Is a table saw supposd to have a clutch?
I just got a used table saw and I notice the blade continues to turn for a long time. Isn’t there supposed to be some sort of clutch to bring it to a stop? I can’t believe no one thought of this before me.

There are no clutches but you can get a break that is so sensitive, you can just touch it with a hotdog and it will stop almost instantly so you don’t lose a finger.

No clutch on a table saw, most are either direct drive or a belt drive. Either case the blade will keep turning after the power is shut off from momentum. If safety is the concern, lower the blade inside the case.

Since it it not necessary to have a clutch to operate a table saw and no one wants to pay for something that is not necessary, no manufacturer installs them on their equipment. Another reason is that every part you add to a machine in another possible point of failure. There is “some sort of ” thing to bring it to a stop, friction over time. When you have your table retrofitted with a clutch then you can apply for a patent. I am not holding my breath.
