Not necessarily. There are several to choose from. For very old bottom brackets, you need a pin spanner, fixed cup wrench and a lock ring wrench. For square taper bottom brackets, you can use the 20 tooth bottom bracket tool that is used for ISIS and Octalink. However, some of the tools made for square taper can't be used on ISIS type bottom brackets because the spindle won't fit in the tool. There are also 8 notch bottom brackets which need their own tool. Some Campys need their own spline tool. Finally, external bearings take their own tool.
