How to use

Insert a compatible 1/4" (6.3 mm) bit into the holder until it clicks to engage the SelfLock mechanism. Use the bit holder with hand drivers or compatible power drivers that accept a 1/4" hex shank. To remove the bit, activate the EasyOut ejection function according to the tool orientation and pull the bit free.
