Dont like to disagree mike but i just bought 2 of the long burrs single cut for only 16 bucks each from mc master carr.

Dont like to disagree mike but i just got some from mcmaster good quality ones to, 1 was 16 and 1 was 20.

Agree to disagree. I see a lot of smaller bits in that price range. The larger bits are more in the $30-50 range. McMaster-Carr
