1/4" bit adapter: 1/4" square (female) to 1/4" hex (female)
A 1/4" square to hex adapter is not a complicated tool. The Felo has a strong-but-not-too-strong retaining clip and is distinguishable at a glance from a 1/4" hex socket.
Good quality small and slim adapter for 1/4 square drive to 1/4 hex bits.
Buy a few, have one where you need it. Bought it to use in motorcycle travel toolkit. Holds bit good and tight, yet can easily insert and remove the bits.
Good price on a quality product.
Great little accessory for 1/4" bits. Very well made with a spring to retain the insert bit. KC Tool beats everyone on this one.
