I ordered and used the exact same one. It worked great for 3 holes! I didn't need or try to drill any more than that, but I've still got the bit.

BigAl07 · 02-28-2008, 09:36 PM

that does seem TOO good to be true! I mean WOW!!!

Octoman · 02-28-2008, 09:44 PM

They ship them direct to you from Hong Kong. They're all probably made there any way, just skip the middle man!

Varga · 02-28-2008, 10:00 PM

you can get cheap ones from LHS they will drill 1-3 holes and get tossed but they do work and pretty cheap

ok, thanks for the help everyone. i followed yall advice and held out. Cracker gave me a good idea, make a circle of play-do around the area to be drilled then fill it with water before drilling. it worked great for him, but since i'm enlarging holes the water would drain out. i was thinking of letting the water hose run on top of the drilling area. any other ideas? Oh, i will be going to HD to find those bits today.

JoJo · 02-29-2008, 10:53 AM

anyone have have a link to one, i'm not finding the right carbide bits

The carbide bits at HD made me nervous, but I guess others have used them. I used the one from hong kong with no problems and poured glass cutting oil (also available at HD) on it as I went.

I did try the carbide bits a while back from HD to drill out some 10 and 20 gallon tanks. I cracked the first one, but after that I got the hang of it. I purchased some plumbers putty and made a reservoir and filled it with water and kept flooding it with water from a bicycle water bottle to keep the glass shavings from falling back into the area getting cut
Using your hose just to dump water on the area should work fine, still make the dam around the area you are cutting to let the water build up a bit. Oh and I was told to put tape on the backside of wherever I was drilling to help prevent the glass from breaking apart when it fell out.

Thanks. JWarren that website is nice. Does this look like a good set up? Diamond Tool King

for (2) 1 1/2 bulkheads & a 2 3/8 drill bit totalled $40 before shipping

JWarren · 02-29-2008, 05:58 PM

It's a pretty standard bulkhead fitting. Just make sure it is the size you want to use.

JoJo · 02-29-2008, 06:05 PM

yea, 1 1/2" should work great. i'm a lil' nervous but i'm upto it. i'll be doing some more reading on drilling before ordering everything.

Have you checked out having someone else drill the tank for you? My LFS drills tanks and guarantees not to crack the glass or they will replace the tank.
