DeWALT DCD778B 20V MAX Brushless 1/2 in. Compact Cordless Hammer Drill/Driver, Tool Only

Key Features

Brushless Efficiency

The brushless motor helps the DeWALT DCD778B hammer drill run longer and waste less battery power than a brushed tool. That matters when you are drilling and driving all day and do not want to swap batteries any more than necessary.

Secure Bit Grip

A 1/2 inch ratcheting chuck holds bits tightly so they stay put under load. That gives you better control when drilling holes or driving fasteners in wood, metal, or masonry.

Compact and Light

At 2.5 pounds, this compact cordless hammer drill is easier to handle overhead, inside cabinets, and in other tight spots. Less weight means less arm fatigue by the end of the day.

Overview

The DeWALT DCD778B 20V MAX Brushless 1/2 in. Compact Cordless Hammer Drill is a bare tool built for drilling, hammer drilling, and fastening across a wide range of jobsite tasks. This is a cordless hammer drill designed for general drilling, masonry drilling, and screw driving. Model Number: DCD778B. If you need one drill that can handle wood, metal, light masonry, and everyday fastening without dragging a cord around, this is the kind of tool that earns its spot in the truck.

On paper, the numbers are straightforward, but they matter in real use. The brushless motor delivers 340 unit watts out, with a top speed of 1,750 RPM and up to 29,750 beats per minute in hammer mode. In plain terms, that gives you the speed for general drilling and the impact action needed when you have to get into masonry. The two-speed transmission helps you shift between higher-speed drilling and slower, more controlled fastening, so you are not stuck using one setting for everything.

The 1/2 inch ratcheting chuck is one of the more important details here. A better chuck means better bit retention, especially when you are leaning into tougher material or switching between drilling and driving. DeWALT also gives you 15 clutch settings, which is useful when you need to keep from overdriving screws in finish material, cabinet work, or lighter-duty installs. That makes this tool more versatile than a basic drill that only does one job well.
