The Ultimate Guide To Electrical Impact Wrench Ft-Lb Ratings

Electric impact wrenches are power tools that can tighten and loosen bolts, nuts, and screws. They are available in corded and cordless variants. Cordless impact wrenches are more portable than their pneumatic cousins as they do not need to be connected to an air compressor to function. They are also more comfortable to use since the concussive blows are smoothly transferred to the fastener rather than the user's hand, wrist, or arm.

Characteristics of Electrical Impact Wrenches:

Electric impact wrenches with brushless motors

One example of a brushless electric impact wrench is the DEWALT 20V MAX XR, which delivers up to 2,400 IPM and offers 700 lb-ft and 1,200 lb-ft of breakaway torque. It features a bright LED work light, an ergonomic grip, a 1/2 inch hog ring anvil, and multispeed control.

Another option is the Milwaukee 2967-20 M18, which can loosen the most stubborn bolts with its brushless motor, providing up to 1,100 lb-ft of fastening torque and 1,600 lb-ft of breakaway torque. This wrench also includes three LEDs surrounding the anvil for better lighting and a four-mode drive control for greater precision.

The Makita XWT08Z 18V LXT is another brushless electric impact wrench ideal for automotive and industrial tasks. Its brushless motor extends battery life, providing up to 50% longer runtime per charge. It offers three power modes and a 1/2 inch anvil with a friction ring for quick changes.

When choosing an electric impact wrench with a brushless motor, consider the torque range, drive size, weight, ergonomics, and additional features such as LED lights and speed settings. These factors will ensure you select the right tool for your specific needs, whether you're a professional mechanic or a DIY enthusiast.

Impact wrenches with multiple speed settings

Most impact wrenches have three or four speed settings, allowing users to reduce the revolutions per minute (RPM) and torque to prevent overtightening fasteners or spinning off lug nuts. Some impact wrenches have automatic modes that slow down the wrench after it has broken off a bolt, preventing it from spinning off. Others have controls that allow users to dial in lower torques to simulate hand or wrench tightening.

The Milwaukee M18 Fuel 1/2-Inch Impact Wrench, for example, has four modes, three different speeds, and a bolt removal mode, making it easy to set the speed and torque for the job at hand. The DeWalt Atomic 20V Max Compact 1/2-Inch Impact Wrench also has four speed settings and a bolt removal and fastening mode that prevents runoff and overtightening.

The number of speed settings can be a key factor in choosing an impact wrench, as it allows for greater control over the tool's performance. Higher speeds and torque settings are ideal for heavy-duty tasks, such as breaking free rusted bolts or tightening bolts in construction projects, while lower settings are suitable for lighter-duty applications, such as car repairs or furniture assembly.

When selecting an impact wrench, it is important to consider the torque, drive size, and power source, in addition to the speed settings. The torque determines the force applied when tightening or loosening a bolt or nut, and should be chosen based on the specific project requirements. Drive size refers to the square drive socket installed in the impact wrench, with common sizes being 1/2-inch, 3/8-inch, and 3/4-inch. Cordless impact wrenches offer unmatched portability and convenience, while corded impact wrenches deliver higher torque output and continuous operation.

Impact wrenches with multiple modes

The Milwaukee M18 Fuel ½-Inch Impact Wrench, the best overall impact wrench according to Popular Mechanics, has four modes, three different speeds, and a bolt removal mode. This bolt removal mode is designed to slow down the speed and torque once a nut or bolt breaks loose, preventing it from spinning off.

The DeWalt Atomic 20V Max Compact ½-Inch Impact Wrench, the best compact impact wrench, has a mode for bolt removal and fastening that prevents runoff and overtightening, along with four speed settings.

The Ingersoll Rand ½-Inch High-Torque 20V Impact Wrench has a large, visible mode selector with four modes: hand tight, wrench tight, half power, and full power. This makes it easy to see what mode the wrench is in and select a different mode.

The Milwaukee M18 Fuel 3/8-Inch Mid-Torque Impact Wrench has four mode settings, with the fourth mode being the most notable. This "drive control" mode limits torque to 35 foot-pounds when driving, preventing overtightening, and starts at full torque when removing a fastener, backing off the RPM when the fastener breaks loose to prevent spinning it off at full speed.

The Flex ½-Inch Mid-Torque 24V Impact Wrench has an auto-stop mode that prevents overtightening, along with three other mode settings that limit RPMs to 400, 1,600, or 1,200.

The Ridgid 18V SubCompact ½-Inch Impact Wrench has a bolt-tightening mode that prevents overtightening by shutting down at about 20 foot-pounds.

Impact wrenches with torque below 500 ft-lbs

If you're looking for an impact wrench with high power in a compact design, then look no further than the range of options with torque below 500 ft-lbs. These tools are ideal for delivering the right amount of power without taking up too much space and are available in manual, corded, and battery-powered options.
