do i need thinner drill bits?

[jasonsresin]

i thought i knew everything and was the stuff (until i found this forum). i truly believe we are the best in our area, and at best, another vendor can tie us in windshield repair. however...

i would love to look into a thinner drill bit, as i just read the debate on drilling vs. non drilling, and i have no idea how thick my drill bits are but i thought they were pretty thin. i never knew there were different sizes but my wife commented before about wishing there were smaller drill bits so i could have a smaller pit. i said honey, this lets the resin flow better. well who knew she was on to something. what is the thinnest bit i can get from delta? is that the bit you guys use or do you stock different size bits in your toolbox? i would love to have a smaller pit to compliment the perfectly repaired windshield.
thanks,
jason

Have a look on the new Delta website and it gives you a list of drill sizes. In most circumstances it is the size of the piece of glass that is missing rather than the drill bit that governs the size of the pit. Where about are you from?

from maryland. you're from the uk aren't you? i'm guessing by the usage of the word screen

what are most drill bits? if mine are that thin now i won't bother. i get them from a dental supply place. but if mine are medium and he carries thin, i'm in! except they're twice as much per bit plus shipping... but i'm still in for a few!

I had some real thin ones not long ago (not from Delta) that broke if you spoke too loud, so that might be a consideration too

hmmm... that's what i told my wife when she suggested they should be thinner. they'd be too brittle.

Carbide burs are not all that expensive. Whether you try Delta Kits or purchase your burs from another source, I think it's worth experimenting. We will even let you mix and match a 5 pack if you want to try several different styles. We sell quite a few of the thin burs and have very few complaints.

How quickly you go through them will depend as much on technique, drill speed, and maintenance as anything else. I don't recommend the thin burs for drilling the end of long cracks if using the slide hammer or other tool for popping bullseyes, but if you don't use that method I would think the smaller the better.

In our testing, our largest bur, the FG701, is by far the longest lasting if you heat clean them after each repair, but the pear shaped FG329 is our smallest tipped bur and is quite popular as well.
