The DEWALT 20V MAX* Angle Grinder Tool (DCG413B) is a powerful and efficient option in the brushless angle grinder category. It features a brushless motor, eliminating the need for brush changes and improving durability. The tool operates at a maximum rotational speed of 3450 RPM, which is suitable for various grinding tasks. The disc size is 4-1/2 inches, which is versatile for different applications without being overly cumbersome. This grinder is battery-powered, using 20V lithium-ion batteries, though the batteries are not included with the tool, which is a point to consider for those who need a complete package right away.
The design is fairly compact with dimensions of 12.2 inches in length, 4.7 inches in width, and 6 inches in height, and it weighs 3.75 pounds, making it relatively lightweight and easy to handle. Ergonomically, it includes features like a two-stage trigger to reduce the risk of accidental activation and improve user safety. Safety features are a strong point of this model, with a brake that stops the wheel in 2 seconds or less and a kickback brake that engages in the event of a pinch or stall, reducing potential hazards. Additionally, the E-Switch Protection ensures that the tool won't unexpectedly restart after a power interruption.
One downside is the absence of included batteries, which could be inconvenient for users without compatible ones. The build quality is robust, using plastic and metal materials, and it comes with a 3-year limited warranty. This tool is well-suited for those needing a reliable and safe angle grinder for various grinding tasks.
The Milwaukee 2880-20 M18 FUEL Brushless Cordless Small Angle Grinder stands out with its robust brushless motor and impressive design. With an 18-volt battery power source and a maximum rotational speed of 8500 RPM, it's built to deliver strong performance. The 4-1/2 and 5-inch disc compatibility means it’s versatile for various grinding tasks. A significant strength is its battery life, especially considering it's compatible with all M18 batteries, making it convenient for users already invested in Milwaukee's M18 system.
Additionally, the anti-vibration side handle and electronic clutch for kickback protection are notable safety and comfort features, enhancing user comfort and safety during prolonged use. However, it is important to note that the tool does not come with the battery, which is an added expense for new users. At 4.99 pounds, it strikes a good balance between being lightweight and sturdy, but some users might still find it slightly heavy for extended use.
The overload protection feature aims to maximize motor life, making it durable and reliable. This grinder is particularly suited for users who need a powerful, durable, and cordless option for heavy-duty tasks, but it may not be the best choice for those on a tight budget due to the need for separate battery purchase.
The Makita XAG04Z 18V LXT® Lithium-Ion Brushless Cordless Angle Grinder is a versatile tool that caters to users looking for efficient and reliable performance. One of its standout features is the Automatic Speed Change technology, which adjusts speed and torque during operation, ensuring optimum performance. Additionally, the Active Feedback-sensing Technology (AFT) enhances safety by automatically shutting off the motor if the wheel's rotation is abruptly stopped.
The brushless motor design eliminates carbon brushes, allowing for cooler and more efficient operation, thus extending the motor's lifespan. The motor is electronically controlled to optimize battery energy use, potentially offering up to 50% longer run time per charge, which is beneficial for extended projects. With a maximum rotational speed of 8500 RPM, it can handle various grinding and cutting tasks effectively. The disc size options of 4-1/2” and 5” provide flexibility for different applications.
At 4.8 pounds, it offers a relatively lightweight design, contributing to better ergonomics and ease of handling. However, it is worth noting that the tool is sold without batteries, which means additional purchases are necessary to start using it. Safety features and ergonomics are well-addressed, making it suitable for both professional and DIY users. The Makita XAG04Z is a robust choice for those needing a capable and safe angle grinder, but be prepared for the extra cost of batteries.
