Features
This model represents the pinnacle of the Mr. Meister series precision handpiece grinders and is designed to deliver professional-level performance for precision machining. The innovative design features smooth curves and a feedback circuit that enhances torque while maintaining minimal core runout. As a result, the handpiece provides stable and accurate rotation during demanding precision work.
Moreover, the controller includes two handpiece cable ports, allowing users to easily switch between two handpieces, with one handpiece included as standard. An optional additional handpiece further reduces the need for frequent bit changes, which improves workflow efficiency. The included sleeve collet also enables convenient one-touch switching between 2.35 mm and 3.0 mm tip bits, allowing users to adapt quickly to different tasks.
In addition, the standard foot controller provides infinitely variable speed control, which allows smooth and precise speed adjustments during operation. The system also supports built-in forward and reverse rotation, giving users greater flexibility when working with different materials. A convenient foot speed controller and handpiece stand are included as standard, which enhances comfort and control during extended use. As a result, this high-performance handpiece grinder becomes an ideal tool for professionals performing precision grinding, engraving, and detailed machining work.
