Angle grinders are indispensable tools for both professionals and DIY enthusiasts. These versatile power tools can handle a myriad of tasks, from cutting through metal and tile to grinding down welds and removing rust. With so many options on the market, choosing the right angle grinder can be daunting. That’s why we’ve put together this comprehensive guide to the best angle grinders of 2024, based on extensive hands-on testing and expert reviews.
Criteria for Choosing the Best Angle Grinders
When selecting an angle grinder, several key factors come into play:
Size and Power: The size of the disc and the power of the motor determine the tool’s capability. For most DIY projects, a 4.5-inch disc with a motor ranging from 7 to 11 amps is sufficient. Larger discs and more powerful motors are better suited for heavy-duty tasks.
Motor Type and Power Source: Angle grinders come in corded and cordless varieties. Corded models generally offer more consistent power, while cordless models provide greater mobility. Brushless motors are preferred for their efficiency and longevity.
Speed and RPM: The speed of an angle grinder is measured in revolutions per minute (RPM). Higher RPMs allow for faster cutting and grinding, but also generate more heat. Most grinders range from 5,000 to 11,000 RPM.
Safety Features: Look for models with features like electronic brakes, kickback control, and safety guards to protect the user from accidents.
Ergonomics and Ease of Use: A comfortable grip, adjustable handles, and lightweight design can make a significant difference in user fatigue and control.
