DEWALT Impact Wrench Specs Compared
You can sort these eight models by chuck size. The 3/4-inch DCF964B handles industrial bolts, while the 1/2-inch DCF961B and DCF900B serve heavy construction. The compact DCF923 and DCF921B suit precision work with smaller fasteners. All use 20V power. Some are bare tools for existing battery owners. Others include chargers or work lights.
Motor type and weight also vary. The DCF964B and DCF961B use brushless motors for efficiency. The DCF900P1 kit weighs 11 pounds with a 5.0 Ah battery. Lighter options like the DCF921B weigh 2.76 pounds. Choose based on your torque needs and current battery inventory. This guide ranks them by these published specifications.
Where DEWALT Fits Your Needs
This range covers 3/8-inch, 1/2-inch, and 3/4-inch chucks. You can choose between compact ATOMIC models weighing under three pounds and heavy-duty XR units exceeding nine pounds. Most tools are bare tools, but the DCF900P1 kit includes a 5.0 Ah battery and charger, while several bare tools feature built-in work lights. You will not find 1/4-inch hex drives or corded options here. The lineup focuses on Hog Ring anvil types for quick socket changes. If you need extreme precision with tiny fasteners, the 3/8-inch DCF923 is your smallest choice. For industrial bolts, the 3/4-inch DCF964B provides the largest drive size available in this set.

How to choose the right impact wrench
-
Match chuck size to bolts
The chuck size determines the maximum bolt diameter you can drive. The DCF964B features a 3/4-inch chuck for heavy industrial fasteners. Most models use a 1/2-inch chuck for automotive and construction work. The DCF923 has a 3/8-inch chuck for smaller, precision tasks. Choose the largest chuck that fits your typical hardware. A larger chuck handles more torque but adds bulk. Ensure the anvil type, such as hog ring, matches your sockets for secure attachment during high-speed operation.
-
Check motor type for durability
Brushless motors offer longer life and better efficiency than brushed alternatives. The DCF900B and DCF961B both feature brushless motors for sustained heavy-duty performance. These models are ideal for professional users who run the tool frequently. Brushless designs reduce heat buildup and wear on internal components. This means less maintenance over time. If you need raw power for tough applications, prioritize a brushless motor. It delivers consistent torque without the friction losses of older technology.
-
Compare weight for comfort
Weight affects control during overhead or awkward positioning tasks. The DCF921B weighs just 2.76 pounds, making it easy to handle for extended periods. In contrast, the DCF964B weighs 9.04 pounds, providing stability for high-torque industrial bolts. Heavier tools may cause fatigue during precision work. Lighter models offer better maneuverability but might lack the mass needed for stubborn fasteners. Select a weight that balances your strength requirements with the job type. Consider the tool dimensions as well for tight space access.
-
Decide on bare tool vs kit
Most models are sold as bare tools, requiring you to supply your own 20V battery. The DCF900P1 is a notable exception, including a 5.0 Ah battery and charger. If you already own DEWALT batteries, a bare tool is more cost-effective. The kit suits new users who need a complete setup immediately. Check the included items carefully. Some kits provide only the wrench, while others add work lights. Verify battery capacity to ensure adequate runtime for your specific project duration.
-
Verify voltage compatibility
All listed models operate on the 20V MAX platform. This ensures you can use any compatible DEWALT 20V battery across different tools. The DCF900B and DCF923 both use the same voltage system. This flexibility allows you to mix and match tools without buying new power sources. Ensure your existing batteries match the 20V standard. Higher voltage does not appear in this lineup, so focus on battery capacity instead. Consistent voltage simplifies your inventory and reduces confusion when swapping power sources.
