A car mechanic or an owner knows that changing a tire is the utmost troublesome task. Sometimes, the bolts and nuts are positioned at a very awkward angle, and fitting a wrench in there for fastening or loosening becomes just impossible.

Types of Impact Wrench?

Impact wrenches are mainly of four kinds:

  1. Electric(Corded or Cordless mechanism of electricity),
  2. Pneumatic(mechanism of compressed air),
  3. Hydraulic (mechanism of fluid), and
  4. Hybrid (mechanism of impact-wrench conversion).

What size air compressor does need with an impact wrench for lug nuts?

The average needed size for an air compressor is a 4-5 CFM @90 PSI for a 1/2-inch impact wrench. If the impact wrench has a 1-inch drive, it will need a 10 CFM @90 PSI. For a 1/2-inch drive, 4 CFM @90 PSI, while 3/8-inch requires a 3CFM @90 PSI.

Will a Cordless Impact Wrench Remove Lug Nuts?

A cordless 18V impact wrench can loosen lug nuts. Technically, you would require a hex shaft to square drive adapter to help attach the tool to the lug nut socket. However, impact drivers may not be helpful if the nut is rusted or over-tightened.

You may also want to wear safety accessories, such as safety glasses. Additionally, tie your hair back if you have long tresses, remove hanging jewelry pieces, and pull back your sleeves. Clear your workspace of any clutter that can cause slips, trips, or falls.
