Did I just ruin 500 223 cases trimming too short, or are those still good?

I've never seen nor heard of this happening until now.

I always measure the first couple after trimming, and if I do a lot, every 50 or so when I take a break.

I have trimmed literally thousands of cases with the Lee system with nary a problem.
Even some tough trimming jobs, like removing .070 from a 300 Win Mag case to make 308 NM.
Never had a cutter eat into the length rod since Lee replaced the Aluminum rods with steel ones.
That was a long, long time ago, lol.

Is this the Lee Zip Trim?...I'm in need of a good case trimmer and am unsure of what's available and for how much. I have considered the Zip Trim, though. I'm just getting tired of the tedium and sore hands from trimming by hand.

answer from lee:
if using press drill, use lowest speed possible because if you don't, heat will anneal the cutter and steel and ruin it.

best cheap volume option to me is lee on a press drill. will see how it lasts at 500 rpm.

that hornady case prep trio is super great to chamfer and debur btw.
