Another truly useful product from Wiha, these 50mm long 1/4" hex drive bits feature a TORX ball end allowing them to operate at an angle of up to 25° from the vertical. The option of being able to drive at a slight angle safely is a great advantage in a tight corner. Even better is being able to extract a misaligned screw quickly and easily. The set of three includes the more common sizes T20, T25 and T30.

DisappointingI bought these despite the previous reviews, and have to say I am disappointed. I have long thought Wiha products were well made and haven't had any problems, but after about my tenth screw (axminster woodspur - great screws) the T25 bit snapped off at the small radius, meaning I can still use it, but not for how it was designed; ie. driving screws at an angle. I can only presume it is a tempering issue.

Wiha TORX bitGood idea, but because the driving surface is small they round off in no time at all and are then useless!
