Colt 7mm HSS pen Drill
As we were almost finishing the catalogue in 2009 we were introduced to these drill bits and have tried them.
They are truly staggering. An amazingly fast cut with no break-out (even on made acrylic or Dymondwood blanks) leaving a perfectly clean bore.
Colt have changed the design of the 7mm pen blank drill, they are now 109mm (4 1/4”) long overall, 83mm (3 1/4”) drilling length.
We found they work best at a higher speed.
Take a look at the excellent two and a half minute youtube video. It shows it all and is very well presented.
