Buying Guide
Choosing Your Cordless Angle Grinder
Cordless angle grinders offer freedom and flexibility for various grinding and cutting tasks. Selecting the right one involves considering several key features.
Voltage & Power
The voltage determines the power. 18V and 20V models are common for DIY users, providing sufficient power for most tasks. Higher voltages, such as 36V or 40V, offer more power and are suitable for tougher applications and professional use.
Disc Size
Angle grinders come in different disc sizes, typically ranging from 4.5 inches to 6 inches. The 4.5-inch size is versatile and suitable for many projects. Larger discs offer deeper cuts but may require more power and control.
Battery & Charger
Battery capacity, measured in Amp-hours (Ah), dictates the runtime. Consider the included charger. A fast charger minimizes downtime. Also, check if the battery is compatible with other tools you own from the same manufacturer.
Frequently Asked Questions
What are the main advantages of a cordless angle grinder?
Cordless angle grinders offer superior portability and convenience, allowing you to work in areas without access to power outlets. They provide greater freedom of movement and reduce the risk of tripping hazards associated with cords, making them ideal for various on-site tasks.
How long does the battery last on a typical cordless angle grinder?
Battery life varies depending on the voltage and amp-hour (Ah) rating of the battery, along with the type of material being cut or ground. Generally, a fully charged 18V 5.0Ah battery can provide about 20-30 minutes of continuous runtime under moderate use.
What size grinding wheels are compatible with most cordless angle grinders?
Most cordless angle grinders are designed to accept 4.5-inch or 5-inch grinding wheels, cutting discs, and flap discs. Always check the grinders specifications to ensure compatibility with your desired accessories and to ensure safe operation.
What safety features should I look for in a cordless angle grinder?
Prioritize features like a safety guard for protection from sparks and debris, a tool-less guard adjustment for easy changes, and a paddle switch for quick shut-off. Consider models with an electronic brake that stops the wheel quickly when the switch is released for added safety.
Can I use a cordless angle grinder for heavy-duty tasks?
While cordless angle grinders are convenient, their power is often less than that of corded models, limiting their use in demanding tasks. They are suitable for light to medium-duty applications such as cutting metal pipes, grinding welds, and removing rust; for continuous heavy usage, a corded grinder may be a better option.
Final Thoughts
In conclusion, the cordless angle grinder offers impressive performance for various tasks. We found the Milwaukee 2880-20 provided exceptional power for cutting through metal, while the DEWALT DCG412B excelled in balancing power and maneuverability.
The Bosch GWS18V-45CN delivered excellent value, especially considering its price point and extended runtime. Ultimately, selecting the right angle grinder hinges on your individual needs.
