High Precision Brushless Dental Micro Polisher With Foot Pedal Control

The QZ-60 brushless polishing unit is a high-performance micromotor developed specifically for professional dental laboratory processing work. The full set includes a digital controller, Q9 brushless handpiece, foot pedal, power cord and installation wrenches. It is widely used for trimming, grinding and polishing zirconia, lithium disilicate ceramic, PFM porcelain, metal frameworks and acrylic denture bases.

The main controller adopts digital LED speed display, with precise adjustable speed from 1000 RPM to 50000 RPM. It supports dual input voltage of AC110V and AC220V, which fits global market requirements. The whole main unit weighs only 2.25kg with compact dimensions of 205*201*80mm, saving valuable bench space in crowded dental labs. The maximum output current reaches 8A with peak power up to 200W, delivering stable continuous torque without power drop during heavy grinding work.

Matched with the original Q9 brushless handpiece, this machine achieves ultra-low concentricity within 0.02mm. The handpiece is built with imported long-life bearings and a brushless motor, which eliminates carbon dust and reduces maintenance frequency. It provides strong torque up to 20Ncm even at low rotating speeds. The collet supports 2.35mm standard shank burs, which is the universal size for all dental lab grinding tools. The handpiece weighs only 245g, so technicians can operate for long hours without hand fatigue.
