The biggest difference you'll see should you get some ODHT0504ZZN-G88 in grade WK10 or WXN15 is reduced load, not a hugely better finish. Because those inserts are fully ground and dead sharp, they cut aluminium easier. This matters on a lot of machines which have greatly reduced spindle torque at the higher speeds. If you're successful and happy with the results you have with those very "universal" inserts, no need to be in any hurry to find the sharp inserts.
