A Floor standing pillar drill will certainly do it
I've never seen a drill table that doesnt tilt so just set it over to 90 degrees then you could clamp the length to the table and drill away
To make it easier place something down below to rest the 500mm length on whilst you are clamping

The fixture that NJH describes is fine but only if you want all your holes in the centre or anywhere else that its been made for
If you want one of those making I can do it for you
