Your questions before choosing
Is my handpiece compatible?
Check the shank diameter accepted by your handpiece and follow its manufacturer's instructions and the speed limits for this reference.
Why do several references have the same colour?
Colour does not describe every characteristic of a bit. Compare the reference, shape, dimensions and technical information before choosing.
Are the extras required?
No. You can buy only the main bit. Extras are optional and their prices are itemised in your selection.
