An Arbor press is also handy for removing mounting pins/collars from pneumatic actuators and setting bearings in slightly undersized holes.

A one ton arbor press can be found for under $100, it really one of those basic tools that any reasonably well equipped FRC shop should have.

A drill bit is too long for the job; it's subject to column buckling with high axial force (Euler formula). You can make a short pressing tool on your lathe for a specific job. When in a hurry I have found a steel bolt the correct sizes works well enough.

I believe he was trying to drill it out, not press it out with a drill bit.
I've seen videos of people hammering them out and in before, but if it's possible to press that sounds much easier than whacking at it.
