How each tool works
The DCD771C2 listing describes a drill/driver, a tool for drilling and driving with the included bit set, and calls it compact and lightweight for tight areas. The DCF887B listing describes an impact driver, a tool for driving, with a brushless motor, 3-speed settings and a 1/4-inch hex chuck. The two listings describe different tool types, so neither is a direct substitute for the other when the job needs the other tool’s function.
Power and control
The DCD771C2 listing states a high performance motor delivering 300 unit watts out, and says it completes a wide range of applications. The DCF887B listing states a brushless motor and 3-speed settings for application versatility, with precision drive in speed 1 for precision applications and added control. Only the DCF887B listing states speed settings, and only the DCD771C2 listing states a unit watts out figure, so the listings do not share a common power figure for a direct power comparison.
Kit versus tool only
The DCD771C2 listing is a kit: a drill/driver with a 100-Piece accessory set featuring drive and drill bit sets, including Impact Ready, Tough Case, and Pilot Point sets. The DCF887B listing is titled as tool only, with a 1/4-inch hex chuck that accepts 1-inch bit tips, and no bit set is listed with it. A reader who wants bits in the box should weigh the kit contents, while a reader who already owns bits and batteries should check the DCF887B listing for what is included.
Choose the DCD771C2 if
- The job mixes drilling and driving
- A bit set in the kit matters
- A compact drill/driver for tight areas is the priority
- The stated 300 unit watts out motor suits the planned applications
Choose the DCF887B if
- The job is mainly driving fasteners
- Speed settings and precision drive in speed 1 matter
- A 1/4-inch hex chuck with 1-inch bit tips fits the bits on hand
- A stated 3 year limited warranty matters

Garage Fit Check
- Space: both listings state a compact design to fit into tight areas, so check the DCF887B stated dimensions against the tightest spot in the garage.
- Power: both listings state 20V, while only the DCF887B listing states a brushless motor and 3-speed settings.
- Storage: the DCD771C2 kit includes a Tough Case accessory set, so check the bit set contents on that listing before the first job.
- Before the first job: the DCF887B title says tool only, so check that listing for battery and charger inclusion, which it leaves unclear.
- Before the first job: the DCD771C2 listing states no weight and no warranty term, so do not assume those figures from the other listing.
