Do not use this blade. You are fortunate to have found it during the cleaning. The alternative way may have proved painful or even incapacitating. If the blade is not too old I’d contact Freud or try to return it to the retailer. If you feel that it has paid for itself then replace it. Whatever you do don’t try to use it, it’s just a matter of time before that thing becomes a projectile flying off a blade spinning at better than 4000 rpm. Not as pleasant prospect.

I’ve used it too much to return, I think. Bummer.

CharlesA,I have heard if the blade is not ground correctly ,the carbide teeth chip easily,now how true that statement is I’m not sure but if I noticed one tooth chipped off I would take the blade to a sharpening center and ask them to replace the tooth and then resharpen the whole blade correctly.

Disturbed is right it can be repaired. But don’t use it til you do. Imagine flying carbide finding your eye balls :-/

Id say contact freud and enclose picture of tooth problem, Im thinking they will either ask you to return blade at your expense or they will send a shipping label to have you return the blade. This is a danagerous blade and that tooth could dislocate with out even hitting any wood. Freud has enough problems Im sure they don’t want another so im sure they would nip iit in the but right away. To me it looks more like a defect that ruff use of the blade. garver brown

Send it too freud they’ll charge you a few bucks for a new tooth and sharpening.
Or send it to Forrest.

You probably hit some metal and caused the carbide to fracture.

I’d be very surprised if I hit metal. I don’t use it all the time. I have a crosscut blade and a 24T blade for more general ripping. This one gets treated pretty nicely.

Another plus for not using the blade. I’d contact Freud as well. They’re usually pretty good about getting problems resolved. If it’s a well used blade, it might cost you to have the tooth replaced, but you might get lucky and they’ll replace it or the blade for free.

I’ve never seen a tooth fracture like that without being hit somehow.
To me it’s not worth the time trying to contact Freud and shipping the blade off.
Regardless how it happened, I would just take it and have it resharpened and a new tooth put on, and call it a day.
I think my sharpening shop charges my 5 bucks a tooth to replace.

If Freud isn’t interested in replacing it, a sharpening service can replace that carbide and resharpen the blade much cheaper than replacing it. My sharpening guy always checks my blades and has replaced teeth I hadn’t even noticed were bad.

I’ve sent an email to Freud—may as well find out.

Kevin, you may be right—I just can’t imagine when that would have been given how I use it.

I had the same thing happen to more than one Freud blade, one time to a forrest blade. Freud wasn’t interested in talking about it. Forrest replaced the blade (but I had to pay shipping), I had not even used the Forrest blade, I noticed the carbide chipping off when I was preparing to install it. I been using Ridge Carbides for a couple of years now, no problems at all.

Called my local toolshop where I get my blades sharpened (local person comes by and picks up/drops off once a week) and she’ll replace a tooth for $3.90. Works for me.

I went ahead and got a new one so I’ll always have a sharp one. Since the sharpening service takes 1-2 weeks depending on when you drop it off, it’s helpful to have two of any blade I use a lot. I have two general purpose/crosscut blades, and now I’ll have two glue line blades.

That sounds pretty reasonable for getting a tooth replaced. It’s been a long time since I had one repaired, but I do remember it was a much better deal than total blade replacement.

That tip is not chipped. It is fractured and not normal. Chips usually occur at the corners, not down in the gullet. Contact Freud. Carbide is made in various brittleness grades and each manufacturer determines what the best grade is for his product. Your blade may have gotten the wrong grade of carbide. If that is the only bad tooth, you could have it replaced and resharpened.

Fractured. That is the word I was looking for. I knew chopped was wrong, but couldn’t think of the right term.

Did anybody look at the main blade part ? Unless its been repainted its new. That blade hasn’t cut I’ll bet more then a dozen pieces off from boards. I use to be a John Deere salesman 28 years and defects happen to anything. Freud needs to be involved in this, the way the metal is split I doubt you hit anything but wood. Maybe they got a bad batch of carbide, it happens. GB

If I showed you the label side you’d see that the black branding has been rubbed off near the teeth. I’ve probably made 200 or more separate cuts with that blade (hard to say). It’s not that old, but it’s clearly used.

Now, that may still be a manufacturing defect. I don’t inspect the blade up close regularly, so I have no idea when that happened. Wouldn’t have seen it at all if I hadn’t cleaned it.

I do not know how anyone can say how the tooth broke and not normal without seeing the fracture surface. Certainly, only seeing the side view is not sufficient to tell how it broke. I have done failure analysis on steel and metal parts and I can not tell form the picture.

Given the relatively low cost of replacing the tooth, it is not worth the effort to try to determine why it broke. It can take only one minor contact with something hard on a carbide tooth to cause it to break.

I have about 10 Freud blades and have had extremely good luck with them. The only problems are one where I hit a tooth on something and damaged it.

One can never be sure, of course, but since I only use this blade on final rip cuts on planed and jointed hardwood (no plywood or construction lumber), I can’t figure how it would hit metal. But since I don’t know when it happened, I won’t be doctrinaire about it.

Took Freud a couple of days to get back to me, but once they did they were very responsive—several email back and forth in the last hour. After looking at the pics, they agreed this was a warranty issue and was not caused by abuse, so they’re going to replace the blade.

BTW, he did mention that blade cleaners can weaken carbide. I hadn’t heard that. In this case the cleaner was on for 20 seconds before I noticed it, so I’m good there. He also said the type and size of the problem wouldn’t be caused by cleaner after he saw the pic.

Good to hear a positive response from Freud.
Did they make any suggestions on cleaner or a cleaning method?

Washing soda(not baking soda)one tablespoon per 2 quarts of warm water is the best cleaning solution in my opinion.

Glad to hear they are replacing the blade. I contacted them awhile back and it took a couple days for a response but they were very helpful and offered to replace my blade under warranty. But my problem turned out to be a worn belt, the blade was fine so I never sent it back.

I’ve used the blade enough that I thought it was borderline for me to complain too much. But it has a limited lifetime warranty against defects in material and workmanship, so it works out.

I was thinking of my email conversation with Jim from Freud and I realized it couldn’t have been caused by hitting metal. There’s no way a tooth could have damage that extensive from hitting metal with no damage to the tooth in front or behind.

Carbide would have cut through a nail or screw, maybe chipped an edge but I can’t see it causing splintering like that. Has to be defective. It’s a scary thought but if you figure that Freud is going through millions of little pieces of carbide a year there is bound to be some defective pieces no matter how careful they are.

I had a chipped tooth on a Forrest blade but that was my neighbors fault for cutting through a nail and it did not look like your bad tooth as there was a piece actually missing.

Job done then.It was maybe damaged by clanging against something hard ,maybe another blade in the factory. Tungsten while hard is very brittle always store your blades seperate from each other. Have fun Alistair

Freud’s suggested cleaning method: “The way we recommend cleaning of blades is by soaking them overnight in a sealed container of kerosene and then brushing off the teeth with a soft brush like a tooth brush. This is also the most economical as the off the shelf cleaners cost $4 to $5 for a few ounces while kerosene is under that for a gallon.”
