Ryobi 18V ONE+ Lithium High Performance Starter Kit with Free HP Compact Brushless 1/4" Right Angle Die Grinder

As a DIY enthusiast and professional tool user, I always have an eye out for tools that can simplify my projects while maintaining high performance. The Ryobi 18V ONE+ Lithium High Performance Starter Kit with the HP Compact Brushless 1/4" Right Angle Die Grinder caught my attention for its promise of combining portability with power. After putting this die grinder through its paces, I have some detailed insights to share.

Initial Impressions and Build Quality

Right out of the box, the die grinder gives off a sturdy and well-constructed vibe. The kit includes a set of lithium-ion batteries (2Ah, 4Ah, and 6Ah) along with a charger and tool bag, which is a thoughtful addition for those who need a complete setup. The tool itself is relatively lightweight, especially considering its cordless nature, and fits comfortably in hand. The paddle-style trigger with a built-in safety switch is intuitive to use and ensures that there are no accidental activations.

Versatility and Performance

One of the standout features of this die grinder is its brushless motor, which is engineered for efficiency and longevity. The variable speed paddle switch allows for precise control, making it suitable for a wide range of tasks, from grinding and sanding to polishing and cutting.

The tool boasts four speed modes:
- Mode 1: 10,000 RPM
- Mode 2: 15,000 RPM
- Mode 3: 20,000 RPM
- Mode 4: 22,000 RPM

These settings are easily adjustable via a push button at the base of the tool. This flexibility is invaluable for tasks requiring different levels of finesse and power. For instance, I found the lower speeds perfect for intricate metalwork, while the highest setting was more than adequate for heavy-duty grinding.

Real-World Application

Using the die grinder on various projects, I noticed its performance is robust, especially when paired with the larger battery packs included in the kit. The compact design is a double-edged sword; while it allows for easy maneuverability in tight spaces, it does lead to some compromises. When using smaller battery packs, the tool tends to experience significant RPM drops under load, leading to occasional stalling. This issue is somewhat mitigated when using the larger 6Ah battery, although it does make the tool less balanced and more cumbersome.

Despite these minor setbacks, the tool excels in many areas. The LED light positioned to illuminate the work area is a practical feature, especially in dimly lit environments. I used the grinder for sharpening tools, cutting metal, and even some light sculpting, and it performed admirably across the board. The collet system is user-friendly, and the inclusion of a wrench for bit changes is a nice touch, though I would have appreciated a storage spot for the wrench on the tool itself.

Noise and Ergonomics

One of the pleasant surprises with this die grinder is its relatively quiet operation compared to pneumatic alternatives. The absence of an air hose not only makes the tool more portable but also eliminates the cold handle issue common with air grinders. This makes extended use much more comfortable.

The ergonomic design fits well in hand, though the balance can be off when using larger batteries. The tool's weight is manageable, and the paddle trigger is easy to modulate, allowing for smooth operation even during prolonged tasks.

Safety and Practicality

Safety is a priority with this tool. The variable speed trigger ensures you can start slow and ramp up the speed as needed, reducing the risk of accidents. The safety switch on the paddle trigger is another layer of protection, preventing unintentional starts.

However, the tool does have some practical limitations. For instance, Ryobi advises against using attachments greater than 2 inches in diameter, which can be a constraint depending on your needs. Additionally, while the tool is powerful, it doesn't have the same torque as some of its pneumatic counterparts, which might be a consideration for heavy-duty applications.

Battery Life and Portability

Battery life is always a concern with cordless tools, but the Ryobi die grinder performs well in this regard. The included 2Ah, 4Ah, and 6Ah batteries provide ample runtime for most tasks. The charger included in the kit is efficient, ensuring minimal downtime between jobs.

Portability is one of the strong suits of this tool. The ability to work without being tethered to an air hose or power outlet is liberating, especially for projects that require mobility. Whether working in the garage, on a boat, or even in the field, this die grinder proves to be a versatile companion.

Final Thoughts and Recommendation

In conclusion, the Ryobi 18V ONE+ Lithium High Performance Starter Kit with the HP Compact Brushless 1/4" Right Angle Die Grinder is a solid addition to any tool collection. It offers a good balance of power, portability, and versatility, making it suitable for both DIY enthusiasts and professionals. The tool's compact design, variable speed control, and brushless motor are significant advantages, though the need for larger batteries to avoid performance drops is a minor drawback.

Would I recommend this tool? Absolutely. If you're looking for a cordless die grinder that can handle a variety of tasks with ease and offers the freedom of mobility, this Ryobi model is worth considering. Its strengths far outweigh its limitations, making it a valuable asset for any toolbox.
