Does faster rim speed on bigger blades make cleaner cuts?

And your current saw is able to accept a 12” blade? Table saw, miter saw, what saw?????

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.

I haven’t found that the higher rim speed cuts that much different. Blades are rated for certain rpms for safety. Too high a rim speed will generate more heat and dull carbide faster. Not a problem with a 12” blade compared to a 10” blade.

Do you have a Forrest Hi-AT Melamine blade? If so it’s one of the best blades for melamine. A zero clearance insert doesn’t make it perform any better and I much prefer that blade over a traditional triple chip and pre-scoring blade found on panel saws. It would be cheaper to bore it to fit your saw and different bushings are available to use on different arbors so you can’t lose.

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.

The Hi-AT is a great blade. The problem with the pre-score blades is if the Melamine sheet isn’t pressed flat and makes contact with pre-score blade you get chip out. The Hi-AT doesn’t have that problem.

Thanks everybody.

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.
