A revolutionary precision shaped ceramic grain was created that continually fractures into super-sharp points and edges that slice cleanly through metal, rather than gouging or ploughing as traditional abrasives do. This creates a super-fast cut and lessens heat build-up in the workpiece, reducing heat-related stress cracks and discoloration. Moreover, because the abrasive itself stays cooler and sharper, it lasts significantly longer than conventional ceramic grain belts, decreasing costs and reducing belt changeovers.
The exceptionally fast cut and long life of ceramic grain make this belt ideal for industrial environments. It is also heat resistant, produces a uniform finish over the life of the product, and helps eliminate burning during end-grain sanding applications. The X Wt Poly/Cotton backing on the 947A provides the perfect solution for low to medium dry applications
- 3M Precision Shaped Grain continuously fractures into sharp points that cut exceptionally fast, helping increase productivity
- 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
- X Wt Poly/Cotton backing excels in low/medium pressure applications
