The verdictOur take

The DCF900 is DeWalt's established 1/2in high-torque wrench: 1,396Nm fastening and 1,898Nm breakaway at 2.9kg bare. That is enough for most seized wheel nuts and plant fixings. The newer DCF961 adds more torque for a little more weight; the DCF891 is lighter if you rarely need this much.
