... sand has less inherent strength than does the metal; therefore, it breaks down without metal damage. Many foundries use hand-held, vertical, A-frame, or fixtured air tools that operate in the 1000 to 3000 blows per minute range. The hand-held air tool method of decoring castings involves an operator...
