... Resinoid and Vitrified Wheels Either vitrified or resinoid bond is used for thread grinding. Resinoid wheels remove stock more rapidly, but they are less rigid than vitrified wheels and deflect more readily. Therefore, resinoid wheels are usually used in high-production applications, while vitrified...
