It achieves a maximum speed of 24,500 RPM, which is sufficient for common tasks like cutting, polishing, and grinding. The 1/4" collet size is standard and compatible with many attachments, giving you good versatility.

In terms of ergonomics, this grinder is compact and lightweight, which helps reduce fatigue when working in tight spaces or for longer periods. The right-angle design also improves access to difficult spots compared to straight grinders. Users generally find it comfortable to hold and maneuver. Durability is a strong point for this Milwaukee tool, as the brand is known for robust construction, and the kit includes two batteries and a charger, which adds convenience and reduces downtime.

A potential drawback is the 12-volt battery, which may offer less power and runtime compared to higher-voltage models, possibly limiting heavy-duty or continuous use. Also, the tool weighs about 1.5 pounds (likely a typo in the 15 pounds listed), which is generally light but important to confirm for comfort. This die grinder suits DIY enthusiasts and professionals who need a portable, reliable grinder for medium-duty jobs, especially where mobility is key. For everyday cutting, grinding, and polishing, this Milwaukee M12 FUEL kit delivers a good balance of power, convenience, and usability.

The DEWALT DCG426B 20V Max Variable Speed Die Grinder is a solid choice for both professionals and DIY enthusiasts looking for a reliable tool for grinding tasks. One of its main strengths is the DEWALT-built brushless motor, which offers efficient performance and a long runtime, making it a dependable option for various projects. The variable speed trigger allows users to reach up to 25,000 RPM, providing versatility for different grinding applications. Additionally, the built-in LED lights are a thoughtful feature, helping illuminate dark work areas for improved visibility and precision.

Ergonomically, the grinder offers multiple handle grasping options and a dual-position rocker switch, which can enhance user comfort and control during operation. This makes it suitable for extended use without causing too much strain on the hands.

On the downside, being a cordless model, it requires batteries that are not included with the purchase, which means you’ll need to invest in those separately if you don’t already own them. The battery dependency can also limit continuous use if you don’t have spares charged and ready. Additionally, some users might find the tool a bit heavier compared to other lightweight alternatives, which could affect maneuverability in tighter spaces. In terms of noise and vibration, while most users report satisfactory performance, die grinders typically produce a significant amount of both, so wearing appropriate safety gear is recommended. The product comes with a 3-year limited warranty, which adds to the value, ensuring peace of mind for users regarding its durability.

The DEWALT DCG426B is a powerful and versatile die grinder that excels in performance and usability, making it suitable for those who frequently take on grinding tasks, though potential buyers should consider the need for additional batteries and its weight when making a decision.

The 1/4-inch collet securely holds accessories, with an optional 1/8-inch sleeve for added flexibility. Users will appreciate the ergonomic design, featuring a convenient paddle switch with a lock-on button for comfortable, prolonged use. Despite being lightweight at 4.7 pounds, it's built with durability in mind, backed by a 3-year limited warranty.

Some users might find the noise and vibration levels typical for this type of power tool. Additionally, as a corded model, it may not offer the same level of portability as cordless alternatives. This grinder is well-suited for those needing a powerful, versatile, and durable tool, particularly in environments where AC/DC power options are beneficial.
