For pulling wire, this installer bit includes fish eye holes on both ends—handy when you need to pull from either direction without backing out and re-threading. It also uses a 3-flat shank (3/16″ diameter) that’s compatible with standard 3-point drill chucks and helps reduce slipping during drilling.
