DEWALT vs CRAFTSMAN Impact Wrenches
Max Torque Output
The DEWALT DCF900B delivers significantly higher torque than the CRAFTSMAN CMCF940M1. DEWALT provides 1030 ft-lbs of max fastening torque and 1400 ft-lbs of max breakaway torque. This makes it suitable for demanding tasks like large pipe flanges, wheel lugs, and concrete anchor bolts. In contrast, the CRAFTSMAN offers 700 ft-lbs of max tightening torque and 1000 ft-lbs of breakaway torque. While sufficient for many automotive and general fastening applications, DEWALT has the clear advantage for high-resistance fasteners.
Included Battery and Charger
Package contents differ substantially between the two kits. The CRAFTSMAN CMCF940M1 is sold as a complete kit with both a battery and a charger included. This means you can start working immediately after unboxing. The DEWALT DCF900B is listed as a bare tool, meaning the battery is sold separately. If you already own compatible 20V MAX batteries, DEWALT is cost-effective. However, for new users, CRAFTSMAN provides a more complete starting solution with its included power source.
Speed Settings and Control
Both tools offer variable speed triggers for fine control, but DEWALT provides more distinct speed modes. The DEWALT DCF900B features four-mode speed settings, allowing for greater precision across a variety of applications. This helps prevent overtightening and fastener run-off. The CRAFTSMAN CMCF940M1 offers three-speed settings. While both allow for adjustable control, DEWALT’s additional mode gives you more granular options for different fastening tasks, providing a slight edge in versatility.
Weight and Dimensions
Portability and balance are important for overhead or tight-space work. The DEWALT DCF900B weighs 6.4 pounds and measures 9.94 inches in length. The CRAFTSMAN CMCF940M1 dimensions are listed as 12.2 inches in length and 5.87 inches in width, but its weight is not specified in the data. Based on available data, DEWALT has a more compact length and a specified weight. Without CRAFTSMAN’s weight data, DEWALT appears more manageable for extended use, though direct comparison is limited.
Motor and Power Source
Both impact wrenches utilize brushless motors and run on 20V cordless battery platforms. DEWALT uses its 20V MAX system, while CRAFTSMAN uses its V20 system. Both motors offer better runtime and efficiency compared to brushed alternatives. The power source is identical in category: cordless battery. Since both are brushless and 20V, neither holds a technical advantage in motor technology or voltage class. They are equivalent in their core power delivery method.
