Overview of the DCD780C2 Dewalt Drill
The DCD780C2 is a 20V MAX* Lithium Ion Compact Cordless Power Drill / Driver Kit by DEWALT. This lightweight and compact device is designed for working in tight spaces for extended periods of time. The high-speed transmission of this cordless drill delivers two-speed variations allowing users to tailor their level of performance to their needs.
The drill comes with advanced technology and innovative features, making it a prime choice for both commercial and residential builders, remodelers, carpenters, woodworkers, electricians, and plumbers. With its extreme durability, performance, and comfort, it allows users to match the tool to the task at hand, increasing the flexibility for a variety of applications irrespective of speed, torque, or power.
Moreover, DEWALT-designed electronics have been integrated into the DCD780C2’s switch to provide maximum life for the tool and battery by protecting them from overheating, overloading, and deep discharge during use. The 20-volt’s lithium-ion batteries offer up to 35% more runtime than existing 18-volt lithium-ion battery technology. The included charger has dual voltage capabilities, and it is compatible with both 12-volt max and 20-volt max DEWALT lithium-ion batteries; the DCD780C2 is also compatible with the 3.0 Ah lithium-ion batteries that are available as replacement packs or come with the premium tools.
The drill’s high-power, high-efficiency motor delivers 350 unit watts out of maximum power for superior performance in light and medium drilling applications. A 1/2-inch ratcheting chuck with carbide inserts provides superior bit-gripping strength—reducing slippage during high-torque applications—thus providing longer tool life. The drill/driver’s two-speed (0-600 RPM and 0-2,000 RPM) transmission allows users to select the appropriate speed for the job at hand and is up to 30 percent faster than current drill/drivers on the market.
Lastly, the compact drill’s design incorporates a slim handle with contoured grip that extends user comfort during long jobs. It also features a bright built-in LED work light above the trigger with a 20-second delay that improves visibility in dimly lit spaces.
