The Best Cordless Ratchet Option


Cordless ratchets allow you to work on your vehicles or your home without putting in the effort to operate a manual ratchet and without the risk of tripping on an air ratchet’s air hose. These tools use a battery to power the motor, which in turn rotates the head of the ratchet. More than just time-saving, it allows you to work in tight spaces without having to worry about your ratchet handle’s swing clearance.

The best cordless ratchet for your home tool kit will depend on its power output, size, weight, battery, and grip. Many offer safety features that can extend the life of the tool while keeping you safe. Some of the best cordless ratchets are featured in the list below.

What to Consider When Choosing the Best Cordless Ratchet

Before buying a new cordless ratchet, there are important features to consider. These characteristics include size, weight, power output, and battery life.

Size and Weight

Most cordless ratchets are light enough to be used with just one hand. However, even a difference of one or two pounds can increase the likelihood and severity of common hand fatigue symptoms like hand cramps. A lightweight cordless ratchet can help you avoid this common problem.

The ratchet should have a narrow head and a slim body so that it can be comfortably maneuvered around and through obstacles, allowing you to work in tight areas. Keep in mind that the size and weight of a cordless ratchet typically correlates to power output, with smaller models having less power. Cordless ratchets range in weight from just under one pound to three pounds, and most can fit inside a variety of tool boxes and tool belts.


The power of the cordless ratchet motor is measured by the torque output and the speed. Torque refers to the rotational force produced by the cordless ratchet and is measured in foot-pounds (ft-lbs). The average torque of a cordless ratchet ranges from 25 to 50 ft-lbs, with the more powerful models being better suited for automotive work.

The speed of a cordless ratchet is measured in revolutions per minute (rpm), with an average ratchet producing between 250 and 400 rpm. The faster speed allows you to quickly loosen or tighten bolts and fasteners, but it could also cause you to overtighten if you aren’t careful.

Brushed vs. Brushless Motor

Whether a cordless ratchet has a brushed or brushless motor can affect the price and efficiency of the tool.

  • Brushed motors use brushes inside the motor to deliver electrical current to the motor windings. This physical contact causes their efficiency to fall to about 75 to 80 percent when compared to the 85 to 90 percent efficiency of a brushless motor. However, tools with these motors are more affordably priced, making them a good option for casual use.
  • Brushless motors use a type of encoder device to achieve the same result without the wear and tear caused by physical brushes. This extends the life of the motor, increases the overall efficiency, and makes the motor quieter. Tools with brushless motors typically cost more.


The battery life for a cordless ratchet is measured using milliamp-hours (mAh) for small batteries, or amp-hours (Ah) for larger batteries, with 1000 mAh equaling 1 Ah. A one amp-hour (Ah) battery is capable of producing one amp of energy per one hour of time. Alternatively, a 1-Ah battery can produce 10 amps of energy, but can only do so for six minutes.

The average Ah rating for cordless ratchet batteries is between 0.5 Ah and 2.5 Ah. Your battery life needs depend on the availability of electric power for recharging, the average length of use, and the power, torque, and speed requirements of the ratchet. Higher energy output will drain a battery faster.

Comfort and Grip

Just like many other power tools, the grip of the handle on your cordless ratchet is an important aspect to keep in mind. The grip absorbs the impact while you work, which helps to protect your hands and reduce hand fatigue. A grip with a cushioned support is easier on your fingers and muscles, allowing you to firmly grip the cordless ratchet without having to squeeze down on hard metal or plastic.

When you look for a new cordless ratchet, keep in mind that the tool will use a lot of torque to fasten and unfasten nuts and bolts. A handle with a nonslip surface helps you stay in control while you work.


The flexibility of a cordless ratchet refers to its ability to be used in a range of difficult situations. A manual ratchet typically has a long, narrow head and handle, allowing it to fit into tight spaces, such as behind a furnace, or in the cramped confines of a mechanical room. However, once the ratchet is in place you still need enough room to move the handle. If you don’t have the space, the socket won’t turn. To address this issue, you can use a cordless ratchet that has a narrow head. It will be able to fit into similar spaces, and you can use the trigger to power the ratchet head so you won’t have to turn the handle.

For tight locations, a forward-reverse switch is necessary. This will allow you to quickly change the direction that the ratchet will turn without having to remove or adjust the ratchet beforehand. As well, these types of spaces, such as inside a car engine, can be easier to work in using a ratchet with a built-in light.

Drive Size

The drive size of a cordless ratchet refers to the size of the sockets you can use with the ratchet. The most commonly used drive size is ⅜-inch, although a ¼-inch socket is commonly used for smaller motors, like a lawnmower.

  • A ¼-inch drive is the smallest of the two common drive sizes and it’s frequently used for motorcycles, mopeds, lawnmowers, and some HVAC applications. If you have a ⅜-inch cordless ratchet, then it may be beneficial to get a ⅜-inch to ¼-inch adapter. If you are looking for a new tool, then cordless ratchets with a ¼-inch drive size are less expensive.
  • The ⅜-inch drive is commonly used in major automotive repairs for engine work, including tightening spark plugs. These cordless ratchets are normally more powerful than those with a ¼-inch drive because they are intended to work with larger fasteners, but they also may be more expensive.


Before using any power tool you should understand how it works, identify any safety concerns, and learn how to operate any safety features. A cordless ratchet can be built with a variety of safety features including a safety trigger lock, a battery indicator, a forward-reverse switch, and an electric brake.

  • Safety trigger locks prevent you from accidentally pressing the trigger, causing the cordless ratchet to rotate the attached socket. This simple lock keeps you from overtightening your fasteners and prevents the tool from accidentally starting.
  • A battery indicator doesn’t keep you safe in the traditional sense, but it does help you know how much power you have remaining before you need to recharge. This allows you to properly plan for projects instead of trying to figure out how to reattach a fastener when your ratchet has a dead battery.
  • The forward-reverse switch gives you the ability to back off of a fastener so that you don’t overtighten it. This simple switch can help you avoid having to remove your hand from a tight location just to turn the tool around.
  • An electric brake automatically stops the tool from applying force as soon as the trigger is released. If your fasteners absorb the remaining kinetic energy, they can crack and break.

FAQs About Cordless Ratchets

Continue reading below to find the answers to some of the most commonly asked questions about cordless ratchets.

Q. How does a cordless ratchet work?

A cordless ratchet uses a battery to drive a motor which in turn rotates the ratchet head. This automatic function is used with a socket to remove nuts and bolts without having to use any manual force beyond pushing the power trigger.

Q. How do you use a cordless ratchet?

A cordless ratchet is used by attaching a compatible socket to the ratchet head and lining it up with the nut or bolt you want to tighten or loosen. Once the socket is sitting securely over the nut or bolt head you can press the power trigger to begin applying pressure to the socket, forcing the nut or bolt to turn. Typically you will have a variable speed trigger that allows you to control the speed without designated power levels.

Q. How long does a cordless ratchet last?

On average, a cordless ratchet will last five to 10 years with regular use and proper care.
