Bisect/knife/box select/extrude/scale not cutting through entire object

Hello, I’m a Blender noob and have researched several ways to cut an object.

None seem to cut entirely through the object’s base.
The height is 5.24 mm and I need a height of 3.32 mm.
I have to cut away to bottom of the base, as the top has detail.

Any assistance please?

Both the knife and bisect tools do cut through, although for knife you do need to enable cut through explicitly.

I think you must select all faces when using the bisect feature.
