What is that one-way bearing TFA mentions. I understand its purpose, but where does one acquire such a bearing?

TFA has a link to the amazon page for the bearing used. It's a bearing plus freewheel clutch. Most commonly (and in this specific case) it means sprag clutch[1], but it may be e.g. a ratchet/pawl[2] (like most bikes have) or a roller freewheel[3].

Thank you
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). :)
Thank you.
Would it need a standard bearing on only one side of the sprag clutch, or should I double them up on both sides?
Had the same question. The article has an Amazon link to the bearings.
