Ryobi 18V ONE+ 4-1/2" Angle Grinder

My introduction to the Ryobi 18V ONE+ 4-1/2" Angle Grinder began with a quest for cordless convenience in my workshop. This grinder, bearing the model number PCL445B, boasts a range of features that promise to deliver power and versatility. However, as with any tool, its true value can only be gauged through hands-on experience.

Design and Build Quality

Right out of the box, the Ryobi grinder feels solid and well-constructed. It features an ergonomic design that’s immediately comfortable to handle. The die-cast metal gear case adds to its durability, and the onboard wrench storage is a thoughtful addition, ensuring you won't misplace the tool needed for accessory changes. The 3-position side handle is another highlight, allowing for greater control and flexibility during use. This is especially useful for someone like me who frequently switches between different angles and positions while working on various projects.

Performance and Power

The grinder is powered by a robust motor capable of reaching 9,000 RPM, which is quite impressive for a cordless unit. I tested it on a range of materials, including concrete, metal, and even some thick steel bars. While it performed admirably on most tasks, I did notice a slight drop in performance with more demanding materials. The cordless convenience is a significant advantage, though, especially when working in tight or outdoor spaces where extension cords can become a hassle.

One of the critical aspects of any cordless tool is battery life. The Ryobi grinder can be quite power-hungry, especially when tasked with heavy-duty grinding. Using a 4Ah battery, I found it drained to half after about five minutes of continuous grinding on concrete. For extended tasks, having multiple batteries on hand is indispensable. This is somewhat mitigated by the fast charger included in some bundles, which can quickly get you back to work.

Usability and Safety

The tool-free adjustable guard is a feature I came to appreciate for its simplicity and ease of use. Adjusting the guard to suit different tasks is quick and intuitive, contributing to both safety and efficiency. Another thoughtful design element is the spindle lock, which facilitates rapid accessory changes. However, it’s worth noting that the grinder requires the newer 18V ONE+ batteries with extra connectors, a point that wasn't clearly communicated on the packaging. This could be frustrating for users with older Ryobi batteries, as I discovered when my older batteries failed to power the tool effectively.

The grinder's switch design is straightforward, but I did miss a lock-on feature for continuous operation. For prolonged grinding tasks, having to keep the switch pressed can be a minor inconvenience. On the safety front, the grinder has built-in features like the adjustable guard and the three-position handle that enhance user control and reduce the risk of accidents.

Versatility

During my testing, I used the grinder for a variety of tasks, from sharpening lawn mower blades to cutting metal pipes. The included grinding wheel worked well for most applications, but for specific tasks like cutting metal, additional accessories were necessary. Unfortunately, these accessories aren't included and must be purchased separately. This could be an inconvenience for users looking for an all-in-one solution straight out of the box.

The tool's versatility shines when considering the different positions you can adjust the handle to, allowing for optimal control whether you're cutting horizontally or vertically. The grinder's compact size and cordless nature make it easy to maneuver in tight spaces, further enhancing its versatility.

Durability and Maintenance

The Ryobi grinder's build quality suggests it can withstand the rigors of regular use. The die-cast metal gear case and robust motor add to its durability. However, like any tool, it requires proper maintenance to ensure longevity. Keeping the tool clean and periodically checking for wear and tear on the grinding wheels and guard are essential practices.

Final Thoughts

Overall, the Ryobi 18V ONE+ 4-1/2" Angle Grinder is a commendable addition to any DIYer's toolkit, especially for those already invested in the Ryobi ONE+ battery system. Its cordless convenience, combined with a powerful motor and ergonomic design, makes it suitable for a range of applications. However, the rapid battery drain and the need for newer battery models are points to consider.

For users who require a grinder for occasional, light-to-medium duty tasks, this Ryobi model offers excellent value. Its portability and ease of use make it a practical choice for projects where maneuverability and flexibility are paramount. On the other hand, for those who need a grinder for heavy-duty or continuous operation, investing in a more powerful, perhaps brushless model, might be worth considering.

In conclusion, I would recommend the Ryobi 18V ONE+ 4-1/2" Angle Grinder for its balance of power, convenience, and versatility. It's an excellent tool for homeowners and DIY enthusiasts who need a reliable grinder for a variety of tasks without the constraints of a cord. Just be prepared to invest in newer batteries and possibly additional accessories to unlock its full potential.
