Cast Steel Shot is the product of choice for cleaning in every type of wheel machine as well as room blast where nozzles are utilized in air blasting. Shot is generally employed in wheel machines where smoother finishes are required. It is also used in spin blast and conveyor applications when no rebound is present. Grit works best in tumblast applications where the eccentric rebound aids coverage. Airblast applications work best with high hardness grit for fast cleaning.
