How to pick the right one
Common questions
What is the difference between an impact driver and an impact wrench?
Impact drivers typically have a 1/4 inch hex chuck and are for driving screws. Impact wrenches have a 1/2 inch square drive and are for removing and tightening nuts and bolts.
Can I use a cordless impact wrench to remove lug nuts?
Yes, most 1/2 inch impact wrenches can remove lug nuts. Ensure the torque rating is sufficient for your vehicle. Usually, over 300 ft-lbs is enough for cars, but trucks may need more.
Do I need a high-torque impact wrench for DIY projects?
For light DIY tasks, a compact or mid-torque model is often enough. High-torque wrenches are heavier and more expensive. Assess the types of fasteners you will encounter.
What does nut-busting torque mean?
Nut-busting torque is the maximum torque the tool can apply to loosen a stuck fastener. It is usually higher than fastening torque. It is measured in foot-pounds.
Are brushless motors worth the extra cost?
Yes, brushless motors are more efficient, produce less heat, and last longer. They also provide more runtime per battery charge. Many users find them worth the investment.
Can I use an impact wrench for tightening?
You can, but you risk over-tightening. Use a torque stick or a lower speed setting. Many wrenches have a ‘tightening’ mode. Always follow torque specifications.
What size drive should I choose?
1/2 inch is the most common and offers a wide range of sockets. 3/8 inch is lighter and good for smaller fasteners, but torque is lower. 3/4 inch is for heavy industrial use.
How long does a battery last on a cordless impact wrench?
Battery life depends on the amp-hour rating and the load. A 5Ah battery can last for dozens of lug nuts on a car. High torque tasks drain faster. It is good to have a spare battery.
Are cordless impact wrenches as powerful as air tools?
Modern cordless models often match or exceed pneumatic tools. They offer convenience without a compressor. High-end models like the Milwaukee 2767 can compete with air wrenches.
What is the best way to store a cordless impact wrench?
Store it in a dry place. Keep the battery at a partial charge if storing for a long time. Use the included case or a tool bag to protect it from dust and drops.
Final word
For most people, the Milwaukee 2767-20 is the best cordless impact wrench. It offers the best balance of power, size, and reliability. If you are on a budget, the Porter-Cable is a good starter. For professionals who need maximum torque, the Ingersoll Rand is a solid choice.
