3M™ Cubitron™ II Hookit™ Cloth Disc 947A offers revolutionary performance with 3M Precision Shaped Ceramic Grain on an X-weight polyester-cotton cloth backing. Our high-performing disc contains a grinding aid, making it ideal for medium to high-pressure applications on stainless steel and other alloys, along with carbon steel, cobalt chrome, and nickel alloys. 3M Precision Shaped Ceramic Grain uses 3M Microreplication Technology to form sharp peaks that easily slice through metal — cutting cooler, faster and lasting longer than conventional abrasive grain. The X-weight poly-cotton backing delivers outstanding tear-resistance, flexibility, and a consistent, uniform finish on a variety of substrates. 3M™ Cubitron™ II Hookit™ Cloth Disc 947A is available in a range of grits, to meet the most demanding job requirements. Grits 40+ and 60+ can be used for many specialized construction applications, such as shaping and dimensioning fiberglass architectural elements. Grits 80+ and 120+ are ideal for leveling and blending the metal surface especially in automotive ‘body-in-white' applications. Convenient 3M™ Hookit™ Discs are ideal for high volume, quick change operations. Easy to attach and easy to remove, they leave a clean surface for the next disc.
