How it was tested
- loosening torque measured via clamp load on a 3/4 inch left-hand threaded bolt (50 ft-lb pretorque baseline, 4,273 lb clamp load), converted to ft-lb, plus subjective hand-vibration observation
- driving a 1/2 inch by 10 inch lag bolt for 30 seconds, measuring inches of progress and sound level 24 inches from the tool
- driving three 5 inch lag bolts back to back in wood, timed
- extracting the same three lag bolts, timed
- weight, physical compact length, and idle sound level comparison across all 13 tools
