Key Features
Fast Concrete DrillingThe 2.1 joules of impact energy helps the DEWALT DCH273B rotary hammer drill quickly into concrete for anchors, rod hanging, and mounting work. Less Handle VibrationSHOCKS Active Vibration Control reduces vibration felt at the handles, which matters when you are drilling overhead or spending the day in concrete. Built for Daily UseA brushless motor and German-engineered mechanism are there for runtime, durability, and steady performance on repetitive drilling and light chipping jobs.
Overview
The DEWALT DCH273B 20V MAX XR brushless cordless 1 in. SDS Plus L-Shape Rotary Hammer, Model DCH273B, is a cordless rotary hammer built for drilling and light chipping in concrete. This is a rotary hammer designed for concrete drilling, anchor installation, rod hanging, and mounting work overhead or in tight jobsite conditions. If you already run DEWALT 20V MAX batteries and need a bare tool for mechanical, electrical, safety, or structural attachment work, this is the right kind of setup.
What makes this tool matter is the balance between power and control. DEWALT rates it at 2.1 joules of impact energy with a no-load speed up to 1,100 RPM, which gives it the punch for common concrete fastening tasks without stepping up to a larger, heavier hammer that is overkill for overhead work. The three-mode selector lets you switch between drill, hammer drill, and chip mode, so the tool can handle standard drilling plus light material removal when needed.
The brushless motor is a practical upgrade, not just a spec-sheet line. It is there to improve runtime and hold up better under repeated use, especially for contractors who spend a lot of time drilling anchors or hanging threaded rod. DEWALT also calls out a durable German-engineered mechanism, which is a big part of why this model has remained a go-to choice for users who want cordless convenience without giving up real rotary hammer performance.
Jobsite comfort is a big part of the story here. SHOCKS Active Vibration Control reduces vibration felt at the handles compared to rotary hammers without that feature, which matters most when you are drilling above shoulder height into slabs or deck work for long stretches. The L-shape layout, side handle, and depth rod all support better control and repeatable hole depth, and the adjustable hook gives you a simple way to hang the tool when you move between locations.
This model uses an SDS Plus tool holder, so it is built around common SDS Plus rotary hammer bits used for anchor holes and mounting applications. It is also battery powered on the DEWALT 20V MAX platform, which makes the DCH273B a strong fit for buyers already invested in that battery system. This is sold as a tool only configuration, so batteries and charger are not included.
DEWALT positions this rotary hammer for rod hanging, seismic and safety attachments, cable tray and strut mounting, clamp mounting, and rail mounting. That makes the ideal buyer pretty clear: electricians, mechanical contractors, HVAC installers, sprinkler crews, general contractors, and serious remodelers who need a compact cordless concrete drilling tool they can run overhead without fighting unnecessary bulk. If your work is mostly anchor holes, hanger installs, and day-to-day concrete fastening, this tool hits the sweet spot.
Made for Overhead Concrete Work
This is the kind of rotary hammer you grab when the work is above you and every extra pound shows up in your shoulders by lunch.
- Lightweight design is called out by DEWALT for rod hanging and mounting applications
- Optimized ergonomic design is aimed at better overhead drilling control
- Side handle and depth rod help with stability and repeat hole depth
Control That Helps You Stay Productive
When you are drilling repetitive anchor holes, comfort is not a luxury. It directly affects speed, accuracy, and how long you can keep working cleanly.
- SHOCKS Active Vibration Control reduces vibration felt at the handles
- Factory-set clutch helps reduce sudden high torque reaction if the bit jams
- Good fit for repetitive fastening prep in concrete and masonry
Three Modes, One Jobsite Tool
The mode dial makes this a more useful jobsite tool than a one-trick concrete drill. You can switch to match the task instead of forcing one setting to do everything.
- Drill mode for rotation-only tasks where appropriate
- Hammer drill mode for concrete drilling
- Chip mode for light chiseling and small correction work

Pro Tip
For anchor and hanger work overhead, set the depth rod before you start your run. It speeds up repetitive holes, keeps your embedment more consistent, and helps the DCH273B do what it is best at instead of turning every hole into a guess.

DEWALT DCH273B Rotary Hammer That Hits the Sweet Spot
The DEWALT DCH273B 20V MAX XR brushless cordless 1 in. SDS Plus L-Shape Rotary Hammer is one of those tools that makes a lot of sense for contractors who drill concrete all week but do not want to drag a cord around for every anchor hole.
- Who it’s for: Electricians, HVAC installers, mechanical contractors, and general trades working overhead in concrete for anchors, rod hanging, and mounting.
- Why it stands out: You get real rotary hammer performance, a brushless motor, three useful modes, and vibration control in a package that is built around day-to-day fastening work.
- Worth knowing: This is a bare tool, so plan on bringing your own 20V MAX battery and charger. It is a strong choice for drilling and light chipping, not a replacement for a larger demolition hammer.
Common Questions
- What type of bits does this tool use? It uses SDS Plus bits.
- Is this a cordless or corded rotary hammer? It is a cordless battery-powered rotary hammer on the DEWALT 20V MAX platform.
- Can it be used for more than drilling? Yes. It has three modes: drill, hammer drill, and chip.
