevity of this blade specifically because of one of the negative reviews I read stating that you only will get 1 good cut. Fortunately, I read many more that said it is a great blade and so I took a chance. The price is incredibly reasonable for a 10" steel cutting blade and I have used it to cut ceramic stone coated steel shingles for a 2,800 sf roof. My biggest fear was that the teeth might grab on the shingles and cause a disaster while cutting - unfounded fear, not even close to happening. My biggest concern was that the ceramic stone coating on the shingles would wear and dull the blade in short order - unfounded concern, it's as if the coating doesn't even exist (though I will say that I only cut the shingles upside down to lessen the blade's exposure to the stone coating). That blade cut through EVERY shingle I had to cut like butter (overused term, but it's true) and there were a lot of them. It's a mixed hip & gable roof with lots of 45 degree cuts for the hips and valleys. The blade is as sharp now as it was when I started the job. Since it cuts so easily and quickly, there is very little heat buildup like there is when using an abrasive cutoff wheel. I just used it on an inexpensive 10" sliding miter saw (nothing special) and it did the job with flying colors. Would definitely buy it again and in fact, I am going to buy a backup soon just for the heck of it. It's that good, and it's that inexpensive!

I have a table saw that I cut 1/4 inch plexiglass on and also aluminum. Over the years I have used normal carbide wood blades which do a so so job. Otherwise I prefer Diablo blades. This blade says it will cut steel, but I will never know.This blade has a very thin kerf. Upon installing it, I needed to cut some 1/4 inch aluminum. This blade went thru it as easily as it would have cold butter. I'm very impressed.

I built a 10x16 shelter for my Shetland sheep with the roof and upper half of the walls being good quality sheet metal. After using a cutting wheel on my grinder to cut the metal for my pole barn, I investigated alternate options which lead me to this saw blade. Brand new it worked amazing, going through the steel like butter. After about 15 panels it became much more difficult to get across the panels. For thinner metal it would certainly last longer but I'm very happy with the cut quality and ease of using a circular saw versus a grinder.

I had some corrugated steel roofing to cut. I tried a circ saw blade turned backwards and an angle grinder. The saw blade was loud as h e double LL but did a fair job. The angle grinder was almost impossible to control. I got this blade and it goes through the roofing smooth as glass and not nearly as loud. I also tried a jig saw with a metal cutting blade which did a good job. I had put ear plugs in my ears by this time so I really don't know how loud it was. WEAR safety glasses. Wear two pair if you have them and can put them on. The metal shavings fly everywhere. I assume so does sawdust but being so light in weight it, you don't feel it. The shavings are also hot.

I had 24, 1" diameter mild steel tubes to cut one at a time with minutes in between each. It got through 4 like butter, another with a bit of difficulty, and was dead on the sixth. Didn't push the feed rate. Didn't burn the blade. Pretty sure it wouldn't cut butter now. Back to the Sawzall. It's a pain, but gets the job done.

I needed a way to cut metal roofing panels, so I tried this. It made very clean cuts without leaving an extremely sharp edge, and I was able to cut the roofing accurately and with minimal fuss. It was also a lot less money than they wanted in the local home improvement center. Just be sure to wear eye and ear protection - the process of cutting metal throws a ton of sharp metal shards in every direction, and it is rather noisy.

Made about 15 cuts in 14ga. Slotted angle. Cut through it like butter. No significant decrease in blade performance noted after 15 cuts. Minimal sparks. Very clean cuts. SOOOOOO much better than abrasive wheels. Love it!
