Impact wrench is designed for tightening and loosening various types of bolts, nuts, and screws. It employs powerful rotational force to reduce the time for fixing the bolt or the screw firmly. Along with the power, these tools have to be extremely comfortable for the technicians to do their work efficiently.
Full-size impact has a larger, longer tool head, with higher torque; however, it may not fit in the spaces where it is to be used. Here Compact or subcompact impact wrench with shorter, less bulky, tool head can fit into tight spaces better. Because they are smaller, they don’t have the high torque like the larger models. Torque is the most important representation of power for an impact wrench, indicates the tool’s ability to drive the bolt or loosen the nuts.
Most drill/drivers have enough power to drive the thick bolt and remove rusted and fixed nuts. Impacts per minute (IPM) increase as revolutions per minute (RPM) increase. High RPM help drive nuts or bolts faster, Most of these three or four settings that control the speed and RPM to avoid over tightening fasteners or avoiding slip and skids that can cause accidents.
