Using Burs

Grind a bevel on the end of the shank on all your burs.  Then they will be easier to insert into your flex-shaft handpiece when using.

When using burs, you should insert the shank all the way into the handpiece.  The chuck should hold the shank as close to the bur head as possible.  This will provide more accurate control and it is safer to operate this way.

Always use a steady speed and even pressure.  Varying the speed by pumping the foot pedal or un-even pressure while cutting will cause un-even cutting and wear out the flex-shaft prematurely.
