Abstract

A shield useful, in conjunction with an air gun with a medium conduit, in flushing debris from a blind hole. It comprises a case, an exhaust clearance, a hanger, a bottom clearance, and at least one guide with a clearance, and a plug useful for plugging an unused guide clearance. The medium conduit is inserted through a guide clearance which directs a medium, such as compressed air or nitrogen or liquid, towards the blind hole. The medium and debris from the blind hole flow out the exhaust clearance.
