10 Best Angle Grinders

The DEWALT 18V XR Brushless 125mm Angle Grinder is a battery-powered tool designed for those who need a reliable and portable grinder without being tethered to a power outlet. Its 18V brushless motor offers strong power and better durability compared to older brushed motors, which means less maintenance and a longer working life. The 125mm disc size is a common and versatile choice, suitable for general cutting and grinding tasks around the home or on-site. It spins at a high speed, providing efficient cutting and grinding performance.

A standout safety feature is the electronic clutch that helps reduce kickback if the disc gets pinched, making it safer and easier to control, especially for users who may not be very experienced. The grinder also includes mesh debris covers to protect the motor from dust, which is excellent for working in dusty conditions and helps prevent overheating. Weighing about 2.4 kg, it is reasonably lightweight but sturdy, and the rubber overmould grip plus the adjustable side handle improve comfort and control during use, helping reduce fatigue during longer jobs.

The tool is sold without a battery or charger, so you'll need to purchase those separately if you don't already have compatible DEWALT 18V batteries. This angle grinder is a solid choice for DIY enthusiasts and professionals looking for a cordless grinder that balances power, safety, and ease of use. For heavy-duty industrial applications requiring continuous operation, corded models might be more suitable, but for portability and good performance in most cutting and grinding tasks, this DEWALT model is well suited.

The Ryobi R18AG-0 ONE+ Angle Grinder is a battery-powered tool that offers flexibility and convenience for users who prefer cordless operation. With an 18V lithium-ion battery, it's designed for portability, although you should note that it doesn't come with a battery, which could be a downside if you don't already own a compatible Ryobi ONE+ battery. It weighs 2.62 kg, which is relatively lightweight, and features an ergonomic design with Gripzone™ over mould, enhancing user comfort during prolonged use.

The grinder boasts a powerful motor with a speed of 7500 RPM, making it suitable for a range of DIY tasks. Its 4-horsepower motor delivers adequate performance, but for more demanding jobs, users might require a higher-powered model. The tool-less wheel guard allows for quick adjustments, a handy feature that enhances usability and safety.

While it ranks well in customer satisfaction with a 4.7-star rating, the absence of included batteries could be inconvenient and add to the overall cost if you need to purchase them separately. Featuring a 3-position auxiliary handle, this angle grinder offers versatile handling options, which can be particularly beneficial when working on various tasks from different angles.

In conclusion, the Ryobi R18AG-0 ONE+ is a versatile tool well-suited for general DIY enthusiasts looking for a portable, easy-to-use angle grinder. It's particularly beneficial for those already invested in the Ryobi ONE+ battery system. However, those looking for a tool for heavy-duty or professional use might need to consider other options with more power and features tailored to demanding applications.

The Makita DGA504Z 18V Li-ion LXT Brushless 125mm Angle Grinder is a solid choice for heavy-duty grinding tasks. Its 125mm disc size is versatile for most applications, and the brushless motor delivers a strong performance with a speed of 8500 RPM. The grinder is powered by an 18V battery (not included), which offers good mobility but requires purchasing a battery and charger separately if you don't already own them.

Weighing 2.5 kg, it's relatively lightweight and ergonomically designed, making it comfortable to handle during extended use. Key safety features include an anti-restart function to prevent accidental starts and an automatic torque drive that adjusts speed for optimal performance. It also includes a spindle lock for easy wheel changes and can be connected to a dust extraction system, though the necessary dust collecting cover is not included.

The slide-type switch with a lock-on function adds to the convenience. However, it's not compatible with Makita's G-Series batteries, so compatibility with existing batteries should be checked. This model is best suited for users who need a reliable, portable angle grinder for heavy-duty applications and already have or are willing to invest in Makita's LXT battery system.
