DEWALT DCD771C2 vs. Bosch PS31-2A
A 20V MAX kit with a 1/2-inch chuck compared with a smaller 12V MAX drill and 3/8-inch chuck.
By PIQTIVE Editorial Team · Last reviewed September 2, 2026
Quick verdict
The decision in plain language
Choose the DEWALT when a documented 1/2-inch chuck, complete kit, and the 20V MAX platform fit your next projects. Choose the Bosch when a smaller 12V format and 3/8-inch chuck better match furniture assembly and work in tighter spaces. Neither choice is a measured performance winner because PIQTIVE has not run a head-to-head test.

What actually changes the decision
| Factor | DEWALT | Bosch | How to use it |
|---|---|---|---|
| Tight-space handling | Compact full-size format | Smaller 12V format | Bosch is the more intentional compact choice; PIQTIVE has not measured ergonomics. |
| Chuck capacity | 1/2-inch keyless | 3/8-inch keyless | Choose based on the shank sizes required by your bits, not the larger number alone. |
| Listed kit | Drill, two batteries, charger, bag | Drill, two batteries, charger, bag | Both are documented as complete kits; confirm the exact retailer variant. |
| Battery commitment | 20V MAX | 12V MAX | Consider the next tools you may buy before selecting a platform. |

Final recommendation
Match the tool to the job
There is no universal winner.
