Makita 9566CV 6” SJS™ High-Performance Variable Speed Angle Grinder

Command maximum cutting depth and relentless heavy-duty power. Built with a robust 13 AMP motor, a tool-free 6" guard, and Makita’s signature SJS™ mechanical safety clutch.

When slicing through thick quartz blocks, deep profiling dense granite slabs, or managing high-torque metal fabrication, standard compact grinders simply run out of capacity. The Makita 9566CV 6" Variable Speed Angle Grinder is engineered to deliver high-performance cutting, grinding, and polishing with an extended reach. Powered by a heavy-duty 13 AMP motor, this machine utilizes Makita's patented SJS™ (Super Joint System) mechanical clutch, which allows the drive shaft to slip instantly if your 6-inch wheel or blade encounters a severe bind—completely protecting the internal gears and motor from catastrophic burnout. With advanced electronic speed stabilization and a tool-free guard system, it is the ultimate workhorse for shops looking to upscale their heavy-duty production efficiency.

Why High-Volume Stone Shops and Fab Crews Run the 9566CV:

  • Expanded 6-Inch Cutting Capacity: Designed to run larger 6" wheels, offering a significantly deeper cutting depth and wider grinding footprint than traditional 4-1/2" models.

  • Patented SJS™ Gear & Motor Protection: The innovative Super Joint System automatically disengages the mechanical drive if the cutting wheel catches or binds, saving your tool from motor failure and preventing severe kickback.

  • Custom-Calibrated Variable Speed Dial: Seamlessly tune your RPM from 4,000 to 9,000 RPM using the integrated control wheel to match the ideal heat tolerances of natural stone, quartz, or hardened metals.

  • Intelligent Electronic Speed Control: An advanced internal monitor constantly stabilizes power delivery, forcing the motor to maintain uniform, skip-free speed even under intensive structural downward pressure.

  • Tool-Free Adjustable Guard System: Outfitted with an engineered, rapid-adjustment wheel guard that changes position in seconds without requiring wrenches, keeping your fabricators safe and moving fast.

  • Ergonomic Slim-Body Geometry: Features an ultra-slim body barrel paired with a multi-position side handle, dramatically reducing operator fatigue during prolonged job-site or shop use.
