Does faster rim speed on bigger blades make cleaner cuts?

I have a 12” melamine Forrest blade that isn’t bored to fit my
current saw. I don’t need 4” depth of cut when cutting
sheet goods, so I’m wondering if it might be a good idea
to sell off the 12” blade and buy a smaller 10” melamine
blade already bored out for my saw.

That said, the 12” blade would have a higher speed at the
rim and more teeth too, so the question is whether
that large melamine blade would be worth boring out.

And your current saw is able to accept a 12” blade? Table saw, miter saw, what saw?????
Help us help you.

Table saw. Yes, it takes 12” blades with no problem.

The bore is 30mm with alignment pin holes.

Thanks. I have an 80 tooth finishing blade (not HATB), but I don’t cut a bunch of melamine. Finish is good to excellent depending on material. I’d use the 10” for no other reason than cost. Rim speed vs: tooth count is a moot point if the cut is acceptable.

Loren, do have a prescoring unit on your saw?

The SCM slider takes a 12” inch blade but you have to change to 10” to allow for the scoring blade when panel cutting. so I would say the rim speed is not an issue.

It is a Forrest Hi-AT. I have never used it.

My saw doesn’t have a scoring unit. It’s a slider. There is a
scoring unit available but as with everything Felder, you
pay through the nose for the options. I’d rather make
do with the saw for now and get a large slider sometime
in the future when I get into a larger space.

If the plate on the 12” blade isn’t thicker than that of a 10” blade, I’d think the 12” would be more prone to flutter, but there are a lot other variables in play. Since the 12” isn’t bored to fit your saw, I’d sell it and look into a 10”....more affordable, and probably more choices.
