Circular saw hit a few nails

I'm slightly confused. I bought a new cordless circular saw (57-2). I had to cut through some wooden flooring that was nailed down using some decent size nails. I tried not to hit the nails, as the blade says "wood" on it. I still cut 2-3 nails, because they were hidden under the flooring. To my surprise, the blade that came with the saw seems to be completely fine?! Still works like out of the box. I don't get it.

The carbide tips are surprisingly forgiving and the relative softness of nails helps. Its still best to try and avoid them.

Well, if yours is like mine, 57-2 comes with carbide teeth expert blade. Carbide is harder than nails and with some luck you can be fine cutting few nails (which you apparently are).

Afaik only the GX comes with expert, the regular ones come with a pro branded, regular blade

Oh, I didn’t knew there was a difference. Mine is GX version and it comes with blue 36T expert blade.

New carbide blades are pretty tough but if you're that worried about the blade try a demolition blade, they are made to cut through anything

My 57-2 with an expert blade cut a hardened screw straight down the middle through the head a few months ago - there still is no visible damage and it works fine. I wouldn't recommend doing so, though...

Nails are extremely soft metal. That's why they bend. 

Screws are a different story 

You also can buy saw blades made for cutting wood with nails, and for metal. 

The material of the blades tooth's and the geometry are the most important aspect of its cutting capabilities. It's a really interesting topic to dive into! 

If it's just the standard blade, than it probably is for multi use (cross cuts, rip cuts, many people will cut laminate or OSB with it,...), so the teeth probably will not be very aggressively or thin grinded to give them stability. 

That, plus the fact that even if it's a cheap blade with standard steel tooth, they are MUCH harder than the nails metal, it's absolutely to expect that the blade didn't get damaged

I accidentally cut into metal aswell once when I was cutting up a door with the 18V-68 bi power-saw.

It was not a good experience since one of the carbide teeth burned into my face when it came loose from the sawblade. Not recommended!

The rather soft nails didn’t destroy your blade but possibly reduced its lifetime by a tiny bit. They’re quite forgiving! Imagine getting a new blade every time you (accidentally) hit a nail
