What High Speed Repairs Cost
High Speed Rebuild
from $129New bearings, springs and turbine O-rings. Your existing housing and chuck are inspected, then the head is lubricated and speed-tested with and without load before it ships. 6-month parts & labor warranty.
High Speed Overhaul
from $159The whole turbine or cartridge replaced, with a new chuck, when the turbine and chuck are past rebuilding. Includes new bearings, springs, turbine O-rings and lubrication. Priced by model on your estimate.
If the Head Is Past Rebuilding
No repair chargeOccasionally the head itself is too worn for a new turbine to fix, and on a high speed that usually means it can't be repaired. You owe nothing for the repair — you just pay a small fee for return shipping and handling, and we tell you whether replacement or a different model makes more sense.
High speed rebuilds start at $129 and hold at that price across brands. A high speed overhaul with a new turbine runs from $159 depending on the model. Which one you need comes down to whether the housing is still true, and you see a written price before any work begins. Every quote includes parts, labor, inspection and a full speed test under our 6-month parts and labor warranty.
What a $129 high speed rebuild actually includes
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 wears the turbine and chuck until it needs an overhaul.
How to Send Us Your High Speed Handpiece
Five steps, and three of them are ours. The part you handle should take minutes.
- Ask for a label. Start on our Book My Repair page and 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. Inspected, rebuilt, then speed, torque and spray pattern checked on the bench, plus light output on fiber optic heads.
- Back to your operatory. UPS, FedEx or USPS Ground, 2–3 business days on the bench, under the 6-month parts and labor warranty.

Rebuild or overhaul?
A rebuild reuses your turbine housing and replaces what wears inside it — bearings, springs, head O-rings and washers. 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.
An overhaul puts in a new turbine — the whole cartridge, with a new chuck. That’s the repair once the turbine and chuck are past rebuilding. 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 we repair. See our electric handpiece repair page, or the brand pages for KaVo, Midwest, Star, NSK, Adec and W&H, Brasseler, Lares, Bien-Air, Beyes and the Impact Air 45. Surgical 45-degree handpieces have their own endo and surgical handpiece repair page, and the sonic scalers that thread onto the same coupling are covered on our ultrasonic and sonic scaler repair page. Full rates are on our repair pricing page.
Frequently Asked Questions
The questions practices ask most before sending a high speed handpiece in. For everything else — shipping, warranty, what happens if a head can’t be saved — see our dental handpiece repair FAQ.
How much does high speed handpiece repair cost?
High speed rebuilds start at $129 and stay there whatever the brand. A high speed overhaul with a new turbine runs from $159 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: you just pay a small fee for return 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 the turbine and chuck are past rebuilding. You do not have to decide — we inspect it free and tell you which it needs.
How long does a high speed repair take?
2–3 business days on the bench. Add transit each way — typically a couple of days in each direction on the prepaid label, though that part is the carrier’s clock, not ours. 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, FedEx or USPS Ground.
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.
What does a high speed handpiece repair service cost?
High speed rebuilds start at $129, and the price moves with what the head actually needs. A worn bearing-and-seal set sits at the bottom of the range. An overhaul — a complete turbine cartridge with a new chuck — sits at the top. Optics and couplers are quoted on their own when they are worn, so you are never paying cartridge money for a bearing problem. The exact figure is in writing after free inspection — see pricing by brand and model for where your handpiece falls.
