The fivestage variable speed dial (4,000 9,000 RPM) allows the user to match the RPM to the application. The electronic limiter stops the motor and reduces accidental motor overload and burnout, and the electronic speed control maintains consistent speed under load. Labyrinth construction protects the motor with a complex set of channels, prohibiting dust and contamination. In addition, the protective zigzag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation. The 9566CV is engineered with SJS, an innovation from Makita that protects the gears by automatically disengaging the motor should the grinding wheel accidentally catch or bind.Comfort and ErgonomicsThe 9566CV is built with comfort and ergonomic features for extended use. The grinder weighs just 5.3 pounds with a lockon switch for easy operation. In addition, the side handle can be easily installed on either side of the tool, and the toolless wheel guard adjustment provides easy clamping.Variable Speed for Stone WorkThe 9566CV is a versatile and powerful grinder with variable speed, allowing the user to set the RPM to the material. The variable speed control feature makes the 9566CV ideal for stone work, including polishing, grinding and cutting. The 9566CV is just another example of Makitas commitment to innovative technology and bestinclass engineering.About Makitas Super Joint System (SJS)Super Joint System (SJS) is an innovation from Makita engineering where the motor armature and spiral bevel gear are linked by a coil spring. If the grinding wheel catches or binds, the coil spring relaxes and disengages the gears from the motor. As the grinding wheel stops, the gears and motor are protected.
