Topic tags/keywords: dado broken blade repair

Hi Everyone,

I’m going through the slow process of teaching myself woodworking and I made a newbie mistake.

I purchased on Oshlun 6” dado blade set from Amazon, and thought that my standard throat plate was wide enough to use on 1/4 inch dado cuts. It was close…. but too small. The when I turned on the saw most of the teeth on the outer blade broke in half. I’d hate to have to buy a complete new dado set, since 7 of the 8 blades are still good, but I can’t find anywhere to buy a replacement outside dado blade. I looked into getting the teeth repaired, but that will cost almost as much as a new dado set.

Anyone have any idea where/how to get a replacement blade or if there’s any work around? (All the 6” blades I could find on amazon had 1/2 arbors instead of 5/8’s of an inch).

Any help would be appreciated!

Try giving Oshlun a call, and tell them what happened….maybe they can help.

You’re right a good sharpening service can braze new teeth on. A dado set has to be sharpened together to ensure flat cuts.
If you could get a new blade, You’d still have to sharpen the set
The cost would probably be close to what you paid.

Unless you can get another blade from Oshlun, I think you are screwed. You need to make an insert out of something besides steel.

If it is new then I think you’d be fine if you can source a replacement. I doubt that Oshlun individually shapens each dado set.

Per Oshlun website how to contact:

Thank you for your interest in Oshlun, Inc. If you have any questions or need any product assistance, please call us at 702-294-1231 or email us at You may also fill out the below form and we’ll get back to you quickly.

I checked with my Amana dado set one time, and it was cheaper to replace the set than to but a replacement outer blade.
