I mounted this on an old chop saw (miter saw), and it works wonders for cutting through metal. I've used it to cut through mild and stainless steel, up to 1/4 inch thick, and 6061 aluminum. I was surprised at how easily. Cutting through that 1/4 inch steel felt about the same as cutting through a pine 2x4. Quick and easy, with very little downward pressure on the handle during the cut. And the cuts are clean and smooth.My chop saw spins at 5000 RPM, and this diablo blade is rated at 5800, so it has been a good combination with no problems. Exceeding the max of 5800 may very well cause problems such as dulling the blade, so keep that in mind if your saw spins faster, and many do.While researching this blade, one reviewer commented that it is good for cutting through metal when the entire blade width is in contact with material. However, it is not good for shaving material off the end of a piece, as is commonly done to make a piece of wood just a little shorter. I can confirm that it's not good for this when cutting steel, as it creates a lot of vibration, and I was concerned that even a tightly retained piece could be sent flying. But for cuts down the middle of a metal piece, it's great.Since I'm too lazy to switch it out for a wood blade to make the occasional wood cut. I can confirm that it's a perfectly adequate wood saw. Not the best for making furniture grade cuts, but just take your time going through wood, and you get a clean enough edge for your rough cuts.

This blade was well worth it. I bought this for my mom’s bf who was helping me cut hurricane shutters to fit my windows. This blade didn’t spit crazy sparks or sound crazy . We got it in October and we have used it a bunch on other projects and the blade is still sharp and cuts smooth.

Handles bar stock, sheet steel, aluminum, etc. Get one. Works fine on a table saw, better if you drop the rpm. Must have for sheet metal cutting in the small shop. And much to my amazement it lasts. First one survived almost a year in my shop. I'd have been happy if it lasted a couple months. I was expecting maybe 1000 - 2000 inches of cut in 1/16 " steel. Got at least 10x that much, including heavy steel plate 1/4 and bigger. Final observation: when it dies, it dies fast. Cut pressure way up, speed way down.If you do sheet metal buy a couple. Get rid of the angle grinder.

Bought this to cut heavy duty galvanized steel roofing panels. Builder has riveted and glued sections together so I had one giant 16x16’ square to cut up into pickup bed sized pieces. I started trying to cut it up with and angle grinders and quickly decided that was going to be to costly and time consuming. The double thickness pieces ate blades at a prodigious rate.This blade was the trick and then some. Honestly it felt too dang easy. 16 foot cut through double thickness metal roofing in lass than a minute. Since it was already on the saw it got put to use for some general demo work after. It cuts wood as clean as a finish blade but almost as fast as a ripping blade. One of the best saw blades I’ve ever used.I can’t speak on longevity yet but it’s amazing that it’s still as sharp as it is after a dozen metal cuts. Price is steep, but I would probably pay it again.

Cutting aluminum and stainless steel sheet with a circular saw may seem crazy but it works great. I have had the aluminum specific blade for a couple years and it is awesome for ripping aluminum sheet for boat projects. The Stainless Steel blade works "good" but not great. I noticed a big negative change in cutting performance over a relatively short period of time (only a few cuts) which means that cutting stainless material with a circular saw is going to get fairly expensive using this method. It still beats using a band saw as the cut can be made VERY straight on large pieces of material. It's a "good" blade but I don't think it's great for the $$ paid.

I like fabricating random stuff out of metal, and bought this because I was sick of the messy cuts abrasive saws and grinders make. I didn't expect much, but this blade is great. It cuts through 1/8" steel cleanly and doesn't wander the way abrasive wheels do. It saves a lot of time cleaning up and grinding the cuts before welding. I can't speak to how long it will last, but the amount of time it saved me building a picnic table frame was worth the purchase price alone.

Great toolBought a few now and they cut 1/4 plate
