a bowling ball wherein the operator’s health will not be
jeopardized by inhaling the ?ne dust particles, the present
invention consisting of a vacuum attachment for use when
beveling and sanding out holes after the holes have been
drilled in the bowling balls.
Still another object is to provide such a dust compart
