I do the "sideways" bit also when cleaning the entry. Kind of similar to using a sander around wood edges.
Gentle touch because too much is way too much.
Like me, I'm sure you use the proper amount of finesse with a delicate drill application.
Frankly, in the past, I've chipped more glass using a probe than I have using a drill to clean an entry point.
But, I DO use beveled burrs rather than rounded.
They break a lot easier but force one after repeated use and experience to exercise caution and control while using them.
I guess my original question about the advisability of just throwing caution to the winds and discounting the questionably and arguable idea of supposed esthetics remains unresolved when it comes to drilling.
I drill anything other than a bullseye and even with those I scrape drill or use a probe as a last resort after "side scraping" with my drill to remove loose glass shards and exterior or imbedded contaminants.
Years ago, the size of the burr convinced instructors to suggest foregoing drilling because that resulted in a hole in many cases larger than the original impact.
The drill/burr sizes available today cause that advice to be antiquated in my opinion.
I drill and I drill for what I think are many good reasons.
I remember when drilling wasn't even an option but I'm sure pleased that someone came up with the option upline from me.
Drill; don't drill.

Back to the original topic...
I pretty much drill everything but bullseyes too. But I don't drill "deep" that much. Maybe halfway into the glass or so is enough for most breaks. These "burr depth" holes I think are rarely a cosmetic issue. You have to really scrutinize the finished repair to notice a difference between this drilled repair and an undrilled impact pit.
The deep drill holes do have some cosmetic effects. They don't look bad if finished right, but it's not as good as no hole to fill. Also, pit resins are not perfect and they will eventually lose some of the clarity and good looks from when it's fresh. And please don't dog me and say I need better resin, etc... it's just a fact. It may be a several years or more if you have good resin, but it some day WILL NOT look the same as the day you did it. Unless the car sits in the garage all the time anyway.
Maybe I'm a drillaholic.

Hey Jeff,
There is no problem technically. The problem is theoretical. Before I didn't have to decide on which burrs to use. Now I'm stewing over using the 170 instead of the 1157. Its a life altering decision that one must not take lightly. Before I didn't know the 170 existed, now it may become my primary burr. See the mental anguish Delta has caused me.
Decisions....Decisions....

I love to DRILL : 
I usally carry two or three drills with extra batterys with me just in case I need one. I allway carry extra drill bits too. I am thinking now that I might make my mark at the edge of the glass so when a customer comes back I can tell it it was my work!!! and not any bodys else.
Has anybody broke there bit off in the drill hole? It has happened to me
How do you get it out ??

Re: Austin Hotels
GRT,
I do believe that you can receive full disability for this mental anguish!!! Wasn't life so much simpler when maintaining your transportation meant providing oats, grain, hay, water and some farrier work?
I have yet to have any network attempt to steer my equine related business from one veterinarian or farrier (blacksmith) to another;)

Unless you carry a pair of thin-nosed pliers in your kit (I do) and the broken bit extends out far enough to grasp it, just go ahead with your repair but don't try to charge the customer extra for the broken drill bit imbedded in their w/s.
I'm quite careful as to the angle and stress on the bit when I drill and hardly ever encounter the problem anymore.
Nothing much else one can do unless you carry an elctromagnet and a generator in order to power the aforementioned.
