Norske Tools NCSBP208 5-3/8 inch 50T Metal Cutting Saw Blade For Steel Roofing, Metal Siding, Steel Pipe, Steel Studs & More 2 Bushings ( 5/8 inch To 10mm & 5/8 inch To 1/2 inch)

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!

Bought it 5 months ago and used it to make straight clean cuts on about a thousand feet of 4", 6", and 8" wireway for the aluminum manufacturing plant we've been building. Still works great with only 3 small chips on the teeth.

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.

What an improvement in cutting! I used to cut steel with an angle grinder. This blade on my small battery powered circular saw if far easier, safer, and a lot less messy. Great buy.

Much better than the aluminum oxide cut-off disc's. A really clean cut on aluminum and soft steel tubes.

Don’t last too long

Tried to cut 1/8” angle iron (with cutting fluid) and the blade dulled out within a handful of cuts. Waste of money.

This blade cut 1/4” steel flat bar and 1/8” wall steel tube well. The teeth tips are well set and ground and don’t wear out quickly. I didn’t use it until wear-out so the longevity is based on the sharpness and tip wear after substantial use. The blade runs true, no wobble, cold or hot. . The price was better than competing products. It’s not red, but that makes it easier to pick out.

Used this blade to cut down a 4x8 - 10 gauge steel plate to build a fab table. Burned through a couple of abrasive blades prior to getting this blade. Smooth and easy to control using my Makita circular saw. Beautiful edges.FYI... It threw chips a long way. 15-20 ft so be prepared for some cleanup if you're doing this inside.

Es un buen disco para cortar metal, lo he usado con sierra de inglete, tanto el ruido como la vibración son bastante aceptables, le he usado para cortar perfil tubular de acero y lo ha hecho sin problemas, genera bastante rebaba de metal adherido a la pares del perfil pero nada que no pueda quitarse con una lima.

Excelente serra pra metais, mas o furo é de apenas 16mm(se não me engano) ele não serve pra cortadora de metais da makita, pois a mesma só pega discos com furo de 20mm. Tive que fazer uma "adaptação" usando uma broca escalonada e não foi muito fácil, pois o metal dela é muito duro. Não recomendo a compra pra quem tem makita, pois não sei se é recomendado fazer esse tipo de ajuste, fiz por minha conta e risco.

Worked very well in my small cordless chop saw.

No se desafía rápidamente, he realizado un aproximado de 50 cortés en perfiles de herrería y a aún corta excelente, los cortes quedan perfectos. Considerar usar buenas oregeras para el ruido intenso que genera, y protección para la los ojos así como ropa adecuada por qué naturalmente el corte produce muchas partículas calientes.
