• Risk of Tangles or Snags: The power cord can get in the way, especially when working in complex environments with multiple tools or during tasks that require free movement.

Torque Range and Its Importance

The torque of an electric wrench is a key specification that directly influences the tool’s performance. Torque is measured in foot-pounds (ft-lbs) or Newton meters (Nm) and represents the rotational force the wrench can apply to fasteners.

Understanding Torque in Electric Wrenches:

• Low Torque Wrenches: Typically offering around 100-300 ft-lbs of torque, these are ideal for lighter tasks like furniture assembly, small automotive jobs, or basic DIY projects. For example, the Craftsman CMMT14100 falls into this category.
• Medium Torque Wrenches: These wrenches provide 400-700 ft-lbs of torque and are suitable for medium-duty tasks such as working on larger vehicles or moderate construction work. Models like the DeWalt DCF899B are built to handle these types of tasks.
• High Torque Wrenches: High-end models offer torque in the 1,000+ ft-lbs range, designed for heavy-duty work in industrial settings, automotive repairs, and more. The Milwaukee 2767-20 M18 FUEL is a great example of a high-torque wrench designed to handle more challenging jobs.

The higher the torque, the more power the wrench has to loosen or tighten larger, more stubborn fasteners. However, higher torque also requires more control, as excessive force can damage parts, so it’s essential to choose a model with the appropriate torque for the job.

Speed and RPM Considerations

Speed (measured in RPM, or revolutions per minute) is another important feature in selecting an electric wrench. Different jobs require different speeds, so understanding the RPM range can help in choosing the right tool.

• Low Speed (0-1,500 RPM): Ideal for tasks that require controlled tightening or loosening, like assembling furniture, working on electronics, or fine-tuning mechanical components.
• Medium Speed (1,500-2,500 RPM): This is common for general-purpose work, such as repairing light vehicles, tightening nuts on construction machinery, and other everyday tasks.
• High Speed (2,500 RPM and above): High RPM wrenches are designed for high-efficiency tasks that need quick fastening or removal, such as in industrial environments or heavy-duty automotive repair. The Milwaukee 2767-20, for example, offers a speed range that can handle both delicate and high-torque tasks.

Many modern electric wrenches come with multiple speed settings, allowing users to adjust the speed according to the demands of the task at hand. This versatility ensures that the wrench is suitable for a variety of applications.

Battery technology plays a significant role in the performance of cordless electric wrenches. Modern electric wrenches commonly use lithium-ion (Li-ion) batteries due to their lightweight nature, fast charging capabilities, and long-lasting power. Key battery specifications include voltage (V), amp-hour (Ah), and runtime.

• Voltage (V): Higher voltage generally means more power, so a 20V battery typically provides more torque than an 18V battery. However, higher voltage batteries can also add to the tool’s weight.
• Amp-hour (Ah): This refers to how much energy a battery can store. A higher Ah rating indicates a longer runtime before recharging is necessary.
• Runtime: The runtime is influenced by both the battery capacity and the tool’s energy efficiency. Lithium-ion batteries, like the M18 RedLithium used by Milwaukee, provide excellent runtime compared to older technologies like nickel-cadmium (NiCd).
