So, I want to shorten the shaft of my bur, but what is the best
way to do this? I would appreciate any help in this matter.
Here’s how I’d do it.
Put the bur in a pin vise.
Mark the spot the cut will be made.
Put a new cutoff disc in your flexshaft.
Cut the bur off at the mark. When getting close to finishing the cut
hold the bur end with a needle nose pliers so it won’t go flying off
to never never land.
Clean up any burrs left on the cut end of the bur.
