I was under the impression tbh that you would of needed a cassette removal tool as that's the most commonly used these days due to very few wheels being manufactured with a freewheel hub since the late 80's so any way if the freewheel removal tool you've ordered is compatible with Suntour then i have a good feeling it should fit your chinese branded one and the Sunrace but in saying that their shouldn't really be much difference between the main brands with the exception of Campagnolo..
