Topic tags/keywords: question

I keep hearing people say dado blades are dangerous, but never heard the reason why. I use a dado blade all the time and have never felt that by doing so, I was placing myself in danger. If there is something I don’t know, please enlighten me.

I would guess because some people attempt to do too much with them and are subjected to powerful kick back forces. Plowing a 3/4”x3/4” dado through oak is probably overdoing it.

The way I use them, I’ve never had any incidents. I just keep the cuts shallow enough that I’m not feeling any strong resistance to the cuts. Deep dados are done in multiple passes.

I’ve never had any bad incidents using a dado set. I’m curious to see what the responses are to your post. Like JAAune said, using a dado improperly can lead to problems just as with many other tools.

Probably because of the amount of material removed in the event of an accident….a full dado stack could really mangle flesh.

Using a dado blade can be as dangerous as using a plain blade, but why such a strong reaction by European safety associations? I can just see “VERBOTEN” printed in saw owner manuals.

“VERBOTEN” is “forbidden” in English for those that haven’t looked it up yet. My only guess is that the safety police in Europe are jumping on the US attorneys band wagon of thinking all consumers are entitled to be compensated for their carelessness. I assume their reasoning is that you have to run it with the guard off.

They are perfectly as safe as any other tool if you are careful and use common sense.

speaking of dadoes and potentially being unsafe, I have a question…
Im building a simple tv stand that will have one shelf in the middle. This shelf will be glued to the sides having dadoes about halfway up. My question is as follows, is it safe to cut the dadoes (for 3/4” plywood) crosscut wise on the table saw using the fence?
Before you think me a noob about to do something unsafe let me clarify the following, the pieces that will get the dadoes aren’t actually that much longer than they are wide: 20”X17” with the dado being put up about halfway up the 20” length. I have a stacked dado set that I just got, but wanted to get others’ inputs before I try this. Otherwise I do have a 1/2” router bit that I could use with two passes but it just seems like that would be much more of a hassle since I dont have a router table yet.

Europeans love their riving knives which don’t work with dado blades.

Everything we use can be dangerous if you aren’t careful. That’s why woodworkers are very common in the Emergency Department. Know your guidelines and follow them.

In addition to taking a bigger chunk of flesh, the skeptic in me also thinks someone who was well positioned to profit from it probably made tons of money by passing those laws in Europe. Greed and the urge for the few to control the many is pretty is an ugly part of human history.

Dado sets are perfectly safe… As long as you’re using them on a Saw Stop.

Sorry. Couldn’t resist.

In the past 5 years I have been using my grandfather’s craftsmen table saw and it has a ¾ hp on it .
But I do all my dado’s with it but I only go a ¼ “ deep and a ¼ “ wide and that’s Oak too. I wont try this on my big saw it has a 2 hp .
