You have to keep the bit spinning pretty slow. I used plumbers puddy and made a little dam around the bit and poured water in the there to keep the bit dry. However, a 40g has much thinner glass and you probably wont be doing a 1" hole. So as some have said the oil lubricant is probably needed... i've been trying to get pics of mine up but my camera wont take pics that are small enough to post on the forums  |
next time use oil it will add life to the bit and lubricates better as well as cools
I use 3&1 oil or old cooking vegetable oil.
