Ghost Rider,

I can't say that it is not possible, but I have not experienced either of the issues you mentioned. I don't drill all that often, so I may not be the best person to answer that question. On the hand, when I do have to drill I don't drill in short bursts or use resin to cool the bur like some technicians do, so if either the glass dust or melting glass was a problem you would think it would happen to me.

Since the question will probably be asked, I don't drill in short bursts because in our testing it is not necessary and there is no benefit, and I don't use resin as a coolant because I have not found that it is necessary and in fact seems to slow down the drilling process for some reason.

I suppose it is possible that the type of bur you use could cause over heating issues, but again, I have not experienced that problem with the burs we use.

I would be interested in hearing from any of you that use diamond burs. I have been told using resin to cool the bur is essential with diamonds, and I have tried them using resin as recommended, but in our testing they just don't seem to cut the glass as well as carbide and don't last very long at all.

I only use carbide bits from Delta. I have tried DIAMOND and found no difference other than they cost more and don't last long.

My concerns would be bur breakage, doing more visible damage, and not anchoring a crack in the right place-drilling and popping and the crack jumping on me as I wasn't far enough away from the TRUE end of a crack. I use an extremely small bur to keep additional damage to a minimum.

I used to drill every repair.
Now I prefer not to drill.
My biggest concern is leaving as small a scar as possible.

I forgot about this post...

Thanks for all the replies and some feel the same as I do. It is also my beliefe that drilling depth is infact the most unknown concern /varible we all face everytime we drill. Thanks again.
