DEWALT Rotary Hammer Specs Compared
Weight and Portability
You should consider how much weight you will carry all day. The DEWALT 20V MAX 1-Inch Cordless Rotary Hammer weighs 5 lbs. The DEWALT 20V Brushless 1-Inch D-Handle Rotary Hammer weighs 5.86 lbs. Both tools are bare tools, so this is just the motor housing. The lighter model reduces fatigue on ladders or in tight spaces. If you drill many holes in concrete, every ounce matters. The 5 lb tool gives you a slight advantage for long shifts. You will feel less strain in your wrist and shoulder. Choose the lighter option if you move around the job site frequently.
Physical Dimensions
Size matters when you work in confined areas. The first model measures 16.2 inches in length, 9 inches in width, and 4 inches in height. The second model is longer at 19 inches, narrower at 8 inches, and shorter at 3.5 inches. The longer body of the second tool might hinder access in tight corners. The wider first model may feel bulkier in your grip. However, the second model claims compact size for restricted areas. You need to check if the extra length helps or hurts your specific tasks. The first model offers a more balanced footprint for general use.
Strokes Per Minute
Speed affects how fast you complete holes. The second product lists 0 to 5,500 strokes per minute. The first product does not list this specific metric in its provided data. Both deliver 2.6 Joules of impact energy, which is the force behind each blow. Higher strokes per minute usually mean faster drilling in softer materials. If the first model has a lower rate, it might take longer. You should assume the second model offers faster cycling for efficiency. This spec is crucial for high-volume drilling projects. The listed BPM gives the second tool a clear performance edge.
Included Accessories
You get different accessories with each bare tool. The first model includes a 360° side handle and a depth rod. The second model data does not list any included accessories. A side handle is essential for controlling the torque of a rotary hammer. The depth rod helps you mark consistent hole depths. Without these, you might need to buy them separately. The first model provides immediate usability for common tasks. The second model requires you to source these items yourself. This inclusion adds practical value and saves you from extra purchases.
Power Source Compatibility
Both tools run on the DEWALT 20V MAX battery platform. This means you can use the same batteries for both if you already own them. The first model is labeled 20V MAX. The second model is labeled 20.0V. These are functionally identical in the DEWALT ecosystem. You do not need new batteries for either choice. This compatibility is a major advantage for existing DEWALT users. You can swap batteries between tools seamlessly. The power source does not differentiate the two models significantly. You can focus on weight and size instead of battery needs.
Motor Technology
Both tools feature brushless motors. This technology offers longer runtime and increased durability compared to brushed motors. The first model highlights a durable German-engineered mechanism. The second model also mentions a durable German-engineered mechanism. Both claim optimized performance for hard concrete. The second model specifically notes maintaining speed without bogging down. This suggests robust power delivery under load. Since both share the same core motor type and engineering claims, the performance difference is minimal. You get similar efficiency and lifespan from either choice. The motor tech is a tie between the two.
Which DEWALT Rotary Hammer Fits Your Job
Professionals needing lightweight tools for all-day use
The DEWALT 20V MAX 1-Inch Cordless Rotary Hammer weighs just 5 lbs. This lighter weight reduces fatigue when you carry the tool up scaffolding or across large job sites. You get the same 2.6 Joules of impact energy as the heavier model, ensuring fast drilling in concrete without the extra burden on your body during long shifts.
Users drilling in tight or restricted spaces
The DEWALT 20V Brushless 1-Inch D-Handle Rotary Hammer has a compact width of 8 inches and a height of 3.5 inches. These smaller dimensions allow you to access space-restricted areas where bulkier tools cannot fit. You maintain full power with 0 to 5,500 strokes per minute, even in confined spots where maneuverability is critical for your work.
Contractors prioritizing balance and control
At 5 lbs, this model offers a more balanced feel compared to the 5.86 lb alternative. The 16.2-inch length provides a comfortable grip for the D-handle configuration. You benefit from a rotating dial to switch between drill, hammer drill, and chip modes. This setup helps you maintain precise control when installing structural connections or mounting steel stanchions in various orientations.

Frequently asked questions
Does the DEWALT 20V MAX rotary hammer include batteries?
No, this model is sold as a bare tool. You must purchase compatible 20V MAX batteries separately. This design allows you to use your existing battery inventory if you already own other DEWALT 20V tools. It keeps the initial tool cost lower for users who already have the power source.
What type of drill bits does the DEWALT 20V MAX SDS Plus accept?
It accepts SDS-Plus bits. The chuck size is 1 inch, which is standard for this bit type. SDS-Plus bits lock into the chuck securely for efficient hammering action. This compatibility allows you to use a wide range of standard masonry bits for drilling into concrete or brick.
Which DEWALT rotary hammer is better for structural connections?
The DEWALT 20V MAX 1-Inch Cordless Rotary Hammer is best for structural connections and rod hanging. It is designed for professionals needing high impact energy for heavy-duty structural work. The lighter weight of 5 pounds also helps reduce fatigue during long periods of overhead or repetitive drilling tasks.
Is the D-handle model heavier than the pistol grip version?
Yes, the D-handle model weighs 5.86 pounds. The pistol grip version weighs 5 pounds. The D-handle design offers more stability for heavy-duty concrete drilling. You should choose the heavier model if you already have batteries and prefer the control provided by the D-handle configuration for hard materials.
Can I use this tool with my existing DEWALT batteries?
Yes, both models are part of the DEWALT 20V MAX system. They share the same 20V power source specification. If you own other DEWALT 20V tools, you can likely use your existing batteries with either rotary hammer. Check your battery compatibility to ensure they fit the tool's battery slot.
What is the impact energy of these DEWALT rotary hammers?
Both tools deliver 2.6 Joules of impact energy. This level of energy is suitable for drilling into concrete and masonry. The identical impact energy means both models provide similar hammering power. The choice between them depends more on handle style and weight rather than raw impact force.
