    • Great steel blades
Size: 8" Style: 42 TCG
These blades are the best I’ve used on steel. Thinner blades take less battery, last longer, and cut straighter

    • Worth the purchase!
Put this blade on a old cheap miter saw and it does amazing! Was cutting through 1/4" thick steel without breaking a sweat. Alot better than a cutoff wheel on a grinder. Much faster and cleaner of a cut.

    • Excellent product, excellent service.
This is a legit review, I have not received anything for my review... These Steel Demon Cermet teeth blades are the best blades you will ever use to cut mild, carbon steel. They last longer than tungsten carbide, and I think they are a cleaner cut, that part is subjective, though. It arrived within 3 business days of ordering. I gave it 5 stars in sheerness, thickness and warmth because it looked like it would affect the review negatively if I did not. An 8" steel cutting blade has no sheerness, or warmth qualities and its thickness is standardized. I believe this is the 4th, or 5th Steel Demon blade I've bought from Amazon. Every time they are cheaper than Ebay by $4, or $5. To clarify I am a certified welder fabricator, since 1985, I use these blades professionally. This is not hobby work. I personally use the Skilsaw Outlaw, in my opinion that is the best saw for cutting steel, free hand. Bezos is a bleeding heart pussy, but Amazon is good at what they do. ... show more

    • best blade for the money!
Seems to hold out very good compared to other brands. Blade is missing a tooth and a few teeth have chips and it still cuts good. For the price, I think they are the best blades on the market!

    • Best option for cutting metal
Size: 8" Style: 42 TCG
The best metal cutting blades currently on the market. As long as you use them sensibly, you should get decent life out of each. The learning curve for this type of blade is cutting slow through any given material - if you push the saw to quickly the teeth will shear off. As well, if you do not support the opposite end being cut off; and it pinches the blade - the teeth will shear off. My company runs through at least 50 of these blades a year; so we've tried every option to increase longevity. Until they come up with a blade that's able to overcome these obstacles - this is the best on the market ... show more

    • so much better then a cut off wheel
The Diablo 8" Steel blade slices through metal like butter. Clean, smooth cuts with minimal sparks and no overheating. Perfect for my steel projects—definitely a game-changer for metal cutting!

    • Unbelievable
When I first saw this reviewed on youtube I thought it was a joke. Now that I own one let me tell you it isn't. I installed it in my small Makita 8" chop saw and have now used it only a few times, so I can not speak for longevity, but it works GREAT! I used it to cut 2" pipe and it goes through it almost as fast as my other saw equipped with a Diablo wood blades cuts through a 2x4. It is fast, cuts amazingly clean, leaving a very clean smooth cut with no burrs, and can be handled as soon as it is cut, making almost no heat, except for the sparks. The sparks are hot, gloves would be a good idea as well as long sleeves and eye protection. Can be used in your hand held circular saw and for a little over $30 money well spent even if you only use it a couple times a year. You will not regret getting it! ... show more

    • Good saw blade but needs to be better
Size: 8" Style: 42 TCG
I am cutting 3/16” steel plate 4’x 8’ it cut 8’ good then 4 foot more ok then 4 foot more hard to push it and that was all the cutting it would do and all cuts were done with water cooling on the blade. To cut 3/16” plate it cost $3.00 per foot very expensive
