Since this seems to be a regular occurrence, I bought a strainer at
McMaster-Carr, item 9875K413. This is an awesome deal at $15, it is
actually large and can clearly do a great job trapping chips. It is
also easy to clean and replacement screens are available, not that
they are needed. I got one with clear bowl, so I cal see the situation
inside.

It shouldn't be. No chips large enough to clog your lines should ever
get into the sump.

I have 10-mesh screens at both table drains, then another finer screen
(14 mesh) on the sump return. I have similar tee fittings, and have
never had a clog. If you keep the chip size under about 14-mesh, they
just aren't going to affect the system, except for the occasional bind-up
at a restricting valve, which you can remove by opening the valve full-
bore, then re-closing it. I chose rotary valves for the reason that when
they're open, they're full open, with no restriction to flow.

I think the strainer is nice, but wholly unnecessary.

I agree with your reasoning. I have no idea how those chils could have
entered the line.

1. There is a mesh where coolant re-enters the sump.
2. The pump itself has a mesh screen.
3. I cleaned the sump pretty well soon after I got the mill.

And yet, I got this elbow clogged!

So, I hope that the strainer will help.
