NSK Repair Pricing

High-Speed Handpiece Rebuilds From $129

NSK 9000, Kinetics and Z micro turbine rebuild: bearings, chuck and O-rings replaced, then speed-tested — with extra care on the micro head, where clearances are tightest.

Low-Speed Attachments From $145

Contra angles and attachments stripped to the gear train and rebuilt, then run under load, because on a speed increaser torque fades long before RPM does.

Electric Handpieces From $229

Ti-Max and X-series electrics: gears and bearings replaced as a set rather than one at a time, seals renewed, then torque verified against your console spec.

Every quote includes parts, labor, cleaning, and a full performance test, and every repair carries our full 6-month parts and labor warranty. Prices below cover the most common NSK repairs; see our complete pricing menu, broken out by repair type and brand, on our Services page. Whether you need high-speed handpiece repair, low-speed handpiece repair, or electric handpiece repair, our NSK handpiece repair pricing stays flat and transparent, so you always know the cost of dental handpiece repair before you ship a unit to our bench.

Common NSK Handpiece Repair Issues We Fix

NSK is the brand where the transmission fails before anything else. On most makes the bearings go first; on NSK it is the gear train. The 1:5 increasing transmissions are built to tolerances most manufacturers do not attempt, and that same precision is what makes them unforgiving once wear starts. It shows up as torque, not speed — the console still reads normal while the bur stalls in dense dentin. If it feels slower than the display says it is, that is the transmission talking.

Torque Loss Before Speed Loss

The Ti-Max and X-series attachments run a 1:5 increasing gear train, and as those gears and bearings wear, torque drops well before RPM does. Your console still reports normal speed while the bur stalls in dense dentin. That gap between what the display says and what your hand feels is the classic early NSK warning.

Bearing Noise in a Quiet Head

A healthy NSK head is close to silent, so any new whine or buzz is worth acting on the same week. Tolerances are tight enough that debris from one failing bearing scores the surrounding surfaces quickly, and a straightforward bearing job becomes a full rebuild if it waits.

Mini-Head Wear on the 85 Series

The X85 and Ti-85 mini heads run smaller bearings in a tighter envelope than their standard-head counterparts. They buy you better posterior access, but they are less forgiving of debris and over-lubrication, and they show wear sooner. We service them to the smaller spec rather than treating them like a standard head.

Chuck Slipping Under Load

Worn collets let the bur creep down or spin in the chuck part-way through a crown prep. On the push-button autochuck heads this is a chuck assembly replacement rather than a new handpiece, and we verify grip with a pull test before it goes back in the box.

LED and Fiber Optic Failure

The Z95L and the other optic-equipped models lose illumination as the glass rod clouds or the emitter degrades. Because it fades gradually, most practices compensate for months without noticing. We replace the bundle or emitter and check output against a known-good unit.

Blocked Spray Ports

NSK routes its four-port spray through finer internal passages than larger heads, so scale and debris block them sooner. A misdirected or dead port means heat at the prep. We flush the water and air lines, clear the ports, replace the O-rings and pressure-test the spray pattern before it ships.

How to Send Us Your NSK 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. On an NSK attachment, tell us which motor and console it runs on — that is what we set the finished torque and speed against.
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 — including the four-port spray, which blocks sooner on NSK than on larger heads.
Back to your operatory. UPS or FedEx, roughly 7 business days from arrival, under the 6-month parts and labor warranty.

NSK Models We Service

Below are the NSK models we service most often. NSK builds to tight tolerances, which is what makes these handpieces so good and also what makes approximate repair work show up immediately, so every unit is rebuilt to spec and tested before it ships. If yours is not listed, call us at (720) 998-2820 — this covers our most common work, not everything we repair.

We rebuild every major handpiece brand on the same terms and the same bench. If your operatory runs more than one, see our KaVo handpiece repair, Midwest handpiece repair, Star handpiece repair and Adec and W&H handpiece repair pages, or browse every brand we repair.

NSK Standard-Head Electric Attachments

NSK Ti-95 and X95 — the standard-head 1:5 speed increasing attachments, rated to 200,000 rpm. Gear wear and bearing wear are the two jobs we do most on these, and we replace them as a set rather than chasing one at a time.

NSK Ti-Max Z95L — the current-generation 1:5 contra angle, with ceramic bearings, four-port spray and glass rod optics. We rebuild the head, renew the seals, and verify speed and torque against spec before it ships back.

NSK Mini-Head Electric Attachments

NSK Ti-85 and X85 — the miniature-head versions of the same 1:5 gear train, built for access to posterior preparations. The smaller head means smaller bearings and less room for error, so these reach our bench more often and need to be serviced to their own tolerances rather than the standard-head spec. We rebuild the gear train, replace the bearings and chuck, then run them under load to confirm the torque actually came back.

NSK Surgical and Air-Driven Handpieces

NSK Ti-Max X-SG20L — the 20:1 reduction surgical contra angle used for implant placement and bone work. Reduction gearing carries far more torque than a speed-increasing head, so the gear train and bearings wear differently and have to be rebuilt to the reduction spec. We renew the gears, bearings and seals, then test torque at surgical speeds before it ships.

NSK Ti-Max Z micro — the micro-head air turbine, built for restricted access and paediatric work. The smaller head leaves very little margin around the turbine cartridge, so debris and over-lubrication show up faster here than on a standard head.

NSK 9000 and NSK Kinetics — the air turbine workhorses. These get a full turbine overhaul: new bearings, new chuck, fresh O-rings, a complete clean and a speed test before they go back in the box. The turbine cartridge is the wear item, and on a well-maintained NSK turbine a rebuild returns it to original cutting performance rather than just getting it running again.

Frequently Asked Questions

NSK builds to tolerances most brands do not attempt, and that is exactly why the same handful of issues come up again and again: worn 1:5 gear trains, bearings that went quiet-to-noisy in a week, clouded optics and blocked spray ports. Below are the questions practices ask us most before sending an NSK handpiece in.

Do you repair NSK electric attachments and air turbines?

Yes. We service the whole NSK range — the Ti-Max and X-series electric attachments including the Ti-95, Ti-85, X95, X85 and Z95L, the X-SG20L 20:1 surgical contra angle, and the air-driven Z micro, NSK 9000 and Kinetics turbines. Every repair ships back with our full 6-month parts and labor warranty and a free diagnostic estimate up front. We send you a free prepaid USPS shipping label to get it to our office, with no minimum order value.

What parts do you use on NSK repairs?

We use quality replacement parts matched to your specific model rather than close-enough substitutes, and on NSK that distinction matters more than on most brands. The 1:5 gear trains and the mini-head bearings run to tolerances where an approximate part will run for a few weeks and then take the head with it. If you want to know exactly what is going into your handpiece, call us at (720) 998-2820 and we will tell you before we order it.

What is covered under the warranty?

Every NSK repair carries a full 6-month parts and labor warranty, and you get a free diagnostic estimate before any work begins — you will never receive an invoice you did not approve first. If a handpiece turns out not to be worth repairing, there is no repair charge at all: a flat $29 covers shipping and handling and it goes back to you.

How long does an NSK repair take?

About 7 business days from the day it reaches our bench, and 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.
