If I understand the question correctly then you're asking about a sprag clutch.

When used in-line on a shaft like this, a sprag clutch permits torque to be transmitted out of the drill motor but not into the drill motor.

Any operation as a support bearing for the spinny-bits is kind of a secondary function at very best (and may be ill-advised; a sprag clutch assembly may be shaped kind of like a roller bearing assembly, but that doesn't mean that it will live long in that kind of role). :)
