Overview
DEWALT builds this rotary hammer drill around a brushless motor and a keyless chuck, with a vibration control handle to reduce fatigue. The kit lists a side handle, belt hook and depth rod.
The reason to buy is a light, brushless hammer drill with variable speed and reverse. The limitation is that the contents list stops at the tool and its handle, belt hook and depth rod.
Who it's for
A tradesperson with existing batteries who drills anchors and holes in masonry will use the compact size. A buyer starting from zero needs a kit with a battery, or must buy one separately.
Pros and cons
- Vibration control handle
- Variable speed with reverse
- Compact and light
- Battery missing from contents
- Charger not included
- Not a heavy chipping hammer
Performance notes
A hammering action pulses the bit forward as it spins, which breaks up masonry while the flutes clear dust. Speed range, motor power and the battery supplied set how fast it drills, and the vibration handle reduces strain.
