Dado Blades

I recently purchased a set of Freud dado blades. I bought the 8” Super Dado. I feel as though they became dull quickly. I feel like I should’ve been able to get much more use out of them before they needed to be sharpened. Anyone else experienced the same?

What were you cutting, plywood?

Plywood could accelerate the wear on the blades, but if not, that does seem strange. Are they clean and free of any built up gum or sap? Also if making a 3/4" wide pass, it will use a lot of power on the saw, if only a 1 HP motor. Could be several issues combine, but hopefully not premature dulling.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

How long did they last sharpened? After what time did you notice changes?

Would you please elaborate. Just how many hours did you use then before you felt they were getting dull? What were the symptoms that made you think they were getting dull? Were you cutting different types of wood.

I have two sets of Freud dado blades for years. Never needed sharpening.

That said, the postitive hook angle set which I bought for my table saw tears up plywood. I generally use my negative hook angle set which I bought for my radial arm saw. A much cleaner cut.

How are you determining that the blade is dull?

Tearout on plywood is not a good indication. You can make a scoring cut and then make the actual cut. That will minimize the tear out.

I have heard there are fakes being sold but it's been a while back. I don't know how to tell them apart.

I did that once. It would be hard to mistake that for a dull blade. Plus all the noise.

For years I've used a local guy to sharpen blades. Unfortunately, he passed away some months ago and I haven't yet selected another sharpener (there aren't so many around here as used to be). I've looked at Quinnsaw's site (and a couple of others) but wonder about shipping/total cost for the service; maybe best to just send a couple of blades in for trial.
