Are you trying to remove the freewheel from the hub or service the mechanism inside the freewheel?
Also there seem to be many different types of freewheel tools. What's the correct one for a road bike?
To remove the freewheel from the hub, you need the tool specific to your brand and model of freewheel. Some inexpensive single freewheels are not designed to be removed, and must be disassembled and destructively removed. What do you have?
