Tired of grinders that overheat mid-job, lack the muscle for tough metal work, or leave your hands sore after hours of use? The DEWALT DCG405FN is the game-changing solution you’ve been waiting for.

Engineered for professional metalworkers, fabricators, contractors, and serious DIYers, this 125mm (5") brushless angle grinder delivers industry-leading power, control, and durability in a compact, ergonomic design — perfect for cutting, grinding, finishing, and surface prep on the job site, in the workshop, or at home.

5 Standout Features That Make It a Must-Have

High-Performance Brushless Motor for Unmatched Power & Longevity

Powered by DEWALT’s legendary brushless motor, the DCG405FN delivers consistent, high-speed power to tackle even the toughest metal cutting, grinding, and surface prep tasks. The brushless design runs 50% cooler than traditional brushed motors, lasts up to 2x longer, and requires zero maintenance, so it’s ready to work as hard as you do, day in and day out.

125mm (5") Wheel Capacity for Ultimate Versatility

Equipped with a 125mm (5") wheel capacity, it’s fully compatible with a full range of cutting discs, grinding wheels, flap discs, and wire wheels. One tool handles everything from metal fabrication and pipe cutting to rust removal, weld cleaning, tile cutting, and concrete surface prep — no need for multiple tools.

Ultra-Compact, Ergonomic Design for Tight Spaces & All-Day Comfort

Its slim, streamlined body and contoured, rubberized overmold grip fit perfectly in your hand, drastically reducing user fatigue and ensuring maximum control, even during extended use. The low-profile gear housing and balanced weight distribution let you work in tight engine bays, confined construction gaps, and awkward angles with ease, where larger grinders can’t reach.

Advanced Safety & Tool-Free Adjustability

Built with a tool-free adjustable guard for quick, easy wheel changes and angle adjustments, plus a durable auxiliary side handle for enhanced control and vibration reduction. The dust-sealed switch and motor housing protect against job-site debris, extending tool life, while the anti-kickback brake adds an extra layer of safety for every operation.

DEWALT Job-Site-Proof Durability

Built to DEWALT’s rigorous industrial standards, the DCG405FN is drop-tested, dust-resistant, and engineered to withstand the harshest job-site conditions. It’s not just a tool — it’s a reliable workhorse that’s built to last, backed by the same quality that professionals trust worldwide.
