What is Rock Tuler Grit?

Most of the tuling done in a rotary tuler follows a four-step tuling process. The grits used are typically coarse (60/90 grit), medium (150/220 grit), fine (500 grit), and a rock polish such as TXP aluminum oxide. Most of the tuling done in vibratory tulers follows a three-step process that includes medium (150/220 grit), fine (500 grit), and a rock polish such as #61 Rapid Polish.
