The grinder is powered by a 20-volt battery, which is not included and must be purchased separately. With a disc size of 4.5 inches and a no-load speed of 3450 RPM, it can handle various grinding tasks effectively.

Additional safety features include the Kickback Brake and E-Switch Protection, which make this grinder a safer option for users.

DEWALT is a reputable brand in the tools category, and the product comes with a 3-year limited warranty, offering peace of mind regarding its durability. A significant drawback is that the tool does not come with the necessary battery and charger, which must be purchased separately. This can be an added expense if you don’t already have compatible DEWALT batteries. If you are looking for a reliable and safe cordless grinder for grinding tasks, and already own DEWALT 20V batteries, this tool could be a good fit.

The DEWALT 20V MAX Angle Grinder and Die Grinder set offers a powerful and versatile solution for various grinding tasks. This set includes two tools: the DCG413 Small Angle Grinder and the DCG426 Variable Speed Die Grinder, both powered by a 20V MAX XR 5Ah lithium-ion battery. This battery provides ample power and runtime, making it suitable for extended use without frequent recharges. Additionally, the included 8 Amp fast charger ensures quick recharging times, so you can get back to work promptly.

The DCG413 features a 4.5-inch disc size, which is standard for most angle grinders and allows for compatibility with a wide range of grinding and cutting discs. The kickback brake is a notable safety feature, stopping the wheel in 2 seconds or less to prevent accidents. The two-stage trigger adds an extra layer of safety by requiring two actions to activate the tool. Meanwhile, the brushless motor extends the tool's lifespan and enhances efficiency.

For the DCG426 Die Grinder, the variable speed trigger allows for precise control, reaching speeds of up to 25,000 RPM. The dual-position rocker switch enables multiple handle grasping points, improving ergonomics and user comfort. Both tools are lightweight and compact, with the total weight of the set being approximately 11.71 pounds. However, some users may find the combined weight slightly cumbersome for prolonged use. DEWALT is a reputable brand known for its durable and reliable tools, and this set is no exception.

The DEWALT FLEXVOLT 60V MAX* Angle Grinder (DCG418X2) is a powerful cordless grinder designed for heavy-duty tasks. It features a 60V battery that provides ample power, with up to 2300 watts output and a no-load speed of 9000 RPM. This makes it suitable for cutting, grinding, and finishing jobs. The grinder supports disc sizes from 4-1/2 inches to 6 inches, offering versatility for different applications. The inclusion of 2 Lithium-Ion batteries ensures prolonged usage and convenience as you don't need to frequently recharge during work sessions.

Weighing 16.15 pounds, it may be on the heavier side, but this weight contributes to stability during operation. However, it could be tiring for prolonged use. Safety features are robust, with a Kickback Brake and Anti-Rotation E-CLUTCH System to prevent accidents. The Kickback Brake engages rapidly in case of pinch or stall, while the E-CLUTCH shuts down the motor instantly if a problem is detected. Ergonomics are decent, with a side handle included for better control, although the weight may affect maneuverability.

DEWALT’s standing as a reputable brand, along with a 3-year limited warranty, 1-year free service contract, and a 90-day money-back guarantee, adds to the product’s reliability. On the downside, it is relatively expensive and might be overkill for light or occasional use. Additionally, the weight could be a drawback for some users. In conclusion, this grinder is ideal for professionals requiring a powerful, reliable tool for demanding jobs, but might be excessive for casual users.
