47134 SILVER T27 DEPRESSED CENTER GRINDING DISC 115MM X 7MM X 22MM™ CF 20 PCS 3M

3M™ Silver Grinding Disc - 115 mm x 7 mm x 22.23 mm

The 3M™ Silver disc (ID 7100141083) represents the state of the art for Type 27 industrial grinding operations. Developed to handle aggressive applications, it maintains a high cutting rate throughout its operating life.

Benefits and Exclusive Features

• 3M™ Precision Shaped Grain (PSG) Technology: Triangular-shaped ceramic grains continuously fracture during use to form consistently sharp points and edges. This allows the disc to cut cleanly into metal, preventing substrate erosion and excessive heat buildup.
• Increased Productivity: The extraordinary cutting speed allows you to complete more pieces in less time, optimizing work shifts and reducing the frequency of disc changes.
• Cold Work: The PSG grain design minimizes thermal friction, protecting sensitive metals like stainless steel from discoloration, oxidation, or stress cracking.
• Multi-Metal Versatility: Extremely effective on a wide range of substrates, including carbon steel, stainless steel, high speed steel and aerospace alloys.
• Operating Comfort: Requires less pushing pressure than traditional discs, improving ergonomics and reducing physical stress for the professional.
