1) Glue or epoxy a rare earth magnet inside. If you don't have one that is small enough, take a larger one and bash it with a hammer to get a piece small enough.
2) Take your least favorite bit and slightly grind or file it on one side of the shank. Stick it in the collar then bash the collar with a hammer on the side you ground on the bit. It will deform to make a snug fit for the rest of the bits.
