I need to drill a new hole to fit my 1-1/2" bulkhead on my sump which is a 180G glass tank.
What kind of tool do I need? I hate to buy expensive tool and only use them once, any cheap workable tool available?
How easy to drill a larger new hole (for 1-1/2" bulkhead) on the same spot of a smaller old hole (for 1" bulkhead)?
