Questions worth asking
What is the typical torque needed for removing lug nuts?
Most lug nuts require about 80 to 100 ft-lbs to tighten, but they can be overtorqued. To remove them, you need an impact wrench with at least 300 ft-lbs of torque. Many heavy duty models provide 500 ft-lbs or more to easily break them free.
Can I use these tools to work on my car or truck?
Yes, these sets are designed for automotive work. They can handle suspension bolts, engine mounts, and brake calipers. For heavy truck work, you may need higher torque models like the Milwaukee M18 FUEL.
Are brushless motors worth the extra cost?

An impact wrench has a square drive that accepts sockets, used for larger fasteners like lug nuts. An impact driver has a hex chuck that accepts bits, used for screws. Some kits include both for versatility.
Do these kits come with a case?
Many kits include a hard case or bag. The DEWALT ToughSystem includes a very durable case. Others like the Milwaukee may not always include one. Check the product description.
