3M 7100048080 Abrasive Paper Sheet 280 Grit 6000 Per Case

Product Description

The 3M 7100048080 is a silicon carbide abrasive paper sheet in the 405U series, designed for dry sanding applications across finishing and surface preparation work. Produced at 280 grit with an A-weight paper backing and an open coat construction, it delivers consistent scratch patterns and resists loading on a wide range of substrates. Each sheet measures 4.4375 inches x 4.4375 inches. This product is used by trades and finishing professionals who need a reliable, fine-grit sheet for detail sanding, between-coat finishing, and light material removal where controlled surface conditioning is required.

The 405U series paper sheet is suited for dry sanding operations on wood, paint, primer, and light metal finishing tasks. The open coat layout reduces clogging during use, making it effective on softer materials and coatings that tend to fill abrasive surfaces quickly. It is packaged in cases of 6000 sheets with 600 sheets per inner pack, supporting high-volume shop environments, production finishing lines, and service professionals who require consistent supply on hand.

Installation Notes

These sheets are intended for dry sanding only — do not use with water, oil, or other liquids. Secure the sheet firmly to a sanding block or compatible tool holder before use to prevent slippage and uneven scratch patterns. Inspect sheets periodically during use and replace when loading or wear reduces cutting efficiency. Dispose of used abrasive sheets in accordance with local regulations, particularly when sanding lead-based paints or hazardous coatings.
