IRWINTools IRWIN 7-1/4-Inch Metal Cutting Circular Saw Blade, 68-Tooth (4935560)

This blade is the real deal. I eventually purchased this for cutting ribbed steel panels for the inside walls of a workshop after trying several other lower cost alternatives. I started out using snips and then the abrasive type wheels on a grinder and circular saw. The abrasive wheels worked, but they threw sparks everywhere, were hard to make a straight cut with, and burned the paint on the metal. I decided to give this blade a try after reading many positive reviews from others using it for the same application and all I can say is I should have just bought this in the beginning and saved myself a lot of hassle. It cut the panels incredibly easily and smoothly with surprisingly few sparks. It cuts very quickly and it’s easy to make straight cuts. The only time I had any issues was if the cut was right near the end of the panel, the blade would rip up the thin strip at the end when I started to cut and then it would get stuck on the guard of the circular saw. I only had this issue a couple times though and it was only when there was a very thin piece being cut off. As long as I cut off around an inch or more it was fine. I made 32 cuts on 42” wide panels across the ribs and a couple lengthwise cuts totaling about 30 feet and the blade cut as well on the last cut as it did the first. I did notice a few teeth are chipped, but it still cuts fine. I am really glad I purchased this and I highly recommend it to anyone who’s planning to install metal roofing or siding.

having to cut the gable ends of my out building, this blade made quick work of the project. Worth the money and works very well. Gotta have the right tool for the right job. This is it.

Bought mine to cut steel roofing. Stacked 12 sheets of ribbed 28 ga. by 3' wide steel and cut all 12 sheets in one pass in matter of seconds and NO sparks! Used sabre saws and nibblers in past. No comparison for straight lines and speed. Have also been using it to cut angle iron and bar stock. Many times faster and cleaner than my 14" cutoff saw that uses an abrasive disc. Not having a shower of sparks and the accompanying fire hazard is a huge benefit. After several roofing jobs and many misc. cuts, it is still as sharp as new. If it ever does get dull, any saw shop can sharpen it for around $10 or less. The info says for thin steel but I consistantly cut up to 1" by 6" solid steel flat bar stock with no effort whatsoever. The 48 tooth blade doesn't cut thick steel any faster than this 68 tooth and the 48 tooth will not work as well on thin sheet steel. As a matter of fact, the 48 tooth is dangerous on thin stock as it will over-feed and grab. If you are cutting various different thickness of steel, buy this one, and skip purchasing the 48 tooth. This 68 tooth blade is all you will ever need. For best results give it a shot of WD-40 on both sides of body in between cuts. A little bit of lubrication makes cuts effortless. Yor will find yourself actually holding back on it as it virtually self-feeds into the material. After one job this blade paid for itself many times over. Will never be without one again. Only regret is not buying one years ago.

Have not previously tried one of these blades. It works great, better than expected.

This review covers the Irwin 68t and frued/Diablo 48t blade from home depot.Purchased this Irwin blade for cutting 29 gauge steel metal for a pole barn. Cutting the trim pieces went well, especially where there are bend overs or return bends. Blade was set to maximum depth with out issue.While attempting to cut a stack of 8 corrugated metal panels from the back side didn't go so well. A tooth shank busted off rendering the blade no good. I switched to a frued/Diablo 48t metal blade and flipped the panels over to cut 5 from the front. The frued blade threw sparks and also jumped back when it hit the high ridges having to resort to using a sawzall.Using the sawzall took too long and didn't provide a decent cut. Still using the frued Blade, 3 remaining panels were cut from the back side with the blade set just deep enough to cut through the low ridges. The frued was throwing sparks. This worked well and significantly sped up the cutting process. The high ridges were cut with the sawzall.

Cut through steel cabinet like butter

This blade EATS metal like a hot knife through butter. Had 18 hurricane shutters i had to cut to length. Tried one at a time, then three, the five. It didn't care how many I threw at it, it just chewed through them leaving almost glitter sized pieces. Increadable. Only complait, if that is the deth was just a 1/4 inch shy of going threw the shutter. No big deal as I fabricated a jig for my saw anj ust flipped the pierces, clamped the jig an made the cuts. Cleanup was longer than the cus even though i hung tarps to keep the cuttings from flying all over. Note - wear long sleeves an jeans head covering and a face shield or you will wish you had! I did and was sooooo glad I did so!

This saw blade is the best solution for cutting metal roofing sheets. It does not burn through the metal and damage the paint like other "metal" cutting blades do. This blade literally slowly shreds off the metal creating almost zero heat. I used it to cut the valley roof metal and had absolutely no issues what so ever. After cutting more than 20 pieces of metal and 10 pieces of trim the blade still cut as if it were brand new. It was worth its weight in gold compared to using metal sheers. The only warning i would give is to use long sleeve shirts and dont skip the eye protection with this saw. The metal slivers the saw spits out will get stuck in your skin and bleed. Also, if anyone is helping hold the metal, have them use protective equipment also.
