3M 7010328480 Stikit 216U 5 Inch P400 Disc Roll

Product Description

The 3M 7010328480 is a coated abrasive disc roll in the Stikit 216U series, designed for finishing applications where fast changeover and consistent cut matter. Each roll delivers open-coat aluminum oxide discs on a lightweight A-weight paper backing with a pressure-sensitive adhesive (PSA) face for direct attachment to a Stikit backup pad. At P400 grit, these discs are suited for fine finishing and surface prep work. The roll format eliminates individual disc liners, reducing handling time and keeping the work area cleaner. A load-resistant coating on the abrasive surface helps extend disc life by reducing premature glazing from dust and swarf buildup.

These discs are used in woodworking, automotive bodywork, metal fabrication, and general surface finishing where a fine, consistent scratch pattern is required. The 5-inch diameter fits standard 5-inch Stikit backup pads sold separately. The open-coat construction performs well across a range of materials including wood, paint, primer, and light metals. Typical users include body shop technicians, finish carpenters, and general fabricators working in production or job-site environments where disc change frequency is high.

Key Features

• Roll format eliminates disc liners for faster changeover and higher productivity
• P400 grit aluminum oxide mineral delivers fine finishing scratch patterns
• Open-coat construction reduces loading from dust and debris on the disc surface
• Load-resistant coating extends abrasive grain life and maintains consistent cut rate
• A-weight paper backing provides flexibility suited to contour and flat finishing work
• PSA backing attaches directly to compatible Stikit backup pads without fasteners

Compatibility

Designed for use with 5-inch Stikit backup pads. Backup pad sold separately. Confirm backup pad PSA compatibility before use.

Installation Notes

Mounting is performed by hand — no tools required. Align the disc flush to the face of the backup pad before applying pressure to seat the adhesive. Ensure the backup pad face is clean and free of debris before attaching a new disc, as contamination reduces adhesion and can cause disc separation during use. Discard discs showing signs of loading, tearing, or reduced cut rather than attempting to clean and reuse.
