If you are rplacing the Bearings you can use steel punches because it does not matter if you damage the bearings.

When you install them is when you need the Brass Punch or even an aluminum one if their diameter is enough.

However, you can even install the bearing races with Steel Punches but you need to be extremely careful.

Note that removing and installing favors a heavy hammer that you don't have to move much.
A Hammer that takes a lot of velocity to provide force also cause the punch to more easily skid off and go someplace you don't want it to go.

I thought that Harbor Freight sold a brass punch that was about 1/2" in diameter.

All punches need to be resurfaced eventually.
