A handpiece is the part that fails first, because it is the part that is held, dropped and run hot. Labs that cannot buy a replacement handpiece on its own end up buying a second complete micromotor and shelving a working control box.
Problems it removes
- A seized handpiece takes a whole bench out of service even though the motor and control box are fine.
- Speed ratings quoted as 35K or 45K are not interchangeable between every control box.
- E-type couplings and straight connectors vary, so the wrong handpiece will not mount.
Who buys it
- Laboratories replacing worn handpieces
- Service technicians maintaining lab equipment
- Distributors carrying spares for installed micromotors
Where This Range Is Strong
- Handpieces listed individually by model number, not only as part of a motor set.
- 35K and 45K options for the same families so the replacement matches the control box.
- E-type motors and straight connectors available alongside the handpieces themselves.

What does 35K or 45K mean on a handpiece?
It is the maximum speed in revolutions per minute the handpiece is rated for, so 35K is 35,000 rpm and 45K is 45,000 rpm. The handpiece must be matched to a control box able to drive it.
Will a Marathon handpiece fit my control box?
It fits control boxes built to the same coupling and speed standard. Send us a photo of your motor and coupling on WhatsApp and we will tell you which of the handpieces on this page matches.
Do you supply the YouDent equivalents?
Yes. YouDent handpieces SDE-H37L1, SDE-H35SP1 and 102L are catalogued alongside the Marathon and Strong models in the same speed classes.
