This is a premium, professional-grade 1A1R Resin Bond Diamond Wheel designed for high-precision grinding and finishing. Manufactured in the USA, this wheel features a High Diamond Concentration, providing a faster cut rate and significantly longer tool life compared to standard concentration wheels.
The Resin Bond is specifically engineered to be "self-sharpening," meaning the bond breaks down at a controlled rate to constantly expose fresh, sharp diamond particles, ensuring a cool, chatter-free grind.
