HARDWIN 6-1/2 Inch 48T Metal Cutting Saw Blade, Cermet Carbide Tipped Blade for Steel, Angle Iron and Threaded Rod

Wow, this cold-cut blade exceeded all expectations. I wanted to test the hype, so I grabbed my old 4500 RPM circular saw and went to town on a rusty, 20-year-old stainless steel awning.
The results? Insane. It cut through the thick tubes smoothly and quickly (refer to pics 1-4). I was worried about wear, but after inspecting the edge, it’s practically untouched. Only minor sticking, which is normal.
The build quality is top-notch, and the packaging was secure. The only key is RPM matching—don’t run it too fast or it’ll hurt the blade. When matched correctly, it’s durable and efficient. Oh, and the support team was great too. Total recommended! ⭐⭐⭐⭐⭐

Produces significantly cooler cuts with low heat buildup and minimal sparks compared to abrasive blades, allowing for safer and quicker handling of cut pieces. Does still make some dust, but not nearly as much as other blades.

Delivers clean, smooth edges on mild steel, angle iron, and threaded rod with reduced burrs and material waste thanks to the thin kerf design. Does an excellent job on roofing panels and thin sheet metal.

Teeth are somewhat fragile. Requires careful, light feed pressure to avoid damaging the teeth. Aggressive pushing will shorten blade life.

Primarily optimized for mild steel, may underperform on harder alloys, stainless steel, or very thick stock.

Reasonable value for the money for home use or light commercial work.

I ordered this for my circular saw since I have had to cut some aluminum track and some sheet metal for different projects and it is a winner. As you can see in the picture it has a thin kerf so the cuts are clean and don't leave burrs or rough edges. Installation was just as easy as switching out any blade on my circular saw. For the price you can't beat this deal at a box store. An all around good, clean-cutting metal saw blade for general use. I would definitely recommend this cost-effective saw blade for your metal cutting projects.

This 6-1/2” Metal Cutting Saw Blade fit perfectly on my Dewalt 20V MAX 6-1/2” Circular Saw. This blade works well on my saw for cutting thinner metal and with a powerful brushless saw it would have the ability to cut the thicker metal and to cut faster without being slowed down. This Saw Blade would also do very well with a corded Circular Saw as well since it would have more power being plugged in and using 120VAC. Overall this is a great Saw Blade for many small jobs around the garage or shop.

This is my first circular saw METAL cutting blade, until now I had only used reciprocating metal blades. Huge difference! Goes through angle iron like butter, as they say, where the recip saw takes its good time.

The Hardwin blade arrived quickly, and fits my compact circular saw very well. It runs true without vibrations, and not only is sharp, but looks cool too!

I cut a few metal pieces and indeed, not much sparking at all. Seems to stay cool too. Compared to an angle grinder with cut-off wheel it's like night & day.

Won't hesitate to get a spare once this one starts to show signs of age.

This Hardwin metal cutting saw blade is impressive. I normally use a grinder to cut metal, but I decided to give this blade a try, and I’m glad I did. I used it to cut some pipe and the results were outstanding, it sliced through easily and the cut was clean. The teeth are extremely sharp and cut through the metal in no time. I haven’t tested it on heavier materials yet, but I’m confident it will handle them just fine.

This saw blade feels heavy and well made the moment you take it out of the package. It runs smooth and produces noticeably fewer sparks and less heat than other blades I’ve used. The cuts are clean and even, and it holds its edge well through several pieces of steel and angle iron. The thin kerf helps it move quickly without bogging down the saw.

The construction feels like a higher-end industrial blade rather than a budget option. It tracks true, doesn’t chatter, and leaves a clean finish that requires almost no grinding afterward. It’s a solid upgrade if you cut metal regularly and want both speed and precision in one tool.

We put this blade in an older Ryobi cordless saw that wasn't getting used much and dedicated it to metal roofing cutting duty. Having a dedicated saw is nice and saves wear-and-tear on the blade in our DeWalt saw when _someone_ accidently forgot to change blades. This blade is a perfect fit. It comes packaged well to protect the teeth, and the teeth are sharp. It makes nice clean cuts on a single thickness of metal. After half a dozen cuts there doesn't seem to be any change in sharpness. The blade has a thin kerf and there isn't as much dust/shavings as we were getting with our other saw. This is a relatively inexpensive blade compared to others, and is doing a great job for us.

I have been using this blade on my cordless skill saw. It cuts nice and I think it will last fairly long. I have not cut anything real thick with it yet but it does cut thinner sheet metal with no issues. The only reason I give 4 stars may have more to do with my saw and not so much with the blade itself so I would probably prefer to give 4.5 stars. It leaves a pretty rough cut with the cordless. Maybe the speed is just a little too slow or too fast, I'm not sure. Regardless it is much faster then using a cut off wheel on a grinder and doesn't shoot sparks all over which is a big benefit. I think the price is fair assuming it lasts long. IF it doesn't I will revise this review, but I have no reason to believe it won't last long. I have a name brand blade on my corded worm drive saw that cuts a bit cleaner but it is NOT as handy as the cordless. So this blade is very handy and seems to be a good quality blade. I would most likely buy another one at full list price if I need to even though I got this one at a big discount.

I put this blade on a compact 6-1/2" saw to trim angle iron, conduit, and a few steel brackets, and it chews through them much faster than a recip saw or cut-off wheels. The cuts stay surprisingly cool with very little sparking, and the edges are clean enough that I only need a quick touch with a file instead of a long grinding session. It also tracks straight without grabbing or wandering, which makes it easier to follow a line on thinner stock.

The blade feels solid and runs true, with a thin kerf that keeps the load reasonable on a cordless saw. As long as I keep the RPM within spec and feed it steadily, it doesn’t chatter and the cermet teeth stay intact. You still have to respect it: pushing too hard or trying it on the wrong material is an easy way to chip teeth, and I would keep it to mild and structural steels rather than hardened or mystery alloys. The packaging isn’t very specific about every metal it’s suited for, so I rely on the product description and a bit of caution there.

After several cuts in angle iron and rod it’s still sharp and the black coating hasn’t gummed up, so early signs on durability are good, but I haven’t yet logged the kind of hours a full-time metal shop would. For occasional fabrication and cleaner cuts than a grinder, though, it’s been a very satisfying upgrade.

I ordered this to have on hand for those occasions where I need to cut angle iron or pipe. I don't do that often, but I figured it would be faster than using a hack saw. I didn't really have any cutting to do, so I grabbed a piece of 1" conduit and a small piece of steel angle to make a couple of cuts. Goggles on, as steel makes sparks! The saw cut both materials well. Having a lot of teeth helps keep the cuts smooth, and even on thin conduit the burrs were minimal. Cermet will withstand heat, but will likely fracture if it starts bouncing around in cut, so feed the saw slowly and evenly for best results. The blade itself seems well made with chamfers on each tooth alternating from side to side (adds strength to the tooth and helps keep it from chipping on the corners). Pricing is about average for this type of blade.

This 6-1/2 inch saw blade performs exceptionally for steel, angle iron, and threaded rod, producing clean cuts with no heat buildup or excessive sparks. The thin kerf design reduces material waste and makes it lightweight for cordless saws, and the silver blade with black teeth is easily visible in the wild, making it simple to spot during setup or in my toolbox. It fits standard 1-inch arbors perfectly, enhancing precision for DIY or professional metalwork.
This blade cuts smoothly without binding, staying sharp through multiple uses, and the cermet tipping ensures durability. It's a great value for frequent metal cutting tasks. I'd highly recommend this saw blade to anyone needing a reliable, low-spark tool for safe, efficient results.

It’s a great value to get a 6-1/2" 48T metal blade at this price. It cuts metal fast and steadily. I’ve recommended it to my crafty friends!
