Designed for users such as plasterers, tilers, landscapers, flooring contractors and general builders, the DeWalt DCD240 is a Flexvolt paddle mixer, making it one of the only cordless mixing drills on the market. The high power Flexvolt battery system provides the DCD240 with equivalent performance to a 1.8kW corded tool, and means mixing applications can be carried out on site without need for a power supply. The DCD240 uses an M14 accessory connector, enabling it to be used with standard mixing paddles, one of which is supplied with the tool. It has an adjustable 5 position speed dial which enables the machine to be run at 300, 450, 550, 650 or 725 RPM. When changing speeds the motor ramps up or down slowly to enable the operator to maintain sufficient control and prevent splashes. The DCD240 also has a lock of switch which helps to prevent accidental starting, e.g when changing the battery.
