Product Overview
For outer diameter (OD) cylindrical grinding or reciprocating surface grinding, use 3M™ Vitrified Grinding wheels 33VH.
Our vitrified bonded grinding wheels contain a mix of pink coloured pure aluminium oxide and mono crystalline aluminium oxide grains, providing a much harder combination of abrasives than standard white aluminium oxide grits. These minerals are strong, but also offer a medium friability and cool cutting effect resulting in a long lasting and consistent abrasiveness.
They’re ideal for grinding specific materials such as hardened steel with hardness > 63 HRc and high tensile strength, hardened acid and heat resistant steel, stainless steel, high speed steel (HSS) or cast steel materials.
