What is this blade for?

[Shawn Stennett]

Is this blade a combo blade?

[Paul Atkins]

Maybe - pull off the rubber and let's have a look at the teeth. Close up.

Is it me or is there some serious chunks missing from those teeth? Was that sold as new? I'd be leery of putting that on my saw.

[Joe Chritz]

Those teeth look a little rough. I am not sure where the raker tooth would be on an ATB blade but it looks like some parts are missing. You can see a flat tooth in between two beveled teeth. It looks broken in the pic.

Other than that it does look like a combo blade, everyone I have used has those open gullets after every 5th tooth or so.

It looks like it could be a full kerf Freud LU84M011 50T combo blade, or what's left of one...but those teeth look really rough. There should be a flat raker in the front of each group of teeth, followed by 4 consecutive alternating top beveled teeth. From the pic, it looks like 2 out of the 4 ATB teeth showing are broken....could be just the angle of the shot....

[Jeff Bratt]

It should be/was a combo blade. There are problems some of with the teeth shown in the pictures. In pic #2 - from left to right: the first tooth, with the larger gullet, looks to be a flat-topped raker tooth - it might be chipped, but it's out of focus. The next four teeth are the alternating top bevel (ATB) teeth, and two of them (#3&5) look OK, while the other two (#2&4) are badly chipped. If the other groups of teeth looks like this, the blade is toast. Maybe this blade hit something that chipped the right hand side of all the teeth??? Check out the rest of them...

[Shawn Stennett]

I cleaned it up and inspected it closly, I think that it was a combo of the angle of pic and it not being really clean. It is a flat then alternating angle.

[Mike Parzych]

Looks like the outside blade of a dado set.

Sure looks like the 4th tooth from the left in your second image is chipped.

Looks like a triple chip grind for laminate and melamine cutting.
I have one very much like it. Makes extremely nice cuts in MDF and other materials.
I think most are seeing crap you didn't clean off well. But there does seem to be glint from edges that shouldn't be there.
But the grind is most certainly a triple chip type.

I am not sure in the second picture shouldn't the angle teeth be alternating.
The third tooth and the 5th tooth are going the same way.

I don't know just asking.

[Tom Walz]

Here is what I get.

Square top chipped
Trapezoid tip
slant to the left
lower square top
slant to the left

The overall design looks like combination. The last steel bump looks like an anti-kickback feature.

Anybody agree or disagree

If that is correct it is a custom, one only blade someone made. Might not have worked. Might have been for a special application.

It is a combination blade, ATB+R grind - notice the 5 tooth grouping. Definitely not triple chip.

An ATB+R combination blade (needs cleaning).

Another ATB+R combination blade - for RAS or miter saw. High ATB angles, negative hook.

Triple-chip rip blade.

Jeff is correct. By the looks of the anti kickback it is probably a Freud LU85. It has definitely been run. How it got plastic on it makes no sense. I am guessing it was cleaned a bit and sold used, as is. It won't hurt any thing to run as pictured but do not expect very good performance until after a saw shop has done some work to it.
