The efficiency you get out of an electric tapping arm is unmatched. Forward and reverse with torque and clutch settings. These aren’t cheap but if you value your time and do any amount of metalwork that involves tapping holes you’ll buy one. Being able to tap multiple parts or multiple holes in the same part quickly and accurately is such a time saver! I have a whole video about this on my YouTube channel if you want to learn more.
