What To Know Before Buying Cordless Impact Wrenches

Cordless impact wrenches are extremely useful tools for construction, mechanical, or landscaping projects, but finding the best option for you will depend on several factors. You should consider the wrench’s battery, ergonomics, power level, and size before purchasing.

Battery

The battery level of cordless impact wrenches is measured in voltage, while the battery size is measured in Ah. Typical power levels include 12 volts and 18 volts for small- and medium-sized tools and 20 volts and 24 volts for larger impact wrenches. Tools with a higher Ah will typically run for a longer charge. Ah levels can range anywhere from 1.5 to 6 depending on the make and model. 

Ergonomics 

Impact wrenches can be challenging to use and maneuver if you’re not used to them. However, most modern tools have features that make them easier to operate. Look for cordless wrenches with a comfortable handle to ensure the tool won’t cause hand or wrist pain. Additionally, many cordless impact wrenches come with ring lights and vibration control to reduce common pain points. Models with a lightweight design will usually be easier to handle than heavier models. 

Power Level and Speed

The higher the power level, the more efficiently you can get through the job. Powerful tools can run at a higher price point, so it’s important to know what job you’ll be performing and if you need maximum torque and RPM. 

The power level of a cordless impact wrench is determined by its torque, which high-level models are capable of upwards of 3,000 pounds, and compact models sometimes offer as low as 100 pounds. The speed is measured by IPM (impacts per minute) and RPM, which indicates how quickly it can drive nuts and bolts. 

Size

Most cordless impact wrenches are 1/2-inch drive models that accept 1/2-inch sockets, but smaller (usually 3/8-inches) and larger (1/4-inches) models are also available. Cordless impact wrenches are typically full compact or subcompact, with most models being full compact unless labeled otherwise. Full-sized models have longer tool heads that can produce higher torque. However, a sub-compact model may be better for fitting into tight spaces. Sub-compact wrenches will typically be lighter and more maneuverable than full-compact tools. 

Common Uses for Impact Wrenches

Many associate impact wrenches with professional construction or automotive projects, but they can also be extremely useful to have for less-intensive household jobs. Here are some ways you can utilize a battery-powered impact wrench to help you get things done around your home:

• Assembling furniture
• Changing tires
• Checking brakes
• Crafting metal when welding
• Installing cabinets
• Installing shock absorbers
• Mounting TVs
• Putting together a swing set
• Replacing bike pedals or handlebars
• Securing rail components on a deck
• Swapping lawn mower blades
• Tightening and loosening bolts

FAQ About Cordless Impact Wrenches

What’s the difference between an impact wrench and an impact driver?

Impact wrenches can deliver more torque than an impact driver, making them more suitable for use on heavy-duty projects such as removing lug nuts or large bolts. Additionally, impact wrenches usually have larger chucks ranging up to 1 inch, while impact drivers typically have 1/4-inch chucks.

What are the advantages of a cordless wrench vs. an air-powered wrench?

Cordless impact wrenches provide more maneuverability and convenience than corded wrenches or wrenches that run on compressed air. Air-powered (also called pneumatic) models may be less expensive, but they require an air compressor setup to work properly. 

How do you maintain a cordless impact wrench?

Cordless impact wrenches need routine maintenance to ensure they continue to work properly. Cleaning the tool regularly, lubricating it after each use, and properly charging and storing the battery are some basic steps you can take to keep your wrench working properly and extend its shelf life. 

What safety precautions are needed when using an impact wrench?

You should wear proper safety equipment, such as hearing protection and safety glasses, when using an impact wrench. You should also keep the work area free from hazards and ensure the area is well-lit before operating the device. Never use an impact driver if intoxicated, overly tired, or on medications.
