How is a torque rating generated?
The process for which a torque rating is generated is a standard procedure in the industry. A drill is mounted into a rig (piece of testing equipment). The chuck of the drill is locked down onto a fixed spindle (spindle does not rotate). The drill is fully powered. The spindle, which is fixed, measures the force at which the drill is trying to turn it. The torque rating is a measurement of the amount of force that is being applied to the spindle at 0 RPM.
