The Sigma green 60-grit grinding wheels are thin and flexible, which the company claims, provides better operator control.  These grinding wheels feature a proprietary blend of zirconium/ceramic grain, which is said to be suitable for light-weld removal and finishing applications on stainless steel and aluminum.   The company also claims that these bonded grinding wheels work fast and outlast flap discs.

The grinding wheels come in 4½" × 7/8" and 4½" × 5/8" to 5/11" sizes and are available with or without hubs. The company says the line is offered in a variety of grit sizes for grinding harder materials such as inconel and titanium.
