Much like the 44221 straight driver, this version features a ball end. The regular 2mm type is great for putting lots of energy into the screw, but for the times when you need to go in at an angle, this is the tool.

The ball-tip allows for up to a 25 deg deflection off the screw’s axis for driving. Since it’s a finesse tool, applying too much torque can wear this driver down quicker. For final tightening of a screw, it is advisable to use the short end of a hex key. But even with these shortcomings, anybody who has used a ball-tip hex-driver will recognize it’s great usefulness!
