Can some one please help me with drill bit size numbering? I have
Googled, but my finds were confusing.
Some fitting require hole size in inches, some in mm, ok I can convert
those, but others are in Drill Numbers, for example a wall plug may
require Drill #10, where can I find these equivalences please?
TIA
