What is a Pneumatic Impact Wrench?
A pneumatic impact wrench is a power tool that utilizes compressed air to generate high torque output. They are typically used in automotive repair shops, construction sites, and other heavy-duty environments. These wrenches are capable of loosening or tightening bolts and nuts with ease, making them invaluable for any professional toolkit.
How They Work
Pneumatic impact wrenches operate using an internal mechanism that delivers rapid bursts of torque. When the trigger is pulled, compressed air flows through the tool, engaging a hammer mechanism that strikes an anvil, producing high torque. This process allows the wrench to work quickly and efficiently, reducing the amount of time spent on repetitive tasks.
