3M 7100078003 Abrasive Disc Roll 5 Inch 80 Grit Ceramic Ao

Product Description

The 3M 7100078003 is a coated abrasive disc roll designed for aggressive material removal in woodworking, paint prep, and metal finishing applications. Each disc features an 80-grit ceramic aluminum oxide blend abrasive on a heavy F-weight paper backing, delivering high cut rates and extended service life compared to conventional aluminum oxide products. The pressure-sensitive adhesive (PSA) backing is compatible with Stikitt disc pads, allowing fast disc swaps without tools. This roll format reduces per-disc cost and minimizes changeover time, making it a practical choice for production shops, fabrication facilities, and finishing contractors.

This disc roll is suited for rotary tool and random orbital sander use on wood, painted surfaces, and ferrous and non-ferrous metals. The 5-inch diameter fits standard 5-inch PSA disc pads. Applications include rough shaping, seam leveling, weld grinding preparation, and intermediate paint prep. The disc roll format is especially practical in environments with high disc turnover, where loading individual packaged discs creates workflow slowdowns.

Key Features

• Ceramic aluminum oxide blend self-sharpens during use for sustained cut rate and long abrasive life
• Heavy F-weight paper backing resists tearing under aggressive stock removal pressure
• PSA Stikitt backing allows quick application and clean removal from compatible disc pads
• Roll format reduces per-disc cost and supports high-volume finishing operations
• Compatible with rotary tools and random orbital sanders
• 5-inch diameter fits standard PSA-style backup pads

Compatibility

Designed for use with 5-inch Stikitt PSA disc pads on rotary tools and random orbital sanders. Consult tool and pad manufacturer specifications to confirm PSA backing compatibility before use.

Installation Notes

Mounting and disc changes should be performed with the sander unplugged or the air supply disconnected. Press the disc firmly onto the PSA pad, ensuring full contact across the face to prevent edge lifting during operation. When removing the disc, peel slowly from the edge to keep the pad surface clean for the next application. Follow applicable workplace safety standards for abrasive tool operation, including appropriate eye and respiratory protection.
