Hey Guys,
So, I just bought a new Freud Thin Kerf Premier Fusion blade yesterday and installed last night. I also started cutting some MDF to make some small boxes for a work project.
Even though the blade sits a true 90 to by table, it seems the blade bends some how and makes a slightly angled cut. It also seems to be binding on the back side of the blade when i’m finishing a cut, but my fence is square to the blade before start making the cut.

Are there stiffeners for blades?
Any advice as to what may be causing this?

I run those blades all the time. I use a blade stiffener and have my fence set just a tiny bit open in the rear.

I just installed the same blade on my saw last week, and it cuts like a hot knife through butter.

I do have a blade stiffener installed, but I’m surprised MDF would cause blade deflection, even without one. I guess we’ll see what some of our blade experts have to say.

make sure blade IS square to the miter slot…then the fence to the miter slot..I don’t square my blade to the fence…I square everything to the miter slot…you can’t go wrong…the blade must be raised and squared to the table also.
If, then you have issues, the blade is shit. Buy a Ridge Carbide.

I use ‘em as well without a prob. Used stiffeners on the old RAS, but not on the TS. Could be that ya have a goofy blade? Might wanna contact Freud about the issue. See what they suggest. They have great customer service based on my experience. Ask for tech service not just sales folks.

also, i do not use or need a stiffener, don’t need it…I use a Ridge 10” 3/32” thin kerf. Sharp as a razor. In MDF, it’s cardboard max pressed to a hard sandwich…it’s BRUTAL on blades…hot! I hate MDF, but we use it, so…buy a Ridge Carbide and relax.

TheBryon – Wow…I’m no blade expert either, but it sounds like excessive blade runout. Take a combination square and set the body against the miter slot and extend the blade to the behind the gullet on the Frued. Spin the saw blade by hand and see if the Frued contacts the square at a full rotation. If not, remove the blade and check to see if there is debris on the arbor flange, reinstall and repeat the test with the square….or it could be arbor runout….??....good luck !

If the alignment checks out, and other blades work properly, I’d say it’s the blade…..defects happen. Contact Freud or send it back as defective and get a replacement.

I have an old Dewalt saw with the rack and pinion fence. The fence skips a gear occasionally and causes the blade to rub on the backside. You probably have a similar problem.

Didn’t you just get a new Rigid table saw? I remember your post about blade selection. Try to message some of the responders that recommended the Freud thin kerf blade directly and ask their opinion since they are familiar with the blade/saw setup. As no blade expert, I still recommend using a stiffener with all thin kerf blades based on experience only, with no empirical exidence to support that opinion. When I used thin kerf blades on my old underpowered saw, the stiffeners served me well. One downside: they reduce your maximum depth of cut. Good luck, work safely and have fun!
