Makita 4-1/2" SJS Paddle Switch Angle Grinder

When I first got my hands on the Makita 4-1/2" SJS Paddle Switch Angle Grinder (model 9564P), I was immediately impressed by its robust design and the promise of high performance. As someone who frequently undertakes demanding grinding and cutting tasks, I was eager to see how this tool would hold up under pressure.

Build Quality and Design

The Makita angle grinder exudes a sense of sturdiness right out of the box. Weighing in at 5.1 lbs., it strikes a good balance between being lightweight enough for prolonged use and heavy enough to feel substantial in hand. The labyrinth construction is a standout feature, protecting the internal components from dust and debris, which is a critical aspect for longevity, especially in dusty environments.

The paddle switch design, while different from the traditional trigger switch, offers a unique blend of comfort and safety. The lack of a lock-on feature might be a minor inconvenience for some, but it significantly reduces the risk of accidental startups, which is a crucial safety measure.

Performance

Powered by a 10 AMP motor, the Makita grinder delivers an impressive 11,900 RPM, making it more than capable of handling a variety of tasks. Whether I was cutting through porcelain tiles with a diamond blade or grinding down rusted bolts on an old Jeep, the grinder performed consistently well. The power output is smooth and reliable, never once stalling even during the most demanding tasks.

One of the standout features is the SJS™ (Super Joint System) technology, which is designed to prevent motor and gear damage by allowing the drive shaft to slip if the wheel is forced to a stop. This not only protects the internal components but also provides a smoother operation by reducing the shock on the user.

Usability

The tool-less wheel guard adjustment is a practical feature that enhances the usability of the grinder. It allows for quick and easy adjustments without the need for additional tools, making the workflow more efficient. However, it's worth noting that the grinder does not come with any blades or grinding wheels, so you'll need to purchase those separately.

The paddle switch, while comfortable, does take some getting used to. Unlike traditional switches, the paddle switch requires continuous pressure to operate, which can be a bit cumbersome for extended use. However, this design significantly enhances safety by ensuring the tool stops immediately when the pressure is released.

Durability

Durability is where the Makita grinder truly shines. After using it heavily for almost two years, it has shown no signs of giving out. The motor and internal components are well-protected, thanks to the labyrinth construction and SJS™ technology. Even the power cord, which can often be a weak point in many tools, has held up well under continuous use.

Value for Money

Priced under $100, the Makita grinder offers exceptional value for money. It's rare to find a grinder in this price range that delivers such consistent performance and durability. While the initial investment might seem steep, the long-term reliability and performance make it a worthwhile purchase.

Areas for Improvement

No tool is without its flaws, and the Makita grinder is no exception. The paddle switch, while a great safety feature, can be challenging to manipulate, especially for those used to a traditional trigger switch. Additionally, the grinder does not come with any blades or grinding wheels, which means additional purchases are necessary to get started.

Another minor issue I encountered was with the power cord. During one particularly demanding task, the cord came undone from the wiring after only a few hours of use. While this was easily fixed with some electrical tape, it's something to be aware of if you plan on using the grinder for extended periods.

Conclusion

In conclusion, the Makita 4-1/2" SJS Paddle Switch Angle Grinder is a robust, high-performing tool that is well worth the investment. Its powerful 10 AMP motor, combined with the innovative SJS™ technology and labyrinth construction, ensures reliable performance and durability. While the paddle switch design may take some getting used to, it significantly enhances safety during operation.

For anyone in need of a reliable and powerful angle grinder for demanding tasks, I highly recommend the Makita 9564P. Its blend of performance, durability, and value for money makes it a standout choice in the market. Whether you're a professional tradesperson or a DIY enthusiast, this grinder is sure to meet your needs and exceed your expectations.
