3M™ Vitrified Grinding Wheels 33VC are our vitrified bonded grinding wheels with special white aluminium oxide grains and a green bonding system for conventional precision grinding operations.

• Aluminium oxide 54A grains, with vitrified bond
• Ideal for non-alloyed or low alloyed non-hardened steels, or alloyed steels, hardened up to 60-63 HRc
• Low friability and high wear resistance
• More durable than standard white Al2 O3 specifications when combined with green bonding system
• Outperforms when grinding cast iron, or stainless steel materials
