ah yeah good call freezetyle, its been awhile but i have been f'd around by ups in the past..

thats good to here grizz, I was wondering actually how many holes your able to drill before wanting to replace a diamond hole saw. Ive heard even a few will dull the cutting edge, but i suppose it all depends on how deep or thick the glass is, along with how much lubricant your using.

Rona carries diamond hole saws (despite what the guy on the phone when i called to ask....) an in house brand called 'eco'. I randomly stumbled across these while looking at mitre saws in the hardware section. They have small hole saws all the way up to what i needed, 2.5"

Figured id let everyone know. Reasonable price too, 36.99 for the 2.5

I saw some hole saws at rona the other day. They were the bits you exchange when they are dull. I only saw bits up to 1 inch though. The rona out here is small maybe a bigger store might have bigger sizes.

Princess Auto is probably the best place to get them or ebay

It's cheaper there and works ok. I cut through 2 holes in about 1/2 inch of glass
1st hole was 1 1/2 hours, although my second hole almost took 3 hours to drill it was painful lol but that's almost 1 inch of glass total for one hole saw

I picked mine up at Rona which has a exchange program. I drilled 4 holes and returned it for a new one for twenty bucks
