Already removed the axil from both and original geared cog. Just looking to swap old cog over.

How can I remove the single freewheel cog from the wheel? Can I mechanically move this in an anti-clockwise direction using the holes? or What tool do I need?

It kind of looks like a pin spanner hole arrangement. Pin spanners get a mention in this video.

This is something I've done a few times. Those pin holes are actually holding the freewheel together. You can usually use them to unscrew the freewheel but sometimes they will unscrew and loosen the freewheel bearing. There are two notches in the centre, these are what you need to use, ideally with a tool which fits them but a hammer and punch or blunt chisel will work just as well. Hold the wheel beetween your knees with the freewheel to the right and place the punch in tightly in the notch and hammer it in an anti-clockwise direction. It will take a few sharp cracks to get it to shift but once it starts to move, it will probably unscrew by hand if the threads were greased when it was installed. Hit it hard, small taps won't do the trick.
