This Makita 9564PC is a beast of an angle grinder, built for pros and serious DIYers. It's powered by a hefty 13.0 AMP motor that delivers 10,500 RPM (with a max free speed of 11,500 RPM) to power through cutting, grinding, and polishing jobs. The 4-1/2 inch wheel size is super versatile, and it has a 5/8-inch spindle. The paddle switch is easy to use and includes a lock-on feature for continuous operation. Makita's SJS (Super Joint System) technology is a major plus – it's a mechanical clutch that protects the motor and gears if the wheel suddenly jams. It also has constant speed control to maintain power under load, a soft start for smoother startups, and an electronic current limiter to prevent motor burnout. It measures about 12-1/8 inches long. This is a reliable, feature-packed grinder designed for demanding job site use. If you need raw power and durability for metalwork, masonry, or heavy-duty grinding, this Makita is a top-tier choice.
