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.

Sorry, not my area. Just glue a piece of filecard material in a bearing,
like a battery post cleaner.
