A hole cleaning apparatus (100, 200) includes a member (106, 206, 406), a brush (120, 220, 420), and a vacuum source (114, 119, 214, 221, 414, 419). The brush (120, 220,420) rotates around a longitudinal axis (130, 230) of the member (106, 206, 406), or translates in a direction which is substantially parallel to the longitudinal axis (130, 230) of the member (106, 206, 406). The vacuum source (114, 119, 214, 221, 414, 419) provides vacuum suction within the member (106, 206, 406). |
