Overview
DEWALT's DCG416B is a 20V MAX cordless angle grinder sold as a bare tool, rated at 9000 RPM and 1550 watts of motor output, with no battery or charger included.
DEWALT positions this as a 20V MAX cordless grinder aimed at cutting, grinding, and surface prep work that a corded grinder would normally handle. The listed item weight of 16 ounces is unusually light for a complete angle grinder body and likely reflects a component or packaging figure rather than the full tool, so treat that number with caution. As a bare tool (B suffix), a compatible 20V MAX battery and charger are needed separately.
