Bought a new sawstop. My freud 24 tooth rip leaving some teeth marks on edge. Bought two CMT blades highly recommended by skilled woodworker on internet. this is when I began noticing the teeth marks. Went to Woodcraft to try their sawstop. Their Freud 24 tooth worked perfectly. My CMTs left saw marks. Brought all the blades home. Woodcraft’s freud was near perfect. My fairly new freud left more noticeable teeth marks. My 80 tooth old freud was near perfect. I own two Freud Fusions. Initially worked perfectly. Eventually performance was not as good. The saw sharpener said the face of the blades was not perfectly flat. He repaired them and they were better. Then they got worse again. I’m just a hobbyist and don’t put the blades through the ringer. But now I’m confused.

My suggestion would be to check and then double check fence/blade alignment.

I have three Freud “glue line” rip blades that I use in my my old’ish Unisaw. Two are the regular/full kerf, the other is thin kerf. All my blades leave blade marks, but they are barely noticeable. And I mean barely as in you pretty much need to look for them. Every now and then I’ll adjust the fence and get the saw marks to all but disappear, but they come back, again barely noticeable. I believe the cause is or might be humidity playing with the sacrificial wood fence I have fixed to the OEM fence. If your saw is new it’s likely that you don’t have any wood on your fence so what I say might not be any help to you. Regardless, alignment is key.

I agree with Bill. Check the saw’s alignment. First, make sure the blade is aligned with the miter slots and then the fence with the blade.

I’ve never had to adjust the alignment of the blade with the miter slots on my SawStop. My SawStop blade to miter slot alignment was spot on right “out of the box.”

My fence needed some tweaking with those nylon alignment set screws (I have the T-glide “Biesemeyer Style” fence.) I think a fence alignment issue is the most likely item causing your troubles…

Also check that the throat plate isn’t high in one corner. It’s nice to have a great cut from the table saw but really doesn’t really affect most work. At least for me.
Good Luck

Fence is tight at rear. Measure precisely (use a caliper) and make sure back is kicked out a literal hair (typ 0.003”) relative to the same tooth.

Alternately, upgrade your fence if you can’t get yours to align.

Gotta ask…has the wood been jointed and planed?

In my woods class in college we were told to rip stock 1/32” wider than required and then joint that edge. Truth be told I don’t ever do that, it does sound like a fence issue. You could also inspect the arbor, blade washer and nut to make sure there is no foreign material that is pushing the blade out of alignment.

+1 check blade to miter/fence alignment.


The saw sharpener said the face of the blades was not perfectly flat. He repaired them and they were better. Then they got worse again.
This statement leads me to think the saw (and/or setup) is creating the problem.

As much as we like to think our new tool is perfect, often that is not case.
Have you checked the arbor, or more likely – flange washer for run out?
If flange washer has run out, or the blade washer on outside is not flat; could be warping your blades as you tighten the arbor nut. This would contribute ‘they got worse again’.
This web page explains how to check and flatten the flange washer:

There are other methods posted on LJ and elsewhere on this adjustment.

Best Luck.
