Superman's Glass Drilling Demo Video

Nice video but couldn't you just use water to cool the bit? Would be a bit less messy/hazardous wouldn't it?
 
I have read theories of water getting into microscopic cracks that happen during drilling and because of the heat generated by the drilling the water expands within those cracks which causes them to enlarge and be a possible hazard down the road. I don't know if that is true, but I've drilled many tanks this way and won't change up my routine now. I also believe that the antifreeze works better as far as being "slippery" and thus being a better lubricant.

with steal work we use dawn dish soap alot to cool bits another idea, safe clean, cheap!!

Interesting, tell us how it is used.
 
I work in a machine shop that works with High Alloy metals, and I just grab some of the shop fluid that they use. Can't tell you exactly what it is, but I can try to find out if you want! If it can keep Titanium and Hastalloy cool while cutting at high RPM's you know it's good stuff!
 
Superedge,

What is that gunk around the edge you use to keep in the antifreeze... playdough?

Also, what diamond drill bit do you use?

Thanks for the video, very informative and makes it look not so scary to do on your own.

Cheers,
John H.

That is the one thing that I am kicking myself for not mentioning during the video, I use plumbers putty for the reservoir that the antifreeze sits in. The bit I used is from ameriglas.com though I now know there are places around on the internet that sell them for much cheaper.
 
I get all my hole saws from Richon Tools, they are out of Hong Kong I believe, after shipping mine was like 11 bucks and it was here in a week!! Most online vendors here in the states can't get stuff to me that quick. Also I drilled prolly 8 holes with the one hole saw! Just a FYI for anyone interested in ordering one.
 
I should order one from Richon Tools then, the bit I got from ameriglas is good for over 25 holes, it would be interesting to see what the difference in quality might be.
 
I have well over a dozen holes from a $10 eBay "hong kong" bit. These include holes in glass and PEI 5 rated solid ceramic tile.
