Circular Saw blade for the inevitable nail

[Raisedonadeere]

I have always used my circular saw where I expect to hit nothing but good wood.

But I have a project where I have to cut some access holes through two layers of subflooring and along the path of contact with the supporting joist. I will remove the visible nails in the top layer and cut just deep enough remove that layer but most likely will hit some nail heads in the layer below. I know I will be sacrificing a good blade as far as it being a good wood working blade after all that but I want a blade that will hang in there for several holes.

What is your approach to this. I admit I haven't done much research yet and will be doing so, but I find so often as I read these threads I run across a way of doing something that most likely I just would not have thought of. Some of them are real duh moments BTW

My approach to this might not be relevant to your situation, but here it is.

I watch out for new skillsaw blades for $1 or less at yard sales. I buy them whenever I see them. I throw them in a drawer in a tool cabinet I use for woodworking stuff. Some are better than others; I don't care, I'm after cheap price.

When I'm going to cut something that will sacrifice a blade, I go and get the cheapest looking one that will do the job correctly, and use it. If I have a previously used one with chipped teeth or such but still usable, I use it. If it gets ruined, I throw it away. If not, I put it back in there for another future use. I haven't had to buy a skillsaw blade at retail in years; I live off other peoples unused purchases that the dispose of cheap later.

In your case, I'd go buy an inexpensive carbide blade at Home Depot or such. The Diablo referenced above is about $10 at HD, it's about as good as you need for that job.

I'm with ssdave. I keep older blades around for this type of use. As long as they still cut, I keep them otherwise they go into the recycling bin. I have one that still cuts that is missing the carbide from a tooth, likely from a nail strike previously.

This may be a good time to buy a new good blade for your saw and use the current blade for the job at hand. Once done change out to the new blade for normal cutting.

Any of the carbide tipped blades will cut through nails just fine.

This is what I do on my Milwaukee worm drive. https://www.lowes.com/pd/IRWIN-Clas...igh-Speed-Steel-Circular-Saw-Blade/1000119667

Thanks Hugermoose for the info, that is probably what I will do. But I just bought a Milwaukee 2730 circular saw 6 1/2” blade for this and several upcoming projects. That is why I have no 6 1/2” blades. My old plug in saw is in another state along with the old blades which I normally would have used.

And sedate is my style so I just would not know about the demo blade.

With a little practice, you can resharpen a non-carbide tipped blade in a few minutes with a file.

Exactly.

Thanks, I watched the link and realized that the blade police would not be much bothered if I go ahead and saw where I know there will be a nail. Perhaps way back when teeth were attached differently I hit some nails and lost enough teeth to render the blade useles. The carbide tips just broke loose from the blade. I probably will try the blade that comes with the saw on this project since I had already intended to get a better blade for good cutting, probably a freud. That come from reports that the oem blades are pretty so so.
