When cutting stainless steel grates, thin Type 27 abrasive cutting wheels with a resin bond offer a special combination of zirc-za and white aluminum oxide-ao, which allows for cool cutting of stainless steel and high tensile alloys. These Zirconia alumina wheels outlast standard aluminum oxide wheels 3 to 1 and have twice the cut rate.

A Metabo Angle Grinder is used here.
