I also like that it is part of the 20V Max platform, since I can keep using the same battery system across other Dewalt tools I own.

What I Looked at Before Buying

Before deciding, I focused on a few key points:

  • Brushless motor: I prefer brushless tools because they usually run more efficiently and need less maintenance.
  • Multi-head versatility: I wanted a drill/driver that could adapt to different angles and work areas.
  • Size and weight: I value a tool that feels light enough for overhead work and extended use.
  • Battery compatibility: Since this is a bare tool, I made sure I already had compatible Dewalt 20V Max batteries.
