Best Cordless Angle Grinder: Ryobi R18AG-0 Review

Product Overview

I recently got my hands on the Ryobi R18AG-0 ONE+ Angle Grinder, and I have to say, it has quickly become one of my go-to tools for various DIY projects. This cordless angle grinder is part of Ryobi's ONE+ system, which means it’s compatible with over 150 other tools in the lineup. Priced at around $115 to $120, it’s a solid investment for anyone looking to tackle light to medium grinding and cutting tasks without the hassle of cords.

Notable Features and Benefits

One of the standout features of the Ryobi R18AG-0 is its tool-less wheel guard, which allows for quick and easy adjustments. I found this incredibly convenient when switching between tasks. The Gripzone™ overmold provides a comfortable grip, making it easier to handle during extended use. Plus, the 3-position auxiliary handle is a game-changer for versatility, allowing me to adapt the tool to my preferred working position.

Since this is a bare unit, I paired it with the Ryobi 4.0Ah battery, which I highly recommend for superior power and runtime. The performance is impressive, and I appreciate that it’s lightweight at just 2.62 kg, making it easy to maneuver.

In-depth Analysis and Performance Evaluation

Having used the Ryobi R18AG-0 for several projects, I can confidently say that it performs exceptionally well. The 7500 RPM speed is more than sufficient for cutting through metal, masonry, and even concrete. I recently used it to cut some 4mm steel plates, and it handled the job like a champ—no bogging down or overheating, which I’ve experienced with other brands in the past.

One thing I did notice is that the dead-man switch can be a bit of a nuisance. You have to keep it depressed for the grinder to operate, which can be inconvenient when working in awkward positions. However, the overall balance and design of the tool make it easy to hold, even for extended periods. The vibration isolation is also noteworthy; I didn’t experience the discomfort that often comes with using grinders for long stretches.

Recommendation for Buyers

If you’re in the market for a reliable and efficient cordless angle grinder, I wholeheartedly recommend the Ryobi R18AG-0. It’s perfect for DIY enthusiasts and professionals alike, especially if you already own other Ryobi tools. The ability to share batteries across the ONE+ system adds a level of convenience that I truly appreciate. Just make sure to invest in a good battery, like the 4.0Ah, to get the most out of this tool.

Buyer’s Guide

When considering the Ryobi R18AG-0, here are a few things to keep in mind:

1. Battery Compatibility: Ensure you have a compatible Ryobi battery. The 4.0Ah battery is ideal for optimal performance.

2. Intended Use: This grinder is best suited for light to medium tasks. If you plan on heavy-duty work, you might want to look at more powerful options.

3. Weight and Balance: At 2.62 kg, it’s lightweight, but consider how it feels in your hand. The Gripzone™ overmold really helps with comfort.

4. Switch Type: Be aware of the dead-man switch. If you’re used to grinders with a locked-on switch, this might take some getting used to.

5. Accessories: While the grinder comes bare, consider purchasing a cutting and grinding set to get started right away.

Overall, my experience with the Ryobi R18AG-0 has been overwhelmingly positive, and I can’t wait to see what other projects I can tackle with it. If you’re interested in purchasing this tool, you can find it here.
