Is your NSK Ti-Max dental handpiece getting weak, making noise, or not spinning up to speed? The turbine inside is likely worn out. This is a generic replacement push button turbine cartridge designed specifically for NSK Ti-Max models like the X600L, X600KL, X600WL, X600SL, and similar variants. It's brand new, in its packaging, and ready to bring your high-speed handpiece back to life. Replacing the turbine is a common and cost-effective repair that can save you hundreds compared to buying a whole new handpiece. It's compatible with the push-button chuck system. Perfect for dental technicians, dentists, or clinics that do their own maintenance. Please note: This is a generic/unbranded part (MPN does not apply), but it's built to fit and function. Installation requires some skill and the proper tools – if you're not comfortable, have a professional do it. Get your favorite handpiece running smoothly and powerfully again for a fraction of the cost!
