However, as a steady drill bit customer, I personally have stopped
purchasing bits from unknown vendors, or bits that are not made in

failures (dulling, then breaking) with drill sets made elsewhere, and
most importantly, I have found on occasion practically an entire set
will have actual measured diameters that have only a casual
relationship to what is specified.

Well said, and a sound warning. Ignore at your own risk.
