Makita 9564CV 4-1/2-Inch SJS High-Power Angle Grinder | 12A Variable Speed

Overview

The Makita 9564CV 4-1/2-Inch SJS High-Power Angle Grinder blends compact ergonomics with serious material-removal capability. Driven by a high-output motor in the 12 to 13 amp class and a five-stage variable speed control (2,800 to 10,500 RPM), this tool adapts to grinding, shaping, and finishing tasks across metalworking projects.

Protection and longevity by design

Durability features are built to endure tough shop environments. The Super Joint System (SJS) helps prevent gear damage and reduces kickback when a disc binds, while an electronic limiter guards the motor from overload. A larger carbon brush arrangement supports longer service life, and labyrinth seals paired with zigzag varnish coatings shield the armature and field from dust and heat.

Ease of use and setup

• Five-stage speed control lets you match RPM to the application and disc type.
• Soft start minimizes abrupt starts for smoother operation and reduced wear on gears.
• Tool-less wheel guard adjustment enables quick clamping and wheel changes.

Performance you can depend on

In real-world use, you’ll appreciate consistent power delivery at higher RPM and automatic speed correction under load. The grinder’s robust motor and clutch system help maintain control during heavy material removal, while the compact frame makes it easier to reach tight spaces on jobsites.

Design details that matter

• Labyrinth construction seals the motor and bearings from dust and debris.
• Protective zigzag varnish seals the armature and field, helping manage heat in extended sessions.
• Barrel-style grip and balanced weight contribute to comfortable operation during longer tasks.
