Product Overview
The DeWalt DCG413FB 20V MAX XR® Flathead Paddle Switch Small Angle Grinder* is a specialized version of the standard DCG413 grinder. The key difference is the “Flathead” gear case design, which is significantly lower in profile than a standard grinder head. This allows the tool to fit into acute angles (as tight as 43 degrees) and other confined spaces where a regular grinder’s head would hit the workpiece before the wheel does.

Key Features
Flathead Gear Case: The defining feature of this model. The gear case is flattened and elongated, allowing for a much deeper reach into tight corners and narrow gaps compared to standard round-head grinders.
Kickback Brake™: A safety feature that stops the wheel in 2 seconds or less when the trigger is released. It also engages if a pinch or stall is detected, shutting the tool down to prevent kickback.
E-Switch Protection™: If the battery runs out or is removed while the trigger is still pressed, the tool will not restart when a fresh battery is inserted. You must cycle the trigger (release and press again) to restart.
Paddle Switch: Features a “dead-man” paddle switch that automatically shuts off the tool if you drop it or lose your grip, which is a requirement on many industrial jobsites.
Two-Stage Trigger: Requires two actions to activate (a safety lever must be pulled before the paddle can be depressed) to prevent accidental startup.

Common Use Cases
This tool is specifically designed for metal fabricators and pipe fitters. It is the problem-solver for grinding welds inside sharp angles, cleaning inside H-beams, or working in tight engine bays where a standard grinder simply won’t fit.
*Note: “20V MAX” refers to the maximum initial battery voltage (measured without a workload), which is 20 volts. Nominal voltage is 18 volts.
