I'm in Gardner MA, some 30 mins north of Worcester.
I have bits to drill holes of three sizes. 3/4", 1" and 1.5". They are metric sized bits for the heavy duty sched 80 bulkheads (slightly larger in diameter hole). But the holes work just fine for the regular duty bulkheads. I've drilled a 20gal and a 125 gal tanks rather recently. It was quite easy to do.
If you want to swing by with the tank send me a PM. I'd be glad to help out. Also, if you need to silicone in an overflow or something, I have some spare RTV103 (black silicone adhesive) you are welcome to use. I just built a 'bean' style overflow with the stuff on the 125. The stuff worked really well.
Oh and no charge for drilling. Easy to do and I'm glad to help a fellow reefer.
