An impact wrench is a powerful tool designed to make loosening and tightening bolts and nuts much easier. It uses a combination of torque and rapid bursts of rotational force to drive fasteners quickly. This makes it especially useful in automotive repair, construction, and other heavy-duty applications where high torque is needed. These tools come in various types, including electric and pneumatic versions. An electric impact wrench is often used in home garages, while a pneumatic impact wrench is commonly found in professional settings, like auto shops. Both types help save time and effort, making tasks more efficient.
