Question 1

What can the DEWALT DCG405 20V MAX angle grinder be used for?

Accepted Answer

The DEWALT DCG405 20V MAX 4.5-inch angle grinder is designed for professional grinding, cutting, and sanding applications. Its 9,000 RPM no-load speed provides efficient performance for compatible tasks, while the compact cordless design improves maneuverability on the jobsite. The included 4-1/2-inch Type 27 guard and secondary handle support controlled operation during suitable grinding and cutting work.

Question 2

How does the KICKBACK BRAKE work on the DCG405 angle grinder?

Accepted Answer

The DCG405 features KICKBACK BRAKE technology that activates when the grinder detects a pinch, stall, or bind-up condition. When engaged, the system quickly stops the wheel, helping reduce the risk associated with kickback. The brake stops the wheel in 2 seconds or less on average, providing an additional safety feature for professionals using the grinder during demanding applications.

Question 3

What does the Power Loss Reset feature do on this angle grinder?

Accepted Answer

The Power Loss Reset feature is designed to help prevent the grinder from accidentally restarting after a power disruption. If power is interrupted while the tool is connected to its battery, the system helps prevent an unintended startup when power is restored. This feature works alongside the KICKBACK BRAKE to provide additional control and protection during professional grinding, cutting, and sanding tasks.

Question 4

Is the DCG405 suitable for working in tight spaces?

Accepted Answer

The DCG405 has a compact cordless design with a slide switch that supports convenient operation in restricted work areas. Its 4.6-pound weight and secondary handle also help provide maneuverability and control during use. Because it operates without a power cord, the grinder can be positioned more flexibly around the workpiece, making it useful for suitable applications where workspace is limited.

Question 5

Which batteries are compatible with the DEWALT DCG405 grinder?

Accepted Answer

The DCG405 is compatible with all DEWALT 20V MAX batteries, allowing users already invested in the 20V MAX cordless platform to use their existing battery packs. The battery and charger are sold separately with this tool-only configuration. Its brushless motor is designed to provide efficient cordless performance and eliminates the need for routine brush replacement.
