I have a nice Seco parting tool but the inserts are crazy expensive. They are marked TGP45. Does anyone know if I can buy inserts from someone besides Seco?

These aren't THAT expensive. I paid $190 for that box of 10 but will be looking for a new parting blade before I buy more.
Anyone got a Chinese parting blade system your are happy with?

I'm using MGEHR system John in 2 & 3mm width. I was sampling toolholders from here & there, coated vs uncoated inserts so a bit of a mish-mash sources wise. I also had a requirement for both left & right handed shanks which these have. This may have been one on of the sellers but I'd have to check my notes.

Ali link. There are many! Anyways shows a chart of shanks & cutter combbos. I always just get neutral inserts.

I was actually fully expecting them to be cheesy duds but its not like I was risking a lot of dollars. They are my go-to parting tools now. The one I reserve for aluminum is as sharp as when installed, its done a lot of work. I haven't done heavy plowing in any tough steels but I use the regular yellow coated ones on mild steel like 1018 & 12L14. They also did a nice job on 303 SS. Occasionally I break out a HSS blade if I have to grind a profile or oddball width so still nice to have. The other option in HSS is the T-blade which personally I prefer over the double taper type. The problem is usually the knockoff HSS toolholders can be iffy. USA ones are good but expensive new.

Just to complicate your decision, you probably have a nice toolholder. You can get also get knockoff blades/inserts but they will be different that the Seco. Not sure how the nominal blade holder dimensions stack up to yours though.
