Diablo Steel Demon Cermet II 48T (7-1/4″)
This is my top pick for the best steel cutting circular saw blade in 2026. The Cermet II tips are hard and heat tough. They run cool on mild steel and stainless. Cuts feel smooth, with low sparks and a clean face. I use it on angle, flat bar, EMT, and sheet.
The 48T TCG grind gives a steady bite. It does not grab thin stock when you feed right. The kerf is dialed for corded and cordless saws. Noise is low for a steel blade. Edge life is strong, so cost per cut is great.
Pros:
- Long life Cermet II tips for steel and stainless
- Cool, low-spark cuts with less burr
- Solid 48T TCG for smooth feed and clean edges
- Works well on most 7-1/4″ circular saws
- Good balance for cordless runtime
Cons:
- Higher upfront price
- Not ideal for very thin shim stock
- Needs steady feed to avoid blueing on thick wall
My Recommendation
If you want one blade to trust, pick this one. It is the best steel cutting circular saw blade for most pro and DIY cuts. It shines on mild steel tube, studs, and 12–3 gauge plate. It also handles light stainless work when fed slow. I reach for it when I want a clean edge and low fuss.
| Best for | Why |
|---|---|
| General steel fab | Cool cuts, long life, clean edges |
| Cordless saw users | Efficient kerf and grind saves battery |
| Mixed steel jobs | Handles tube, angle, and sheet well |
HARDWIN 7-1/4″ 48T Cermet Metal Blade
This is a smart budget pick. The cermet tips track well in mild steel. It chews through angle iron, uni-strut, and studs. Sparks stay low and the edge needs little clean-up. For the cost, it is tough to beat.
The 48T count is a good match for most cuts. It grips without chattering when you hold a steady line. You get a 5/8″ arbor, so fit is simple. It is a nice backup blade in my kit.
Pros:
- Good value for a cermet-tipped blade
- Low-spark cuts on mild steel
- Clean edges for basic fab work
- Easy to control on 7-1/4″ saws
- Decent life for the price
Cons:
- Not as durable as top-tier pro blades
- May dull faster on stainless
- Quality can vary batch to batch
My Recommendation
On a tight budget? This blade makes sense. It is not the best steel cutting circular saw blade on Earth, but it earns its spot. I like it for light fab, fence work, and jobsite steel trims. It is also a smart buy as a spare for weekend projects.
| Best for | Why |
|---|---|
| Budget steel cuts | Affordable cermet tips with solid performance |
| Light fab and repairs | Clean edges without high cost |
| Backup blade | Good to keep on hand for mixed tasks |
DEWALT 7-1/4″ 16T Metal Cutting Blade (DW3330)
This blade has a low tooth count for fast, rough steel cuts. It works on thicker wall tube and steel studs. Fewer teeth mean bigger gullets, so chips clear fast. It is great for quick crosscuts and demo tasks.
The trade-off is a rougher edge. It can be loud and spark more on thin sheet. But when speed beats finish, it shines. If you fab heavy racks or cut scrap, it earns its keep.
Pros:
- Fast cuts on thick steel and studs
- Large gullets clear chips well
- Good for demolition and rough work
- Strong body resists warp
- Simple, reliable feel in hand
Cons:
- Rougher finish on edges
- Not ideal for thin sheet
- More sparks than fine-tooth cermet blades
My Recommendation
Use this when you need to move fast on thick stock. It is not the best steel cutting circular saw blade for fine edges. But it is a workhorse for racks, heavy brackets, and quick cuts. For shop clean-out or jobsite demo, it earns time and money back.
| Best for | Why |
|---|---|
| Thick-walled steel | Low tooth count bites hard and clears chips |
| Rough, fast cuts | Speed over finish with solid control |
| Demolition work | Durable edge for scrap and mixed steel |

This high-tooth blade aims for clean, thin metal cuts. The 68T grind makes smooth edges on sheet, studs, and flashing. It helps reduce burr and sparks. Feed it slow, and the finish will make layout easy.
You will like it for duct, roofing, and thin mild steel parts. It is not for thick bar. It is for detail and fit-up. Match the speed and keep your line. The result is pro clean every time.
Pros:
- Very clean cuts on thin steel

| Best for | Why |

FAQs Of best steel cutting circular saw blade
What size blade should I choose for steel?
Match blade size to your saw. 7-1/4″ fits common circular saws. 14″ suits cold-cut chop saws. Use 8″ or 4-1/2″ for special tools.
Is cermet better than carbide for steel?
Often yes. Cermet runs cooler and can last longer on mild steel. It helps reduce sparks and burrs with a smooth feed.
Can I cut stainless steel with these blades?
Some can. Use cermet tips, slow feed, and cutting wax. Go light on pressure. Avoid very hard or thick stainless on fine-tooth thin-metal blades.
Why choose a cold-cut blade over an abrasive disc?
Cold-cut blades give cleaner, cooler cuts and less dust. They cost more up front but save money over time. Edges need less cleanup.
How do I get the cleanest edge in thin sheet?
Pick a high-tooth TCG blade. Clamp the work. Feed slow and steady. Let the blade do the work to avoid heat and burrs.
Final Verdict: Which Should You Buy?
The Diablo Steel Demon Cermet II 48T is my top choice. It is the best steel cutting circular saw blade for most jobs, with cool cuts, clean edges, and long life.
If you cut thin sheet, grab the Diablo 70T D0770F. For chop saw work, pick the Evolution 14″ TCT. Choose the best steel cutting circular saw blade for your saw and stock, and your work will fly.
