Description

The DEWALT DWA7770 metal cutting circular saw blade is engineered to slice through steel studs, rebar, and sheet metal with speed and accuracy. Its 12% titanium carbide teeth stay sharp under tough conditions, while the modified ATB tooth geometry reduces burrs and gives a cleaner edge. Expansion slots prevent heat buildup, and the tri-foil braze keeps each tooth anchored securely for long blade life.

DEWALT DWA7770 5-1/2 in. Metal Cutting Blade Construction

Titanium carbide teeth: 50% longer life than standard steel blades.
Modified ATB geometry: burr-free cuts with less vibration.
Expansion slots: dissipate heat, extend blade life.

Product Details

Cutting Tips for Metal

For cleaner cuts and longer blade life, use a saw with variable speed and keep a steady feed rate. Let the blade pull through the metal—don't force it. For sheet metal, make sure the material is backed by wood to reduce vibration.

Why Titanium Carbide?

Titanium carbide tips stay sharp up to 50% longer than standard steel and can handle heat better. That means fewer blade changes on the job and more time cutting.

Frequently Asked Questions

Can this blade cut steel?

Yes, it's designed for metal cutting and works well on steel, rebar, and aluminum.

What saw is this blade compatible with?

It fits circular saws with a standard 3/8 in. arbor and 5-1/2 in. blade capacity.

Do I need to reduce speed?

Most metal cutting blades work best at slower speeds—check your saw's recommended RPM and stay under the max rating.

No sparks

I used it to cut steel studs and it went through like it was wood. No sparks like an abrasive wheel. The blade still looks new.

The future of metal cutting

I've cut a lot of metal with abrasive discs, and this carbide blade is the future. It's smooth, fast, and doesn't leave burrs. On aluminum it leaves a clean edge. On steel, it works best with a slower feed rate. The teeth are hardened and have stayed sharp after cutting dozens of pieces. I only wish it came in more sizes.

Better than grinder

My son showed me how to use this on his saw. It makes less mess than the old grinder. I'm impressed.

Decent with technique

I replaced my abrasive blade with this for cutting EMT conduit. It is much quieter, but the thinner kerf binds if you push too hard. You have to take your time. Once I got the pace down, it cut fine. Not quite as user-friendly as the abrasive wheel for me.
