I put an image of a drill bit on my website to try to show this problem.

The RED areas show where, IMO, metal is missing from the back side of
the land area.
I'd be interested to hear from others who have had similar experiences

Not a bad drill bit.. a bad drill bit sharpener. That form is common in roll
forged twist drills. Normally found in larger sizes though.
