Tool Companies Adopt New Torque Ratings

摘要

In the 30 or so years that power drills and drill/drivers have been on the market, toolmakers have been competing with each other over torque ratings, or the measure of the tools' turning force. But because these ratings typically come from in-house or third-party laboratory testing, the equipment and methods vary, and so do the results. Often, the publicized torque ratings are peak measurements (the initial half-second burst of energy when the trigger is pulled) rather than sustained torque, which is a more realistic representation of the tool's performance during normal use.
