Very narrow for parting, unless for special purposes, it will be very difficult to identify them as so many are proprietry, as far as I know parting inserts only go down to 1.5mm. I have some Kennametal grooving inserts which go very narrow, but only at the tips, the main body is much thicker, their maximum depth is limited.
