Tuling Grit Tuling grit is an abrasive sand or powder—usually made of silicon carbide. It is placed in the tuling machine with rough rock. The grit is much harder than the rocks that you tule. As the rocks move in the tuler the grit gets caught between them and wears them away. This is an abrasive action similar to sand paper.
