How to choose the right one
-
Check Impact Energy Needs
Impact energy determines how fast the tool breaks through masonry. Higher joule ratings mean faster drilling in hard concrete. The DCK 20V Brushless model offers 3.6 joules for heavy demolition. The Bosch 18V model provides 1.4 foot-pounds for lighter tasks. Match this spec to your material hardness. You do not need maximum energy for small anchors. Select a lower rating for better control and battery life on light jobs.
-
Verify Voltage Compatibility
Bare tools require a compatible battery platform. You must own the correct voltage system before purchasing. DEWALT models use 20V MAX batteries. Ryobi and Makita models use 18V systems. Mixing brands is not possible. Check your existing battery pack label. The Bosch 18V tool fits the 18V ecosystem. The CRAFTSMAN V20 fits the V20 line. Ensure your batteries match the tool voltage to avoid damage or non-operation.
-
Review Included Tools
Some kits include multiple tools in the box. The DEWALT 20V MAX SDS kit includes a drill driver and hammer drill. Other models are rotary hammers only. If you need a complete setup, check the included tools list. The Makita 18V LXT kit is a rotary hammer only. The Bosch 18V is also a single tool. Decide if you need additional drills or just the rotary hammer for your specific masonry work.
-
Consider Motor Type
Brushless motors offer longer life and better efficiency. Most listed tools feature brushless technology. The Ryobi 18V Brushless model uses this efficient motor. The DEWALT 20V Max 1-1/8-Inch model is also brushless. The Makita 1-Inch D-Handle is corded and uses an 8-amp motor. Brushless tools run cooler and save battery power. Check the motor type if you plan extensive use. It impacts runtime and durability significantly over time.
-
Assess Weight and Size
Weight affects overhead drilling comfort and fatigue. Lighter tools reduce strain during extended use. The Ryobi 18V Compact model weighs 3.83 pounds. The Makita 1-Inch D-Handle weighs 11.5 pounds due to its corded design. The DEWALT 20V MAX SDS weighs 6.4 pounds. Consider your workspace. Tight spaces may require smaller dimensions. Overhead mounting benefits from lighter weight. Check the weight spec to match your physical comfort and project requirements.
Frequently asked questions

This balance makes it a solid choice for everyday concrete drilling. Its built-in vibration control also aids in maintaining control while working above shoulder height.
What is the maximum chuck size available?
The largest chuck size listed is 1-1/8 inches. This capacity is found on specific DEWALT 20V MAX models. Most other tools on this list use 1-inch, 7/8-inch, or 3/4-inch SDS-Plus chucks. You must verify the chuck size matches your specific bit requirements before purchasing.
Are all listed tools brushless?
Most tools feature brushless motors, but not all. The Makita 1-Inch AVT D-Handle is a corded 8-amp model without a brushless motor designation in the data. The Bosch 3/4-Inch and Ryobi 18V models are explicitly brushless. Brushless motors generally offer better efficiency and longer runtime on a single charge.
