At times I found the little one inch bits sometimes don’t stay in the magnetic holder, that’s why I like the two or even three inch bits that go directly into the impact and no holder
Magnetic holders that have a retaining ring built in to engage the detents on the corners of the bits are my favourites but they are so hard to find. They are most common in industrial components which usually carry a pretty hefty price, too.
Actually I have one in my dewalt impact bit set, it’s good, really holds the bits in, so good I need pliers to get those little one inch bits out
