3/8" arbor with 10 mm arbor blade

[skon1212]

I have an older Ryobi cordless Circ saw that has an 3/8" arbor. I am trying to get a finishing blade for it to cut some trim. It seems that all the 5 1/2" blades have a 10mm arbor. Will they work? I have seen mixed answers.

3/8 = 9.525 mm , but I don't know if that's close enough.

It will fit but not run true. This may or may not be an issue. It depends on a lot of factors.

Never seen a trim blade for a 5.5" saw. It just isn't a precision tool.

I would get a high quality blade and go slow. 10mm will be the standard arbor size. I bet it will be fine
