What High Speed Repairs Cost
Turbine Rebuild Starts at $129
New bearings, springs, turbine O-rings, visual inspection of your existing housing and existing chuck. Clean, lubricated and speed-tested with and without load, before it ships.
New Turbine + Rebuild $159–199
The whole turbine or cartridge replaced when the seat or housing is past rebuilding. This includes new bearings, springs, turbine O-rings and lubrication. Priced by model on your estimate.
$29 If the Head Is Past Rebuilding
Occasionally a seat or housing is worn beyond what a new cartridge can fix. You owe nothing for the repair in that case — a flat $29 covers shipping and handling, and we will 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 new turbine runs $159 to $199 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, cleaning and a full speed test under our 6-month parts and labor warranty.
What a $129 turbine rebuild actually includes
- New bearings and O-rings in your existing turbine, chuck inspected — a turbine rebuild
- Every head run to rated speed and checked for concentricity — chatter you can feel is runout we can measure
- Water spray pattern and optics verified on the same bench run, not assumed
- $129 covers the common bearing-and-seal rebuild; a full cartridge with new chuck is quoted in writing before we start
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. 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. Cleaned, rebuilt, then speed, torque and spray pattern checked on the bench, plus light output on fiber optic heads.
- Back to your operatory. UPS or FedEx, 2–3 business days on the bench, 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, 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.
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, 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?
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?
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 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.
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. 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.
