There are a few sites out there. Here are a few I've come across:
http://www.uniontool.co.jp/english/tech_01.html
http://www.megatool.com/
http://www.kyoceratycom.com/
http://www.discount-tools.com/technical.htm
http://www.tulon.com/
It would be difficult to go into detail about the different drill
parameters, backup & entry materials, different material / resin systems,
drill machines, drill bits, etc... The best way to deal with this is to
design a DOE using your equipment, drills, materials, and evaluate the
effects of different infeeds, spindle speeds, hit counts, etc... By
sectioning and measuring the aspects of the drilled hole wall quality -
smear, gouging, nailheading, burring, just to name a few. Hope this is of
some help.

Subject: Drill Bit Geometry Defects
Dear Technetters,
Is there any document or web site which has information about the different
drill bit geometry defects and their effects on drilling quality expalined
in detail. It will be even more helpful if any one can tell me the effect of
different drilling parameters and their effect on drilling quality in
detail.
Warm regards,
Swati
