BOSCH PS31-2A 12V Max Drill/Driver Kit vs DEWALT DCD771C2 20V MAX Drill/Driver Kit
These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.
BOSCH PS31-2A 12V Max Drill/Driver Kit
Compact drilling in cabinets and tight spaces
Choose this kit for furniture, cabinet hardware and small repairs when compact size and two batteries matter. Its 3/8 in chuck limits larger bit shanks, and a heavier-duty drill is a better fit for long structural screws or masonry holes.

- Two 2.0 Ah batteries, BC330 charger, two screwdriver bits and carrying bag included
- 3/8 in single-sleeve three-jaw chuck
- Two speed ranges: 0 to 350 and 0 to 1,300 rpm
- 265 in-lbs maximum torque and 20+1 clutch settings
Strengths

- Two batteries support alternating between use and charging
- Twenty clutch settings plus a drilling setting provide fastening control
Caveats
- The 3/8 in chuck does not accept larger bit shanks
- No hammer mode for masonry drilling
- Compact design is intended for lighter work rather than long structural screws
