3M precision shaped ceramic grain continuously fractures into sharp points that cut exceptionally fast, helping increase productivity Precision shaped ceramic grain is engineered to run cooler, reducing metal discoloration/oxidation and the chance of heat related stress cracks Precision shaped grain requires less pressure, which can mean less operator fatigue Belt life is significantly longer, producing more parts per belt and requiring fewer belt changes YF-weight backing excels in medium/high pressure stainless, cobalt chrome and nickel alloy applications
