DeWALT 20V Max XR 1/2 in. High Torque Impact Wrench with Hog Ring Anvil (Tool Only) is a heavy-duty cordless impact wrench engineered for demanding fastening tasks including large pipe flanges, grooved couplings, wheel lugs, and concrete anchor bolt setting. Powered by DeWALT's 20V Max Lithium Ion battery platform (battery sold separately), this tool delivers serious torque output in a cordless format - giving professionals the freedom to work without a tethered cord on job sites where access and mobility matter. With its hog ring anvil, variable speed trigger, and built-in LED work light, the DCF900B is designed to handle a wide range of high-torque impact wrench applications with precision and control.

Key Features

• 1,030 ft-lbs. of max fastening torque and 1,400 ft-lbs. of max breakaway torque - delivers the raw power needed to drive and remove fasteners on pipe flanges, grooved couplings, wheel lugs, and concrete anchor bolts, reducing the effort required on large-scale or stubborn fastening jobs.
• PRECISION WRENCH mode - designed to help prevent overtightening in forward and fastener run-off in reverse, giving users greater control and reducing the risk of damaged fasteners or connections.
• 4-mode push-button switch with variable speed trigger - allows users to easily transition between speed settings and adjust LED brightness, so the tool adapts quickly to different application demands without stopping work.
• Hog ring anvil - provides secure socket retention during use, keeping sockets locked in place under high-torque conditions for safer and more reliable operation.
• BATTERYGUARD shock-absorbing battery-to-tool connection - helps reduce wear and tear on the battery over time, extending the working life of your battery investment (battery sold separately).
• On-tool LED work light - illuminates dark or confined workspaces so users can see fasteners and work surfaces clearly without needing a separate light source.
• Cordless 20V Max Lithium Ion platform - compatible with DeWALT's 20V Max battery system, giving users the flexibility to share batteries across tools in the same platform.

Why This Product

• Built for high-torque professional applications - with 1,400 ft-lbs. of max breakaway torque, this impact wrench is well suited for breaking loose seized or heavily torqued fasteners on pipe flanges, grooved couplings, and anchor bolts - jobs that would stall lesser tools.
• Precision control prevents costly mistakes - PRECISION WRENCH mode actively works to prevent overtightening and run-off, which is especially valuable when working with flanges and couplings where proper torque specification matters for system integrity.
• Cordless convenience without sacrificing power - the 20V Max XR cordless design eliminates cord management on busy job sites while still delivering the torque output typically associated with larger corded or pneumatic impact wrenches.
• Adaptable across multiple work conditions - the 4-mode speed selection, variable speed trigger, and LED work light with adjustable brightness combine to make this tool practical across a broad range of environments, from well-lit shops to dark mechanical spaces.

Frequently Asked Questions

Is a battery or charger included with the DCF900B?

No. The DCF900B is a bare tool, meaning it includes only the impact wrench itself. A compatible 20V Max Lithium Ion battery and charger must be purchased separately.

What is PRECISION WRENCH mode and when should I use it?

PRECISION WRENCH mode is a built-in control feature designed to help prevent overtightening when driving fasteners in forward and to help prevent fastener run-off when removing them in reverse. It is particularly useful in applications such as pipe flanges and grooved couplings where hitting a precise torque level matters.

How many speed modes does the DCF900B have?

The DCF900B features a 4-mode push-button switch that allows users to transition between speed settings. The variable speed trigger provides additional control within each mode. The same switch also allows users to adjust the brightness of the on-tool LED work light.

What types of applications is this impact wrench designed for?

This tool is designed for heavy-duty fastening tasks including large-sized pipe flanges, grooved couplings, wheel lugs, and concrete anchor bolt setting, as well as other applications that require high-torque impact wrench performance. Its 1,030 ft-lbs. of max fastening torque and 1,400 ft-lbs. of max breakaway torque make it suited for demanding professional use.
