3M Precision Shaped Grain maintains super-sharp points, cuts exceptionally fast with less pressure

• PSG runs cooler, reducing metal discoloration/oxidation and the chance of heat related stress cracks
• Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes
• 3M™ Roloc™ attachment system provides for easy disc changes between grades or applications
• Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding
