Makita 9564CV 4-1/2-Inch SJS High-Power Angle Grinder — 13A Variable Speed, Mechanical Clutch

Compact power for metal grinding and finishing

Meet the Makita 9564CV 4-1/2-Inch SJS High-Power Angle Grinder, a compact tool built to handle heavy grinding and polishing tasks with confidence. Its improved 12-amp motor delivers robust output, while a five-stage variable speed dial (2,800 to 10,500 RPM) lets you tailor the pace to the material and technique you’re using. This balance of power and control helps you move from aggressive material removal to finer finishing with consistency.

Protective technology that supports long-term durability

Designed for ongoing use, the tool features several protective systems. The SJS (Super Joint System) mechanical clutch protects gears by allowing the drive shaft to slip if the wheel binds, helping reduce wear and kickback. An electronic limiter prevents motor overload, while labyrinth construction seals the motor and bearings from dust and debris. A zigzag varnish coating on the armature and field further aids heat management and contaminant resistance, supporting steadier performance under demanding conditions.

Ease of use for busy workflows

Everyday usability is at the forefront with practical design choices. Tool-less wheel guard adjustment enables quick clamping and fast wheel changes, while soft-start and constant-speed control work together to provide smooth starts and steady performance under load. This grinder accepts standard 4-1/2" wheels, helping you stay productive across a range of tasks, from rough material removal to refined finishing.
