10 Best Angle Grinders

From leading brands and best sellers available on the web.

Buying Guide for the Best Angle Grinders

Choosing the right angle grinder can make your cutting, grinding, or polishing tasks much easier and safer. Angle grinders are versatile power tools used for various jobs such as shaping metal, cutting tile, or removing rust. The most important thing is to match the tool’s features and capabilities with the type of jobs you plan to tackle. By understanding the main specifications, you'll have a much better chance of finding an angle grinder that fits your needs, is comfortable to use, and will last a long time.
Disc SizeThe disc size tells you the diameter of the grinding or cutting wheel the grinder can use. Larger disc sizes, like 9 inches, allow you to cut deeper and tackle bigger jobs, while smaller discs like 4.5 inches offer more control, precision, and are lighter to handle. If you mostly work on small objects or in tight spaces, go for a smaller disc size. For heavy-duty work with thicker materials, a larger disc is better.
Power (Wattage/Amps)The power measure, usually listed in watts or amps, indicates how strong the angle grinder’s motor is. Higher power allows you to work faster and handle tougher materials without the tool bogging down. Light-duty tasks like sharpening tools require lower power, while heavy-duty construction or metalwork needs more power. Match the tool's power to the hardest material and longest tasks you expect to tackle.
Speed (RPM)Speed, shown as revolutions per minute (RPM), tells you how fast the disc spins. High RPM can cut and grind materials faster, but can also wear discs down quicker and create more heat. Most tasks can be handled by standard speeds, but jobs needing more finesse, like polishing, benefit from adjustable or lower speeds. If you need versatility, look for a grinder with variable speed settings.
Corded vs. CordlessAngle grinders come as either corded, plugging into a wall, or cordless, running on batteries. Corded grinders provide unlimited run time and generally more power, making them better for long jobs, while cordless models offer mobility and convenience, ideal for places far from outlets or quick jobs. Your choice depends on where you usually work and how important portability is.
Safety FeaturesImportant safety features include adjustable guards, anti-restart functions, spindle locks, and side handles for better grip. These keep you safer and make the tool easier to control. If you are new to angle grinders or plan on using them for extended periods, seeking out models with good safety features is a smart choice.
Weight and ErgonomicsHow heavy and comfortable the angle grinder feels will affect how long and accurately you can use it. Lighter grinders cause less fatigue and are easier to handle, especially for overhead or detailed work, while heavier ones can help with larger jobs but may tire you quickly. If possible, try holding a few models before buying, and consider how long you'll be using the tool on typical tasks.
