The DCG412B is an ideal choice for those who need a reliable and efficient tool for everyday cutting and grinding tasks, while the FLEXVOLT model is designed for users requiring more power and advanced features.
Power and Performance
The DCG412B features an 8,000 rpm motor, providing sufficient power for standard cutting and grinding applications. In contrast, the FLEXVOLT 60V MAX* boasts a 13 Amp motor equivalent power and can reach a no-load speed of 9,000 rpm, making it better suited for heavier tasks and larger grinder wheels. This difference in capability shows that while the DCG412B is effective for general use, the FLEXVOLT provides a significant boost in power, making it ideal for professional use or demanding jobs.
Safety Features
Safety is a crucial aspect of any power tool, and here, the FLEXVOLT 60V MAX* stands out with its advanced safety mechanisms. It incorporates a kickback brake that engages when the trigger is released, stopping the wheel in just 1.5 seconds. Additionally, it features E-CLUTCH technology that can shut down the motor in less than a tenth of a second during a pinch or stall. The DCG412B, while less advanced in safety features, includes a 2-finger trigger switch with a lock-off button, ensuring safer operation. The enhanced safety features of the FLEXVOLT make it a preferable option for users working in challenging conditions.
Design and Usability
In terms of design, the DCG412B prides itself on its user-friendly features, such as the Quick-Change Wheel Release, which allows for tool-free wheel removal. The tool-free guard further enhances usability by enabling quick adjustments and positioning. On the other hand, the FLEXVOLT 60V MAX* is built with a focus on performance, featuring a robust design that accommodates larger wheels (4-1/2 inch to 6-inch). While both tools offer two-position side handles for improved control, the FLEXVOLT's design caters to users needing to handle more extensive and demanding projects.
Battery and Runtime
The DCG412B operates on a 20V MAX* lithium-ion battery, providing solid performance for most standard applications. Although runtime details are not specified, DEWALT's lithium-ion batteries are known for their reliability and extended use. Conversely, the FLEXVOLT 60V MAX* utilizes a higher capacity battery system, significantly enhancing its runtime and allowing it to power through heavy-duty tasks without frequent recharging. This increased battery capacity makes the FLEXVOLT more suitable for professionals who require longer operational periods without interruptions.
Price Comparison

This price difference reflects the advanced features and capabilities of the FLEXVOLT model, positioning it as a premium option for high-performance needs. Conversely, the DCG412B is an excellent value for users who require a dependable grinder for everyday tasks without the need for additional features, making it a budget-friendly choice.

The DEWALT DCG412B has a sales rank of 10,196, indicating that it is a popular choice among consumers looking for an effective angle grinder. In contrast, the FLEXVOLT has a sales rank of 57,699, suggesting that while it offers advanced features, it may appeal to a more niche market of users seeking specialized performance. The popularity of the DCG412B may stem from its balance of performance and affordability, making it a go-to option for many DIY enthusiasts and professionals alike.
