Can you make this for my customer?
Take a ball bearing with inner diameter larger than the drill bit.
> Place wire brushes on the inside that fits around the shank of the
> drill bit and into the flutes. The brushes have to be soft/flexible
> enough not to dull the bit, but firm enough to clean out the flutes.
> The collar sits on the drill bit above the work piece. The inside of
> the bearing is "attached" to the drill bit by the friction and
> pressure of the brushes, and the outside of the bearing is attached to
> an arm that holds it above the workpiece.
>
> When the drill bit spins up, the inner collar spins with it, since it
> is not fixed to anything other than the drill bit. The brushes are
> stationary with respect to the spinning drill bit (spinning at the
> same speed). When the drill moves down into the work piece and up out
> of it, the brushes follow the flutes and clean out the gunk.
