HARDWIN 7-1/4 Inch 48T Metal Cutting Circular Saw Blade, Cermet Tipped Blade for Steel and Rebar

Works great. WILL NOT FIT the arbor on my evolution saw, but fits ��normal�� circular saws fine. Cuts every thickness steel I have tried cleanly. Had I bought this blade before buying my evolution saw I could have saved a lot of money.

I bought this because I was sick of my wood blades getting wrecked if I hit a nail or anything else. Now I cut galvanized steel, sheet metal, plastic, plywood, abs, lumber, firewood, pallets! Whatever! Its still sharp and cuts smooth after all that random mess! Great value, excellent functionality, excellent durability ! Your biggest drawback is you're going to accidentally cut something because you can't tell its so clean and fast!

Very cool tech. Recommended.

This metal cutting blade looks sharp and well made, and so far it has handled thin gauge sheet metal like corrugated roofing panels without any trouble. It leaves a decent edge and has plenty of carbide-tipped teeth that seem durable enough for repeated use.

The kerf is relatively thin and it worked just fine with my cordless saw. I haven't tested it on heavier materials yet but I imagine it handles a variety of stock just fine.

When I ordered this, it was priced at $23 for a single blade, which is right in line with other metal cutting blades. No complaints so far.

If You haven’t tried these new metal cutting blades, You really need to. I’ve been using standard cut off wheels for. Many years and still do and lots of jobs but These are truly a game changer. The technology has improved so much. These cut accurately, quickly , very low heat compared to cut off wheels, and with less hassle due to Less frequent changing as opposed to cut off wheels. I haven’t physically use this one yet because I’ve got a different size one that I use with great success. Therefore as soon as I saw this one available in this brand, for my other circular saw, I grabbed it. You will not be disappointed gang.

I’ll admit, this blade had me a little freaked out at first. I’ve never used a metal cutting blade that wasn’t made of composite material, so I was skeptical. But I’m thrilled to say that the Hardwin blade is a total game-changer. I tested it first on ½” rebar, then on ¼” flat bar and 1/8” angle iron, and was amazed at how easily it cut through. I wish they made these blades for my chop saw and grinders.
The blade is solidly built, with a 5/8" arbor and a diamond-shaped knockout for worm drive saws. It works perfectly with a standard circular saw. So far, it’s sliced through everything smoothly, with no signs of wear on the carbide teeth, even after multiple cuts. It feels like a durable, high-quality tool in my hands, and I love the clean, precise cuts it leaves behind—no chips or rough edges. This has quickly become my go-to blade for metal cutting, and I’ll definitely be picking up another one for future projects. It’s an investment worth making, especially if you regularly work with metal like I do. I’m curious to see how long it lasts, but it’s already far exceeded my expectations.

Excellent metal cutting blade.

I use this blade in my cordless chopsaw to cut thick aluminum square tracks with spring steel in side. It cuts smooth with no issues. I have cut some steel 2x2 L brackets as well. Very smooth cut and very happy with the price.

7-1/4 Inch Metal Cutting Saw Blade - 48T Cermet Carbide Tipped for Rebar, Angle Iron, Pipes, Channels - 5/8" Arbor, Low-Heat Spark-Free Thin Kerf Design - Replacement for Diablo D0748CF

This is an excellent blade. I put it on my old Skil saw, and have been using it to do a lot of precise cuts on a wide variety (shapes and sizes) of steel tubing. It's made a lot of cuts so far, and it's still going strong. I've had far more expensive blades burn out faster, so I am very impressed. At $20 each, they are priced very reasonably.

Very smooth cuts with my cutoff saw. Very happy with the results.

I know this blade is designed for a chop saw but I don’t have a chop saw. I DO have circular saw that accepts these blades and ⅝” arbor. I also have a need to cut aluminum for my DIY projects. So onto Amazon for a searching mission and I found this. It was at the right price, perfect! I have only cut one thing so far, my mountain bike fork tube, but this worked very well, VERY well. I mounted my forks in a vise, then got my saw ready, mark ready, some lube, and like butter, this blade cut through that tube, cleanly. It was fantastic.

To drive home the idea that this is "indeed" a replacement blade for a Diablo blade, the blade that I received was even labeled "Metal Devil", not "Metal Fiend" as shown on product photos. I don't care much for the name (hence I never purchase "Diablo" blades or watch the New Jersey Devils hockey team), so I probably would not have ordered this blade either...

Well getting back to business - this blade cuts metal very well - in my case, it cut a 3/4 inch stainless steel rod like cold knife through hot butter.

How long will it last? We'll see.

Since few of my cuts with my 7 1/4 inch saw are metal, I just need one dependable blade and this fits the bill. I tested the blade cutting an old TV wall mount that is hard and rigid, and didn't have any problems. It cut smoothly and cleanly, without any chips on the front or back. I carefully looked at each tooth after a couple of cuts to see if there was any damage and didn't see any. So, this just became my only blade to cut metal for my 7 1/4 inch saw.

This thing is awesome. I've tried other metal cutting blades, and they wore out so quick that I couldn't justify their higher cost, and didn't really cut all that well to begin with.

The blade is manufactured with both standard 5/8 arbor, and the diamond-shaped worm drive saw knockout in the center. The blade says it is rated for a maximum of 5500 RPM. For my testing (just to see if it would survive), I mounted it on a standard circular saw, rated at 5400 RPM, and it worked great, but I suspect that the blade will last longer if mounted on my worm drive saw, which only turns 4400 RPM. Since it works so well, I will be switching it over to that saw just to keep it going as long as possible.

Last month, I built a tube bumper for a 4Runner and chicken tractor to expand our egg layer flock. For both these projects, I used galvanized 1 1/2" schedule 40 pipe that I had laying around, and I got thoroughly sick of cutting this stuff on my old abrasive-blade chop saw. In fact, I did most of the chicken tractor with a grinder and cutoff discs, just because they were actually faster.

I WISH I had this blade when I was doing those projects, because when I tested it out, I used a piece of that same 1 1/2" pipe. This Hardwin blade zipped through a piece of this pipe in roughly 2 seconds, and it would take close to a minute with a grinder or even longer with the chop saw. Better yet, the carbide teeth looked just as good when I finished as they did when I started, so I believe I could get through a lot of careful cuts with this blade.

Also, this works better for odd angles or notch cuts, because it's just in the same old circular saws I'm used to using in the construction business. Being able to move your saw to the workpiece is just handy sometimes.

Anyway, I can't recommend this blade enough, and I would definitely order another the next time a big metalworking project comes my way.

I didn’t have a direct application for this sawblade, so I just did a few test cuts when it arrived. I have a few 8 inch I-beams lying around the property and decided to see how this thing goes through the top of the “I”. With the saw, it cut through the thin edge of the I-beam, with no problem and kept its momentum through into the thicker part. I didn’t cut through the whole top of the I-beam because the blade was heating up so much. Overall, it seems like a nice blade that will work very well for less extreme applications than what I put it through.

While I have a metal chop saw, it is nice to be able to pop this blade on my Porter-Cable circular saw while I’m on a jobsite instead of lugging the chop around. The ceramic coating on the teeth is substantial and I fully expect long life out of it.

I tested this on some 2” x 4” aluminum extrusions I am using for a little project in my garden, and it cut cleanly and easily. The blade seems well balanced, and I didn’t get any vibrations.

Nice blades
