A cordless or pneumatic power tool designed to deliver high-torque output with minimal rotational kickback to the user is an essential piece of equipment for many professionals. This type of tool utilizes a hammering action to drive screws and fasteners quickly and efficiently, making it ideal for tasks involving heavy-duty materials or repetitive fastening operations. An example application would be automotive repair where it is frequently used to remove and install lug nuts.
The benefits of such tools include increased productivity due to faster fastening, reduced user fatigue thanks to lower vibration and torque reaction, and the versatility offered by various sizes and power options. This technology has evolved significantly over time, from early manual impact drivers to the sophisticated cordless and pneumatic models available today. This evolution has mirrored the increasing demands of professional trades and the constant drive for improved efficiency and ergonomics.
