The original Hollowtech cranksets were 3-piece cranks with an Octalink cartridge bottom bracket. Octalink was Shimano's proprietary version of a splined crankset/BB interface. There were others like ISIS, which were similar. You can generally use the same crank puller for these different splined interfaces.

The Park Tool CWP-7 crank puller can be used to remove the crank arms from the spindle. If you use a tool like the CWP-7 that can do square taper and splined cranks, be sure to use the wide plunger for your splined setup.

A Shimano cartridge bottom bracket tool like the Park Tool BBT-32 can be used to remove the bottom bracket from the frame.
