1/2" and 3/4" bulkheads

[hvusalt]

want to drill my nano tank for my son and bought a wrong size diamond drill bit kit, can someone tell me what size of drill bit to drill these two bulkheads? anyone have that used drill bit for sale or trade or anyone drill a tank in close by area for a fee?
thanks

I have a 35 and 45 mm drill bit for sale. The 35 is for a 3/4 inch abs bulkhead and the 45mm is for a 1" bulkhead. I would double check on bulk reef supply for bulkhead drill bit sizes. That is where I bought my bulkheads and drill bits from . They suggest 30mm for a 1/2 inch bulkhead.

Best of luck
