Freud TK303 vs. TKR303

[mojo_13]

I was just wonderin what the difference between these two blades is. I am looking for a blade for my circular saw and have decided on the 303 but found them on amazon and just wondered what the difference is. They are both $19.99 so any help would be appreciated.

Not familiar with that number but on Freud's other blades the "R" designation was the red teflon coating. Can't hurt to have it, supposedly keeps pitch and stuff from clinging to the side of the blade, easier to clean and lower friction. If its the same price, I'd get the "R"
