My used SS came with 3. The red is the locking version. The two black ones cant really be used because I have to re-level it when switching between them, major pain.

I was going to buy the Colliflower ZCI but was reading that Dado can trip the brake. How do you cut the slot for 45 bevel inserts and dado inserts? The benefits of the Colliflower is the removable inserts but if cutting the slot for a bevel is dado stack OR a bevel dado is not possible then whats the point?

the old Craftsman T/S that I have has the throat plate slightly deeper
than the 1/2” plywood available today. (which is not a true half inch).
I bought some 1/4-20×1/2” hex screws for the zero clearance inserts
so I could adjust them accordingly. I do not remove the screws when
changing inserts – each insert has its own permanent set of adjusting
screws and will always be true and flush with the table when switched around.
the screws hold amazingly tight in the woodgrain and do not come loose.
there are no “T-Nuts” used on the underside of the insert as the hex screws are self-taping.
I’m sure the same technique would work well with the 1/2” plastic cutting board,
King Starboard, HDPE, or whatever material you choose.

I used to build ZCI’s for my old tablesaw, but not for the Sawstop. The factory inserts are just superior to others in every conceivable way. You’ll need one for a combination blade, one for a 3/4” dado stack, and if you make dado cuts with the blade tilted you’ll need a third for that. Expensive I know, but just bite the bullet and get the good ones.

I’ve been using the SS version for a few years and no issues. I like the lock down mechanism. I also have the dado version too. It’s cool but only down side, you can make that dado slot bigger but not shrink it.

A couple of thoughts about Throat plates for SS. One – I recently purchased the Infinity Zero Clearance Insert (ZCI) which is an aluminum frame and takes replaceable inserts. It’s very well made and reasonably affordable (around $100 with 2 inserts), and Infinity guarantees that it won’t trip your SS brake. I may make a bunch of inserts for it, though the inserts come in a 4 pack for $15 (+/-). It’s really nice, well made, nice height/level adjustability.
Second thought – if you want to extend the life of your SS brand insert, run some blue tape over the top of the kerf and fill it underneath with BONDO. Then pull off teh tape and treat it like a new insert…remove the riving knife, hold the insert down with your fence, and raise your spinning blade – Viola!

I have the Infinity insert and it is the one I use. But, I find the inserts don’t fit well. They stick up a little. I have found I don’t have that many configurations and probably if I had it to do again, I’d just have bought a few more of the SS inserts. Certainly if you are going to work with a lot of different blades and dado widths, the Infinity insert is a good, though not perfect, way to go.
