Core Performance & Features The DeWalt DCG405FN is powered by a high‑efficiency brushless motor, delivering up to 9,000 RPM for fast metal cutting and grinding applications. The ultra‑flat gearbox head allows work in acute angles down to 43°, providing superior access in tight spaces. The electronic clutch and E‑Clutch brake help protect the user from kickback reactions and stop the disc in under two seconds for enhanced control. Mesh debris covers restrict dust from entering the motor to extend tool life, and the rubber overmould provides a secure grip during extended use. Bare tool only — battery and charger sold separately.

Target Audience & Use Cases Professional metal fabricators, welders, ironworkers, automotive technicians, construction crews, and serious DIY users. Ideal for cutting metal pipes, rebar, angle iron, grinding weld seams, removing rust, and surface preparation in confined spaces where standard angle grinders cannot fit, such as tight corners, narrow channels, and acute angle metal fabrication work.

Runtime & Compatibility Compatible with all DeWalt 20V MAX batteries (sold separately). For maximum runtime on demanding applications, pairing with high‑capacity XR or FLEXVOLT batteries is recommended. The brushless motor maximizes runtime per charge, and the bare tool design allows users to leverage existing 20V MAX batteries from their collection. Battery and charger sold separately.

Ideal Customer Profile Professional tradespeople and advanced DIY users who regularly work in tight spaces and require a cordless angle grinder that delivers corded‑equivalent performance without sacrificing access or control. Users already invested in the DeWalt 20V MAX battery platform seeking a high‑performance bare tool for daily metal cutting, grinding, and surface prep tasks in confined environments.

Final Summary The DeWalt DCG405FN combines 9,000 RPM power with a low‑profile flat head design for exceptional access in tight spaces. With E‑Clutch brake, electronic kickback protection, and dust‑protected brushless motor, it delivers professional‑grade cutting and grinding performance for metal fabrication, automotive repair, and construction applications where portability and reach are essential.
