Torque and speed

The torque and speed of an impact ratchet wrench are two of the most important factors to consider when choosing the right tool for the job. Torque refers to the rotational force produced by the wrench, while speed refers to how fast the wrench can rotate. Both of these factors will determine the effectiveness and efficiency of the tool in different applications.

Torque

The torque of an impact ratchet wrench is a measure of the rotational force it can apply to a fastener. It is typically measured in foot-pounds (ft-lbs) or Newton metres (Nm). The higher the torque rating, the more force the wrench can apply, making it suitable for larger and more stubborn nuts and bolts.

For example, a heavy-duty air impact wrench can deliver more than 500 ft-lbs of torque, which is approximately 678 Nm. On the other hand, air ratchets typically have lower torque ratings of around 60 to 130 ft-lbs. This makes them more suitable for smaller nuts and bolts.

Speed

The speed of an impact ratchet wrench refers to how fast it can rotate, and it is typically measured in revolutions per minute (RPM). A faster speed allows users to loosen or tighten bolts and fasteners more quickly. However, it is important to be careful when using a high-speed wrench to avoid overtightening.

The speed of impact ratchet wrenches can vary significantly depending on the model and power source. For example, the free spin speed of impact wrenches can range from 2,000 RPM to more than 14,000 RPM. Cordless ratchet wrenches, on the other hand, typically have lower speeds, ranging from 250 to 400 RPM.

When choosing an impact ratchet wrench, it is important to consider the torque and speed that is suitable for the specific application. For heavy-duty applications or larger fasteners, a higher torque and speed may be required. For smaller nuts and bolts, a lower torque and speed may be sufficient, and a compact and lightweight wrench may be easier to manoeuvre in tight spaces.

Battery life

When it comes to battery life, there are a few things to consider when choosing a cordless ratchet wrench. Firstly, the type of battery and its capacity will impact how long the wrench can be used before needing to be recharged. Common battery types include lithium-ion, nickel-cadmium, and nickel-metal hydride. The capacity of the battery is typically measured in ampere-hours (Ah) or milliampere-hours (mAh), with a higher number indicating a higher capacity and longer runtime.

Additionally, the power output of the wrench will affect battery life. A wrench with a higher torque and speed will generally consume more power and drain the battery faster. Other factors that can impact battery life include the efficiency of the motor, with brushless motors typically being more efficient than brushed motors, and the type of work being performed, as well as the temperature and other environmental conditions.

To maximize battery life, it is recommended to use a wrench with a brushless motor, as they are more efficient and produce less heat, which can extend runtime. Additionally, choosing a wrench with a variable speed trigger can help conserve battery power by allowing the user to adjust the speed according to the task at hand. Proper maintenance and care of the battery, such as regular charging and storage, can also help prolong its life and maintain its capacity.
