3M™ Vitrified Grinding Wheels 33VB consists of high-grade white aluminum oxide abrasive grit with a green V604, V904, or V304 vitrified bond and are available with various specifications for various applications. As a synthetic optimization of conventional standard bonds, the low temperature bond used in the PolarWin series allows for energy-saving firing at 900°C and 100% reproducibility.

• Powered by a mix of white and special alumina
• Designed to optimize the roughing and finishing grinding steps in generating grinding of gear parts
• Delivers high performance and durability while rough grinding
