DEWALT DCG405 is an 18 V XR cordless brushless angle grinder built for cutting, grinding, sanding and surface preparation using 125 mm (5″) discs. It’s supplied as a bare machine tool only, meaning batteries and charger are not included, giving you flexibility if you already have DEWALT XR lithium–ion batteries.
⚡ Core Features
🔋 Brushless Motor Technology
The DCG405 uses a brushless motor for improved efficiency, longer runtime, and greater durability compared with brushed models — helping you get more work done per charge.
🛠 Flat‑Head Gear Case
This grinder features a flat‑head gearbox that allows better access in tight or constrained spaces, making it ideal for flush cutting and angled work.
⚙️ Compact & Ergonomic Design
Its slim body with rubber over‑mould provides enhanced grip and comfort, while the adjustable side handle (2 positions) gives you control during long cutting or grinding sessions.
