5-Star Photo Review of Diablo H5 50mm Power Bit - 2 Pack

great quality hex drive bits from Diablo, these bits will last as long as you can't lose them for, properly forever. they have a slight magnet on the end which helps you lock in, and are a h5 size. honestly again they will last forever or until you lose them which is common. I go through a lot because I use them on roofs often. and they go well in a lot of things a Allen key will be used for. they are so tough you can easily thread a bolt.
