3M Vitrified Grinding Wheels 33VI are our vitrified bonded grinding wheels with ruby coloured pure aluminium oxide grains for special grinding operations.Use 3M Vitrified Grinding Wheels 33VI for profile grinding of high alloy steel, gear grinding, or outer diameter cylindrical grinding.
Our vitrified bonded grinding wheels contain ruby coloured pure aluminium oxide grains which are moderately harder than standard white aluminium oxide minerals.
They’re ideal for grinding specific materials of higher tensile strength, such as high alloyed and toughened steels used in the tooling industry, including high speed steel, and hardened steel.
