Enlarging existing bridge pin holes

[William R. Monroe]

Hi Mark,

Any idea how slow the RPM's could get with that speed control?  As I said,
the Dremel I'm thinking of using only goes down to 5000 RPM's.  I'm not
familiar with the "Industrial" Dremel.  How does that differ from the
"Consumer" level (XRP Variable Speed unit)?

Respectfully,
William R. Monroe
