Electric Handpiece Repair
Why Practices Trust Us With Their Electric Handpieces
We rebuild electric attachments from every major manufacturer — gear trains, bearings, seals and optics — then verify speed and torque against the console they run on before anything ships back.

Gearbox and Optics Checked Together
An electric attachment rarely fails in one place. We open the gearbox, the seals and the light path in the same sitting, because a tired gear set will destroy a fresh bearing inside a month. Inspection costs nothing.
You Approve the Price Before Any Repair
You get the number in writing once we know what is worn, and nothing gets repaired until you say yes to it. Send it in on a prepaid label the same day you ask — no minimum, no account needed.
No Repair Charge If It Cannot Be Saved
Some electric attachments come back past the point where a rebuild is honest. When that happens there is no repair charge at all — you just pay a small fee for return shipping and handling, and we tell you why.
Electric attachment repair starts at $239. What you pay depends on the model and what is actually worn — a bearing and single-gear rebuild sits at the lower end, a complete overhaul of all damaged gears and bearings at the higher end (transmission not included). Every quote includes parts, labor, inspection and a full performance test under our 6-month parts and labor warranty, and you see a written price before any work begins.
What “Best Price” Actually Means on an Electric Handpiece Repair
Three levels, all done in our repair facility and quoted after inspection: a basic rebuild from $239 (shaft gear or head gear plus bearings), a partial rebuild from $369 (head gear and shaft gear plus bearings), and a complete overhaul from $419 (all damaged internal gears and bearings; transmission not included). Every level includes ceramic bearings, springs, spacers and O-rings, lubrication, and a concentricity and load test, under our 6-month parts and labor warranty. Nothing is shipped to the manufacturer — the repair stays with us, which is why a full rebuild here costs less than the $550–$750 “factory overhaul” most shops resell.
Start With the Symptom
Most electric faults announce themselves the same way every time. Find what yours is doing below and you will know roughly what is wrong, and what it costs, before you ship anything. On an electric handpiece the gear train fails before the motor does — that one fact explains most of what follows.
How to Send Us Your Electric Handpiece
Five steps, and three of them are ours. The part you handle should take minutes.
Electric Repairs by Model
Air-driven turbines are on our high speed handpiece repair page, and contra angles, straight attachments and the motors behind them on our low speed handpiece and motor repair page.
| Brand | Models we service | Most common repair | From |
|---|---|---|---|
| NSK | Ti-95, Ti-85, X95, X85, Ti-Max Z95L, X-SG20L | Gear train — torque fades before speed | From $239 |
| KaVo | 25 LHA, 25 LPA, LPR, 200XDR, M05, M25 L | Bearings, then chuck | From $239 |
| A-dec / W&H | WK-93, WG-99, WA-99 LT | Coupling O-rings and gearing | From $239 |
| Midwest | E Pro, E Plus, E Mini | Gears and bearings, calibration | From $239 |
| Star | 1:5 AC | Gear train and seals | From $239 |
| Brasseler | Forza F5 | Bearings and chuck | From $239 |
Is it the motor or the attachment?
Nine times out of ten it is the attachment. Motors are simple and durable; the gear train hanging off them is doing the work and it is what wears. The quickest self-check is the one in the symptom list above — if the console still reports normal speed while the bur stalls, that is the transmission, not the motor.
You do not have to work it out. Send it and we will tell you which it is, and what each option costs, before you commit to anything.
What a rebuild actually includes
Worn gears and bearings replaced as needed, seals renewed, chuck inspected, optics checked where fitted, then the whole assembly run under load rather than free-spinning. Speed and torque are verified against the console the attachment will go back on, which is why we ask which motor you run.
Everything carries a 6-month parts and labor warranty.
NSK Electric Handpiece and Micromotor Repair
Ti-Max Z95L, X95, X85, Ti-95 and Ti-85 attachments arrive with the same complaint: torque fades before the console shows any drop in speed. That is the 1:5 gear train. Worn gears and bearings are replaced as needed, seals renewed, then speed and torque verified against the motor you run. From $239.
NLZ micromotors are a different job — the motor itself, not the attachment — and fall under our Electric Motor Overhaul from $549; see NLZ micromotor repair on the NSK page. Full model detail is on our NSK handpiece repair page.
KaVo Electric Handpiece Repair
The 25 LHA, 25 LPA, LPR, 200XDR, M05 and M25 L go the same way: bearings first, then chuck grip. Worn bearings and gears are replaced as needed, seals renewed, the chuck inspected, then speed and torque checked against the motor the attachment runs on. From $239.
Tell us which coupling it runs on — MULTIflex and INTRAmatic come apart differently. Model-by-model detail is on our KaVo handpiece repair page.
A-dec and W&H Electric Handpiece Repair
The WK-93, WG-99 and WA-99 LT are W&H-built and share a failure pattern: the coupling O-rings let go, then the gearing follows. Worn gears and bearings are replaced as needed, the coupling seals renewed, and the spray pattern checked at spec pressure before it ships. From $239.
A-dec and W&H attachments are repaired in the same facility — full model detail, including the Synea line, is on our A-dec and W&H handpiece repair page.
Star Electric Handpiece Repair
The 1:5 AC speed-increasing attachment is the Star electric we see most. The gear train goes first, then the seals behind it. Worn gears and bearings are replaced as needed, seals renewed, then speed and torque verified against the motor it runs on. From $239.
Star’s air-driven turbines — the 430 SW, SWL and the Titan line — are a different job. Those are covered on our Star handpiece repair page.
Bien-Air Electric Handpiece and Motor Repair
The EVO.15 and Nova 1:5 attachments and the MX2 and MCX motors are the Bien-Air electrics we see. Gear-train wear shows up as heat and chatter at the head; chuck grip is the other one, and it goes under electric torque. Worn gears and bearings are replaced as needed, seals renewed, then the attachment is run under load before it ships. From $239, with motor overhauls quoted separately.
Full model detail, including the CA 20:1 L implant and surgical attachment, is on our Bien-Air handpiece repair page.

Frequently Asked Questions
The questions practices ask most before sending an electric attachment or motor in. The general ones — shipping, warranty, what happens if a motor can’t be saved — are answered on our dental handpiece repair FAQ.
How much does electric handpiece repair cost?
Electric attachment repair starts at $239. The final price depends on the model and what is actually worn — a bearing and single-gear rebuild is at the lower end, a complete overhaul of all damaged gears and bearings at the higher end (transmission not included). You always get a written estimate before any work begins, and if it turns out not to be worth repairing there is no repair charge: you just pay a small fee for return shipping and handling.
Is it the motor or the attachment?
Nine times out of ten it is the attachment. Motors are simple and durable; the gear train is doing the work. The quickest self-check is whether the console still reports normal speed while the bur stalls — that pattern points at the attachment rather than the motor. You do not need to work it out, though. Send it in and we will tell you which it is before you commit to anything.
How long does an electric handpiece 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 on electric repairs?
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 attachment left the factory. On 1:5 gear trains that precision matters more than on most repairs, because an approximate part will run for a few weeks and then take the head with it.
Who has the best price on electric handpiece repair?
The best price on an electric handpiece repair is the final invoice, not the teaser rate. Ours works like this: electric attachment repair starts at $239, you get a written quote after free inspection and before any work begins, and nothing is repaired until you approve that figure. If your handpiece is not worth repairing, there is no repair charge at all — you just pay a small fee for return shipping and handling. Shipping to us is free on our prepaid label, and every electric dental handpiece repair carries a 6-month parts and labor warranty. Compare any flat-rate offer against that total and check what their warranty actually covers — see our full pricing by brand and model.
