TOMAX 12” 100T TCG Aluminum/Non‑Ferrous Blade
This TOMAX 12-inch, 100-tooth TCG blade is made for aluminum and non-ferrous metals. The triple-chip grind helps fight galling and keeps edges clean. The high tooth count leaves a smooth face that often needs no sanding. It fits a 1-inch arbor and works well on most 12-inch miter saws built for non-ferrous cuts.
I like it for picture-perfect trim, glazing frames, and aluminum channel. Chips clear well with proper wax or lube. Feed slowly, keep the work clamped, and you get straight, quiet cuts. If you cut a lot of thin-wall stock, this blade earns its keep fast.
Pros:
- Clean finish on aluminum, brass, and copper
- TCG tooth holds up against soft, gummy metals
- High 100T count reduces burrs and tear-out
- Good value for frequent non-ferrous work
- Stable plate for smoother, quieter cuts
Cons:
- Not designed for steel or ferrous metal
- High tooth count can slow feed rate
- Needs proper lube and chip control for best life
My Recommendation
This is a strong pick if you do railings, fascia, and shop fixtures in aluminum. If your goal is the best 12 metal cutting blade for miter saw use on non-ferrous stock, this blade checks the boxes. It is best for finish work, thin extrusions, and accurate miters. It offers solid value and is widely available.
| Best for | Why |
|---|---|
| Aluminum trim and extrusions | 100T TCG leaves a fine, chip-free edge |
| Brass and copper projects | Triple-chip grind resists smearing and loading |

TOMAX 12” 60T Steel/Ferrous Metal Blade
This 60-tooth TOMAX targets steel and other ferrous metals. The tooth geometry and plate are built to take on harder stock. On the right machine and speed, it makes cold, fast cuts in angle, pipe, and mild steel bar. It fits a 1-inch arbor and is a budget way to step into steel cutting.
Important: always match blade RPM to your saw. Many steel blades want slower speeds than wood miter saws allow. If your saw has speed control or is designed for metal, you are in good shape. Use firm clamping and a steady, slow feed to extend life.
Pros:
- Cuts mild steel and ferrous metals
- 60T count balances speed and finish
- Solid value entry into steel cutting
- Durable plate for straighter cuts
- Good for angle iron and pipe work
Cons:

FAQs Of best 12 metal cutting blade for miter saw
Can I cut steel on a regular 12-inch miter saw?
Only if the blade and saw’s RPM match and the saw is rated for metal. Many steel blades need low RPM. Check both manuals first.
What tooth geometry should I choose for aluminum?
TCG (triple-chip grind) is best. It resists loading and leaves cleaner edges on soft metals.
How many teeth are best for non-ferrous metals?
For fine finish, 96T–120T works well. For faster cuts with good quality, 80T–100T is a solid range.
Do I need lubricant when cutting metal on a miter saw?
For aluminum and plastics, a wax stick or light lube helps. It reduces chip weld and heat.
Why do some steel blades have low max RPM?
Cold-cut blades manage heat and chip load at lower speeds. Running them too fast is unsafe and ruins the blade.
Final Verdict: Which Should You Buy?
If you cut aluminum and non-ferrous metals on a standard miter saw, choose the Diablo D12120N 12” 120T. It pairs high RPM limits with a top finish. It is my favorite for daily shop work.
If you cut mild steel on a metal-rated or slow-speed saw, go with the Diablo Steel Demon D1280CF or 12BLADEST 60T. Each can be the best 12 metal cutting blade for miter saw users who match RPM and use proper clamping.
