Overview
The DEWALT DCH172B sits in DeWalt's DCH line, which denotes SDS-plus rotary hammers rather than standard drill drivers, and its 1100 RPM speed alongside a heavier 4.6 lb body fits that profile. It runs on DeWalt's 20V platform with a 2 amp motor.
The model prefix matters more here than the generic drill title: DCH tools are built to hammer-drill into masonry and concrete using an SDS-plus bit system, a different job than a standard DCD drill driver handles. The lower 1100 RPM and added weight compared with a typical drill driver both line up with that rotary hammer function. No seller description accompanies this listing to confirm impact energy or included accessories beyond the model line itself.
- DeWalt DCH-series 20V SDS-plus rotary hammer
- Speed: 1100 RPM, 2 amp motor
- Item weight: 4.6 pounds
- Dimensions: 11.5 x 8.54 x 4 inches
Who it's for
Suited to someone drilling into concrete, brick or block who needs the hammering action an SDS-plus tool provides. Not the right choice for a buyer who just wants a light drill driver for wood and drywall screws, where a standard DCD-series DeWalt would fit better.
Strengths and trade-offs
Drawn from this product's published specifications.
- DCH line indicates purpose-built SDS-plus rotary hammer for masonry
- 20V platform shares batteries with other DeWalt tools
- Strong rating (4.7) across 1,440 reviews
- Heavier at 4.6 lb than a standard drill driver
- Not ideal for light wood or drywall screws
- No description confirming impact energy or included bit
Performance notes
Rotary hammers like the DCH172B combine rotation with a piston-driven hammering action to break through masonry, which is why the RPM figure of 1100 reads low next to a standard drill driver; the hammering, not raw spin speed, does the work. At 4.6 lb and running on DeWalt's 20V platform, it stays compact for its category, measuring about 11.5 x 8.5 x 4 inches.
