What is an impact wrench?

An impact wrench or gun/air wrench is a power tool to tighten or loosen bolts, lug nuts, and stuck or rusted fasteners. The impact wrench is your best choice if you have construction, automotive repair, and other mechanical applications with high torque requirements.

The tool provides a higher torque power compared to regular power drivers. Impact wrenches achieve this high power through an internal hammering mechanism that transfers kinetic energy onto the output shaft. The tool can deliver a string rotational force or torque in short bursts.

Besides, impact wrenches use a motor to generate rotational energy, which is then transferred to the output shaft. The impact wrench is integrated with a mechanism to deliver the torque in rapid, repeated bursts known as “impacts.” It is from these impacts that the tool derives its name.

Impact wrenches can be corded or cordless. The cordless impact wrenches operate without a direct connection to an air compressor. Instead, they are powered by rechargeable batteries. As a result, the cordless impact wrench allows you to move freely without being restricted by hoses or cords, making them convenient for different applications in outdoor or remote settings.

The cordless ½ cordless impact wrenches have specific components that increase efficiency. The tool has an embedded motor to generate the rotational energy that delivers the torque for its operation. Besides, the cordless impact wrench uses rechargeable batteries as the primary power source. The batteries have capacities that vary based on the model and brand. The higher the battery capacity, the longer the run time. That is, a battery capacity of 20V will provide more power and a longer run time than a 12V battery.

Moreover, like other impact wrenches, the cordless type has an impact mechanism to convert rotational energy into short, powerful bursts of torque.

Types of impact wrenches

There are three impact wrenches types based on the power used to produce torque. These are air-powered(pneumatic), corded, and cordless electric-powered wrenches.

  • Air-Powered Wrenches

Air-powered impact wrenches are the most traditional since they were the first to be designed. As their name suggests, they use compressed air to power their motors.

The main advantage of air impact wrenches is that you can always use them even without power. They are often smaller than the other impact wrenches, making them perfect for use in tight, unreachable spaces.

The main disadvantage of pneumatic impact wrenches is the lack of torque control. Usually, they don’t come with power adjustment mechanisms, which makes them difficult to use in situations that require less power.

They often deliver excess torque, which damages the nuts and bolts.

  • Corded-electric powered wrenches

These wrenches are powered by connecting them directly to an electrical source (usually a socket) using an electrical cord. They are quite rare as manufacturers are leaning more towards cordless ones.

Corded electric wrenches have longer bodies than pneumatic ones because of the extra length added by an electric motor that produces the torque.

You can use corded wrenches non-stop where there is a constant power supply. They come with power regulation components that make them handy in tasks that require low torque. Their main disadvantage is that they are useless in remote locations without electricity.

  • Cordless-electric powered wrenches

Batteries power the motors of the best 1/2 cordless impact wrench. Most use rechargeable lithium-ion (Li-ion) batteries with 18-28 volts depending on the tool’s model.

The main advantage of these power wrenches is that they are portable. Since they don’t require an external power source, they are ideal for on-the-road repairs where there is no available electrical outlet.

On the downside, they are less powerful than corded and pneumatic impact wrenches. The batteries cannot store enough power to produce enough torque for tough tasks.

Also, the cells tend to run out, causing constant work interruptions to charge or replace them.

Why choose impact wrenches?

The best 1/2 cordless impact wrench is specially designed to tighten and loosen various hexhead bolts, nuts, and lag screws. They use rotational force (torque) and short-burst concussive blows (impacts) to deliver unmatched power.

For instance, most cordless drills/drivers produce about 50 ft-lbs of torque, and the standard impact driver can deliver about 125 ft-lbs.

On the other hand, cordless impact wrenches can effortlessly produce torque outputs of over 250 ft-lbs, which is more than enough force to fasten the fattest lugs and loosen stuck and rusty nuts.

All the power held by an impact wrench won’t be beneficial if you have no control over the tool.

Luckily, these power tools are very comfortable because the impacts smoothly transfer most of the torque directly to the fastener instead of your hand, wrist, or arm. This way, the twisting motion (reactionary torque) that you feel when using an electric drill is nearly phased out when using the impact wrench; hence, the best choice.

Best 1/2 Cordless Impact Wrench Buyers’ Guide of 2023

What to Consider When Choosing the best 1/2 Cordless Impact Wrench

  • Battery Voltage/Capacity

The battery power is imperative before you decide on the best ½ cordless impact wrench you want to buy. Cordless tools run on rechargeable batteries; the higher the battery capacities, the longer the runtime.

High-voltage batteries deliver more power than low-voltage batteries. However, the units with a high battery capacity may be heavier than low-voltage units.

When choosing a unit, consider the intended usage and how long you need the tool to operate on a single charge. If you have time-consuming projects such as working in a construction plant, consider a tool with a battery with a higher ampere-hour (Ah) rating to provide longer runtimes. However, if you only need to work on small projects around your home, you can choose models with a battery voltage of 12V. Such units will have a lower Ah.

Moreover, while deciding on the battery capacity, ensure you have also considered the battery type. The two common battery types used in cordless tools are nickel-cadmium (NiCd) and Lithium-ion (Li-ion) batteries.

Choose the best ½ cordless impact wrench model with lithium-ion batteries as they are lighter, have no memory effect, and can hold a charge for longer, providing a longer run time. Generally, lithium-ion batteries also offer better performance than NiCd. Hence, choose the impact wrenches with Li-ion batteries over the NiCd if you want to work on large projects or handle nuts and bolts with the greatest resistance.

  • Grip

Cordless impact wrenches have two distinct body styles: inline and pistol grip. The inline-style wrench looks like a large screwdriver, with a grip behind the hammer and anvil, while a pistol-grip wrench looks like a handgun with the grip resting underneath the motor.

Inline wrenches are lean and work best in spaces where a pistol-type wrench won’t fit. On the other hand, Pistol-style wrenches are bulkier, but their grip style is more ergonomic to prevent work-related strains. Because of this, you can work for extended periods without feeling fatigued.

Some models have side handles that allow you to use your weight for better leverage to maintain a proper working angle. So, if your task does not require the particular fit of an inline wrench, the pistol grip wrench would be a perfect choice.

  • Durability

Choosing a durable impact wrench requires careful research and consideration. Impact wrench tools can be put to numerous applications that vary in intensity and resistance. When selecting the best impact wrench, choose a model with elements such as construction material and brand reputation.

For instance, you should look for impact wrenches from robust materials like high-grade steel, aluminum, or composite materials. The models should have sturdy housing and well-protected internal components to withstand rough usage and impacts better.

Thus, look for tools with design enhancements that help prevent damage caused by drops and tool impact. These could be all-metal construction for the gear housing or premium plastic over-molds.

Also, before you make the purchase decision, research reputable brands and models known for producing high-quality and durable power tools. You can check this depending on the customer reviews and ratings on the major commercial stores such as Amazon to determine their performance and reliability.

Furthermore, consider the Ingress Protection (IP) ratings for the reliability-associated issues. For instance, if you purchase your impact wrench outdoors or in challenging environments, first check if it has an IP. An impact wrench with a higher IP offers better protection against dust and water, making your tool more durable in adverse weather conditions.

  • Torque

Torque refers to the force that causes rotation (τ = F × r). The torque power of an impact wrench is the most crucial feature to consider before deciding to purchase. The best cordless 1/2 impact wrenches on the market have multiple torque settings, making them more versatile than those with only one torque setting.

The torque in an impact wrench represents a rotational force that directly translates to its power and performance. A higher torque implies high rotational force and shows that your cordless impact wrench can handle more demanding tasks like effortlessly removing tight bolts or lug nuts.

The high torque is ideal if you work on heavy machinery, construction projects, or automotive repairs, as it will ensure an effective and efficient result.

Besides, an impact wrench with a high torque can be used in various applications. You can use the tool for both light and heavy-duty tasks or applications, providing greater versatility and eliminating the need for multiple tools.

Also, if you are working on rusted or over-torqued bolts, you would want a significant torque to overcome the resistance and complete the job. An impact wrench with higher torque ratings is built to withstand more challenging conditions. The internal components of high torque impact wrenches are often designed to handle the enhanced stress, making them more durable and long-lasting.

  • Impact per Minute (IPM) and Revolutions per Minute (RPM)

The IPM and RPM determine a cordless impact wrench’s loosening and fastening capabilities. Often, the higher the RPM and IPM values, the higher the ability of the tool to loosen or fasten the nuts or bolts, hence the faster completion of tasks.

The IPM describes the number of hammer strikes or impacts the impact wrench delivers per minute. IPM determines how fast the tool will be loosened or driven. A tool with a higher IPM implies faster operation and enhanced productivity.

Besides, the cordless impact wrenches with higher IPM values are ideal for heavy-duty applications and tasks where speed is crucial. For example, working on an automotive repair or construction project, you will need a higher IPM to tighten or loosen the bolts or nuts. Generally, cordless impact wrenches with IPM values ranging from 2000 to 3500 will be appropriate and ideal for most applications.

On the other hand, revolutions per minute (RPM) describes the number of rotations the wrench’s motor makes in one minute without delivering impact blows. The RPM is necessary to control speed and offer smooth operation when driving fasteners. A higher RPM is crucial for fast starting and positioning the fastener, especially since impact wrenches require precision and control during the initial phase. However, impact wrenches significantly depend on the IPM to deliver fastening and loosening power.

The RPM for the cordless impact wrenches can range from 0 to 500 based on a given model. However, for the impact wrench, the IPM value is not a crucial selection factor as with the IPM.

Nevertheless, when choosing the best ½ cordless impact wrench, go for an IPM value between 2000 and 3500 and RPM values between 0 and 500.

  • Brushless Motor 

Impact wrenches can use brushless or brushed motors. For cordless impact wrenches, brushless motors are the most efficient. Unlike brushed motors, brushless motors eliminate friction and voltage drop. Therefore, impact wrenches with brushless motors will consume less power, preserving battery life and enhancing runtime. The brushless motors produce less heat and require minimal maintenance as the lack of friction reduces wear and tear, offering longer life to the tool.

Besides, the brushless motor produces more power with less weight than the brushed type, hence an increased power-to-weight ratio. Thus, when choosing a cordless impact wrench, go for one with brushless motors, compact, lightweight, and easier to handle.

The brushless motors contribute to a higher efficiency and power output, adding to the tool’s performance. With high-performance efficiency, you will surely realize better performance and faster work completion, making them ideal for heavy-duty tasks.

Furthermore, with brushless motors, there is reduced maintenance. Unlike brushed motors, prone to wear and tear, brushless motors lessen the need for frequent maintenance and replacement practices, saving you both money and time in the long run.

  • Size and Weight

A cordless impact wrench’s size and weight are instrumental factors when making a purchase decision, especially when using the tool for a long time. If you will be using the tool for a long time, choose a compact and lightweight model since it will be easy to maneuver and less tiring.

The torque requirements determine the size and weight of the cordless impact wrench you purchase. You may consider the maximum torque output required for your different tasks. For the different applications you will put the tool to, consider one that will require the maximum torque and use this value to determine the tool you will buy.

Generally, higher torque is helpful for heavy-duty applications, while lower torque models will suffice for lighter tasks. Consequently, tools with high torque are always heavy duty, hence bigger in size and weight and vice-versa.

  • Variable Speed Settings

If you want to work on different projects or materials, you want to choose a tool with variable speed settings. A cordless impact wrench with variable speed settings provides versatility, allowing  adjustment of the tool’s speed and torque output based on the task you want to execute. You can use the same tool for many applications, from heavy-duty projects requiring high torque output to more delicate tasks demanding precision. These tasks will require differential speed settings to achieve your desired results.

Besides, with the variable speed settings, you have maximum control of your projects. The different fastening or loosening tasks may need varying levels of control. You can use the variable speed settings to tailor the impact of the wrench’s speed to match the requirements of every job. Lower speeds are vital for initial positioning and gradual tightening; if you need rapid loosening and driving, you will need a higher speed. All this you can get by having a model with variable speed settings.

Mainly, variable speed settings are crucial when working with softwood, delicate materials, or hard metal. You can change the speed of your impact wrench depending on the material you are working on to avoid damaging the material or fasteners. For instance, soft materials will require low speed, while hard materials like metals may require high-speed settings.
