That's the nature of two-notch freewheels. SunTour is much better than Regina and its two-notch copies (Everest/Caimi, Maillard, old Shimano Dura-Ace and 600, etc.), but it's still too easy to damage the tool, the freewheel, or both.
Don't use a Regina-type tool on a SunTour freewheel, or vice-versa, as the likelihood of damage is virtually 100%.
My experience is that SunTour's official freewheel tool is stronger than the Park, but the SunTour tool is getting harder to find.
