Questions worth asking
What is the difference between fastening torque and breakaway torque?
Fastening torque is the amount of rotational force the wrench can apply to tighten a fastener. Breakaway torque, also called nut-busting torque, is the maximum force it can exert to loosen a tightly fastened bolt or nut. Breakaway torque is typically higher than fastening torque.
Can a 20V impact wrench remove lug nuts?
Yes, most 20V impact wrenches with at least 300 ft-lbs of torque can remove standard car lug nuts. For trucks or large SUVs with higher torque specs, you may need a high-torque model with 500 ft-lbs or more.
Is a brushless motor better than a brushed motor?
Yes, brushless motors are more efficient, providing more power and longer battery life. They are also more durable because there are no brushes to wear out. Most modern impact wrenches feature brushless motors, especially higher-end models.
Do I need a battery and charger if I already have a drill from the same brand?
No, if you already have batteries from the same brand and voltage, you can purchase the bare tool version, which does not include a battery or charger. This can save you money if you already own compatible batteries.
What size socket drive should I choose?
The most common sizes are 1/2-inch and 3/8-inch. A 1/2-inch drive is standard for automotive work and can handle higher torque. A 3/8-inch drive is smaller and better for tight spaces but may not have as much torque. For heavy-duty applications, 1/2-inch is recommended.
How long does a battery last on a full charge?
Battery life varies depending on the battery capacity and the intensity of use. A typical 5.0 Ah battery can last for dozens of lug nut removals. Higher capacity batteries, such as 8.0 Ah or 12.0 Ah, will provide longer run times but add weight.
Can an impact wrench be used to tighten bolts?
Yes, but you must be careful not to over-tighten, which can strip threads or damage components. Many impact wrenches have variable speed triggers and multiple speed settings. Using a torque wrench for final tightening is recommended for critical fasteners.
What is the advantage of a compact impact wrench over a full-size one?
Compact impact wrenches are lighter, shorter, and easier to maneuver in tight spaces. They are ideal for engine work or under-dash repairs. However, they generally produce less torque than full-size models, so they may not be suitable for the toughest jobs.
Are impact wrenches compatible with standard sockets?
No, you should use impact-rated sockets. Standard sockets are made of harder material and can shatter under the high torque and vibration of an impact wrench. Impact sockets are thicker and more durable, designed to withstand the stress.
How much should I spend on a 20V impact wrench?
Prices range from around current price to current price or more for bare tools. Budget models are suitable for occasional DIY use, while professional-grade models with high torque and advanced features cost more. Consider your frequency of use and the types of jobs you’ll tackle.
