General Information for Bur Use:

  • It may be necessary to adjust the bur speed as shown under maximum recommended operating speeds for optimum performance.
  • Use slower speeds for harder materials.
  • Use faster speeds when using small burs.
  • Apply constant pressure and movement when in use.
  • Running burs below recommended speeds may cause chipping.
  • Do not use worn out tools and collets as they will also cause chipping.
  • Running burs too fast will cause teeth to wear prematurely.
