GH80 STEEL GRIT ABRASIVE FOR SHOTBLASTING
Steel Grit is made by crushing the fully hardened shot, screening the resulting media and tempering it to a desired hardness. Grit works best in tumblast applications where the eccentric rebound aids coverage. It is used in conting and/or rust removal where speed of cleaning is critical and somewhat rough finish is acceptable.
