fishfreak83 · 08/13/2006, 03:59 PM

i want to drill my own tank and i heard you need a diamond core one inch drill bit but i cant find one any suggestions without ordering one?

Local hardware store? Expect to pay $50+ localy for a single bit.

The much cheaper option is the Hong Kong diamond hole saws on eBay.

I would not drill your tank with any old drill.

Make sure you use a press or gravity press drill. You sit the drill on a towel and it has feet or a large foot that sits on your tank.

Your best bet to do this is to get it drilled by a pro, its risky doing it yourself. You could crack it or make a junk hole.

A press or gravity press drill is NOT necessary. I have drilled hundreds of holes in glass tanks with a Black & Decker drill without incident. Do not apply pressure to the drill while drilling...let the drill bit do the work, and keep water running over the bit to keep it and the glass cool during the process.

I just ordered four from a guy in ebay. We're not allowed to post links to ebay but search there for diamond hole saw and you will see a seller called lau*** including the asterisks. Several on RC have bought from him and say they are good ones. I haven't recieved mine yet but they are on the way.

Make sure that the glass that you are drilling is not tempered.

I have purchased over 20 bits from him and they work great. You do not need a drill press. I use a dewalt 18v cordless drill and i cut the bottom of a disposable plastic cup and tape it to the tank with common duct tape and then fill with water and drill. Very clean and painless. I drilled a 180 tank to be used for my sump and used one of his bits for a 2" bulkhead. no problems. I did however cut the bottom of a tuperware bowl off and taped it to the tank to drill. Most tank sides are not tempered but alot of the bottoms are. Also if the bottom is already drilled they re-temper the bottom after the holes are drilled and you cannot drill new holes.

Patrick, I've actually found that a drillpress makes the job harder. Its just easier to work by hand.

Getting it drilled by a pro is generally ridiculously expensive, on the order of $30+ per hole. On smaller tanks, thats silly.

I disagree. You don't need a press, I've drilled atleast 4 holes with diamond hole saws with a regular drill. Make sure you go high RPM and low pressure and it cuts through fine.

Theres a seller on eBay called lau** .. I've bought 3 bits from him and they all worked fine.
