Makita 9564CV Angle Grinder Review Powerful Variable Speed Tool with Gear Protection

Description

Favorable Aspects of the Makita 9564CV 4-1/2-Inch SJS High-Power Angle Grinder

After testing the Makita 9564CV 4-1/2-Inch SJS High-Power Angle Grinder, I can confidently say that its 12 AMP motor with variable speed control is a standout feature. The ability to adjust the speed from 2,800 to 10,500 RPM lets me tailor the tool’s power to different tasks, whether grinding stone, polishing metal, or sanding. This versatility is impressive, especially for a grinder that weighs just about 4 pounds. The Super Joint System (SJS) mechanical clutch is another highlight; it saved me from a few potential gear damages when the wheel caught unexpectedly. This safety feature really adds peace of mind during heavy-duty work.

The ergonomic design deserves attention too. The barrel grip handle fits comfortably in my hand, and the side handle can be mounted on either side, making it easy for both right- and left-handed users to operate. I appreciate the lock-on switch, which allows for continuous operation without constantly holding the trigger. The tool-less wheel guard adjustment also makes switching tasks quick and hassle-free, something I found quite convenient during a job that required frequent wheel changes.

• Powerful 12 AMP motor with variable speed control
• Innovative SJS mechanical clutch for gear protection
• Lightweight and ergonomic design for comfort
• Tool-less wheel guard adjustment for easy use

Drawbacks to Keep in Mind

No tool is perfect, and this grinder has a few quirks worth mentioning. First, the cord length is only about 10 feet, which can feel a bit restrictive on larger job sites without an extension cord. I noticed that the grinder can get quite warm during prolonged use despite the labyrinth construction designed to protect the motor. While the heat didn’t affect performance, it might become uncomfortable for users during extended sessions.

The vibration level, rated at about 5.0 m/s², is noticeable but manageable. For long grinding or polishing jobs, I found my hand getting a bit fatigued, even with the comfortable grip. Another downside is the absence of a lock-off switch, which some might prefer for added safety when the tool is not in use. Also, the package doesn’t include a battery or charger, but since this is an electric-powered corded tool, that’s expected.

• Limited cord length (10 feet)
• Heat build-up during extended use
• Noticeable vibration causing hand fatigue
• No lock-off switch for added safety

Performance and Versatility in Real-World Use

This angle grinder shines in its variable speed performance. The five-stage speed dial is intuitive and precise, letting me slow down for delicate polishing jobs or crank it up for heavy grinding. The electronic speed control keeps the RPM steady even when the tool is under load, which means no frustrating speed drops during tough tasks.

Testing it on different materials like stone, metal, and even some fiberglass, the tool performed consistently well. The soft start feature is subtle but effective, preventing that sudden jerk when powering on, which can sometimes throw off your balance or scratch the workpiece. The labyrinth construction and zig-zag varnish on the motor provide an extra layer of dust protection, which I appreciated after working in particularly dusty environments.

The included accessories like the 4-1/2-inch grinding wheel, wheel guard, side handle, inner flange, lock nut, and wrench cover all the basics, so no need to buy extras right away. Having the ability to quickly adjust the wheel guard without tools is a time-saver and ensures safety.

Comfort and Ergonomics for Extended Use

The grinder’s 4-pound weight makes it feel surprisingly light in hand, especially compared to other models in this power class. The barrel grip design promotes a natural wrist position, reducing fatigue during long grinding sessions. I found switching the side handle from left to right quite straightforward, which helped when working in tight spaces or awkward angles.

Despite the vibration being noticeable, the handle’s design and rubberized grip helped absorb some of it. The lock-on switch was a hit during repetitive tasks; I could keep grinding without constantly squeezing the trigger. However, I could see how some users might want a lock-off feature to avoid accidental starts, especially in busy work environments.

Product Comparisons with Competing Brands

Comparing this grinder with popular competitors like the DeWalt DWE402 or Bosch GWS13-50VSP reveals some interesting differences. The Makita 9564CV’s SJS clutch system stands out as a superior safety feature that most competing models lack, providing better gear protection and reducing repair needs. Additionally, its variable speed range is broader than many others, offering more control for fine-tuning performance.

However, some rival grinders come with longer cords or cordless options, which may appeal to users valuing mobility. The DeWalt grinder, for instance, feels slightly heavier but has a better vibration control system. Bosch models often boast quieter operation but don’t match the Makita’s motor protection tech.

In terms of build quality, Makita’s labyrinth motor sealing and zig-zag varnish are notable durability perks that few competitors offer. If your work demands a grinder that can hold up in dusty or harsh conditions, this model edges ahead. On the downside, competitors sometimes include additional accessories or offer better ergonomic features like softer grips or vibration damping.

Value for Money and Price Performance

Considering the features packed into this compact grinder, the price to quality ratio makes it a smart buy for professionals and serious DIYers alike. The durability enhancements such as the mechanical clutch system and motor protection justify the investment, especially if you plan to use the tool regularly on tough jobs.

While the initial cost might be higher than some basic grinders, the potential savings on maintenance and replacement parts balance that out. Its versatile speed control and ergonomic design add to the overall value, making the grinder suitable for a variety of applications—from stone grinding to metal polishing.

Features That Matter: What’s Inside the Box

The package includes everything you need to get started: a 4-1/2-inch grinding wheel, side handle, wheel guard, inner flange, lock nut, and wrench. Having these essentials bundled means no extra trips to the hardware store, and the tool-less guard adjustment is a standout convenience feature that lets you reposition the guard in seconds.

I also appreciated the soft start and electronic limiter features, which help extend the life of the tool and protect the motor from overload. These smart engineering touches make a difference in everyday use, especially on demanding projects.

Considerations Before You Buy

If you’re after a grinder that balances power, versatility, and durability, this one fits the bill well. However, keep in mind the moderate vibration and the shorter cord length if you expect to work on larger sites. The absence of a lock-off switch might be a dealbreaker for some, depending on safety preferences.

The grinder’s weight and ergonomic features make it comfortable enough for extended use, but those sensitive to vibration should consider additional anti-vibration gloves or padding. Overall, the tool excels in motor protection and variable speed control, which are crucial for precision and longevity.
