High Speed Handpiece Repair
Why Practices Trust Us With Their Turbines
We rebuild air-driven high speed handpieces from every major manufacturer — bearings, chuck, O-rings and optics — then speed-test every head on the bench before it ships back.
- Torque verified under load, not free-spinning
- Full 6-month parts and labor warranty
- Free prepaid shipping label with every repair
- Free diagnostic estimate before any work begins
What High Speed Repairs Cost
Turbine Rebuild Starts at $129
New bearings, chuck and O-rings in your existing housing, cleaned and speed-tested before it ships.
New Turbine $159–199
The whole cartridge replaced when the seat or housing is past rebuilding. Priced by model at the estimate.
Nothing owed if unrepairable
No repair charge at all. A flat $29 covers shipping and handling and it comes back to you.
Start With the Symptom
On an air turbine the bearings fail before anything else, and they announce it early. A high speed handpiece is quiet and smooth when healthy, so the first change you notice — a rising pitch, a buzz through the grip, a bur that wanders — is almost always the bearings. Act on it then and it is a bearing job. Leave it and the vibration works on the chuck seat and the housing until it becomes a full rebuild.
How to Send Us Your High Speed Handpiece
Five steps, and four of them are ours. The part you handle should take minutes.
- Ask for a label. Call (720) 998-2820 or use the estimate form. A prepaid USPS label reaches you the same business day, no minimum order, nothing to pay up front.
- Box it up. Bubble wrap, sturdy carton, and a note with your practice name and the symptom. Tell us whether the chuck is push-button or lever, and on a Star whether it is SWL or Lube Free — that changes what we pull first.
- We look, then we quote. Inspection is free, and nothing is opened past that point until you have a written price and have approved it.
- We rebuild and prove it. Cleaned, rebuilt, then speed, torque and spray pattern checked on the bench, plus light output on fibre optic heads.
- Back to your operatory. UPS or FedEx, roughly 7 business days from arrival, under the 6-month parts and labor warranty.

Rebuild or new turbine?
A rebuild reuses your turbine housing and replaces what wears inside it — bearings, chuck, O-rings. It is the right call while the housing is still true, which is most of the time if the handpiece came in when it first got noisy.
A new turbine replaces the whole cartridge. That becomes the better value once vibration has worked on the chuck seat, because a fresh bearing set in a damaged seat will not hold. We make that call at the estimate stage and tell you which one you are paying for before anything proceeds.
Lubricated and lube-free are not interchangeable
Star runs both: the 430 SWL is lubricated, the 430 Lube Free uses sealed ceramic bearings that must never be oiled. They look near enough identical on a tray. Oil a lube-free head once and the bearings are compromised.
If you are not certain which you have, say so when you send it and we will identify it before we touch it. It is the single most common way a good Star head gets shortened, and it is entirely avoidable.
We repair every major brand
High speed turbines are one part of what crosses the bench. See our electric handpiece repair page, or the brand pages for KaVo, Midwest, Star, NSK and Adec and W&H. Full rates are on our pricing by brand and model page.
Frequently Asked Questions
The questions practices ask most before sending a high speed handpiece in.
How much does high speed handpiece repair cost?
Turbine rebuilds start at $129 and stay there whatever the brand. A new turbine runs $159 to $199 depending on the model, and is quoted once we have seen the housing. You always get a written price before any work begins, and if a handpiece turns out not to be worth repairing there is no repair charge: a flat $29 covers shipping and handling.
Should I rebuild the turbine or replace it?
Rebuild while the housing is still true, which is most of the time if it came in when it first got noisy. Replace once vibration has worked on the chuck seat, because fresh bearings in a damaged seat will not hold and you will be sending it back. You do not have to decide — we inspect it free and tell you which it needs.
How long does a high speed repair take?
About 7 business days from the day it reaches our bench. We will tell you at the estimate stage if a part needs sourcing and that timeline is going to move. Getting it to us is free on our prepaid USPS label; the return trip goes out via UPS or FedEx.
What parts do you use?
Quality replacement parts matched to your specific model rather than close-enough substitutes, and we rebuild to specification so fit, torque, light output and spray pattern match how the handpiece left the factory. On turbines the bearing spec matters more than anything — an approximate bearing runs for a few weeks and then takes the head with it.
