It depends.
Different threaded bottom brackets take different tools. Campagnolo uses a cassette tool for many of their traditional bottom brackets while Shimano did it's own thing. ISIS bottom brackets take a different tool. Most of the external bearing models seem to share the same 16 spline tool. Just get the special tool.
While press-fit bottom brackets (BB30, BB90, etc.) can be installed using a headset press it's possible to use a mallet and block of wood to spread the load.
