10. Allowable rotation speed
This chart is a general guide for a maximum speed with conventional burs.
The allowable rotation speed can be slightly different, depending on bur materials or types.
Notice
1) Make sure not to extend the maximum speed specified by a manufacturer or distributor.

2) Large burs, even being operated below maximum speed, will vibrate.
Test Bur
Speed should be reduced immediately to prevent damage to a bur, a handpiece or
operator.
3) Be sure to insert the bur shank all the way, until it touches the back of the collet chuck,
then tighten a collect chuck. If the bur is used not inserted completely, it is very
dangerous.
