3M 7100225415 Ceramic Fibre Grinding Disc 5 Inch 40 Grit

Product Description

The 3M 7100225415 is a coated ceramic abrasive fibre disc built for aggressive material removal on metal, plastic, and fiberglass. Measuring 5 inches in diameter and rated at 40 grit, it delivers a fast cut rate with extended disc life thanks to 3M Ceramic Abrasive Grain technology. A resin bond construction stabilizes the disc under heat and pressure, reducing glazing and maintaining consistent cut performance throughout the disc's service life. Licensed tradespeople and fabricators reach for this disc when throughput matters and disc changes need to stay infrequent.

This disc is suited to grinding paint, rust, MIG welds, and door skins on automotive, sheet metal, and general fabrication work. It handles both ferrous and non-ferrous substrates, including metal, plastic, and fiberglass. The hub and retainer nut attachment system allows quick disc swaps on compatible angle grinders and disc grinders, minimizing downtime during heavy grinding sessions. It is available in a minimum order quantity of 5 discs per pack.
