got hole saws? (drilling sump)

[kari]

Sorry but I don't have the bits to drill glass.

ok, i need to get back on the horse with this project. Anyone? know of some good ones for a decent price in town?

i just got two off e-bay. they're diamond thk diamond bits. they come from korea. not super high quality, as the diamond's glued to the bits, but for $4 each, they're a solution if you're on a tight budget. took about 2 weeks to get here, no duty (shipped postal).

i'd offer to lend you one of mine, but i don't have the size you need unfortunately.

What size hole are you after? I gather a 1" bulkhead isn't what you want?

i want to do 2 x 1.5" bulkheads- so its like a 2-2.25" hole isnt it?

Sorry that I didn't read your first post where you said 1.5" bulkheads BTW.

The hole size for 1.5" bulkhead is I believe 2.5" (65mm), at least according to this page it's 2.5" (I'll check when I get home from work, I have some 1.5" bulkheads I can measure to be sure).

Anyhow I just came into a situation where I need to drill a hole for 1.5" bulkhead too, so I just ordered me a 2.5" glass bit. If you're still in need of getting the stuff drilled when this arrives, you can borrow it... I'll post back when I get it.

thanks tony- that would be greatly appreciated.

It arrived I haven't used it yet though since what I thought I would need it for, I was able to get away with using a 1" bulkhead and a bushing to step down the 1.5" pipe at the bulkhead - so it's all nice and shiny still

Anyhow if you're still interested in getting those holes drilled drop me a line.
