3M 7000119253 Sanding Sheet Roll 320 Grit 2-3/4 in X 50 Yd

Product Description

The 3M 7000119253 is an adhesive-backed sanding sheet roll designed for precision surface finishing applications. It uses silicon carbide abrasive, which cuts fast and stays sharp on hard materials including composites, plastics, and non-ferrous metals. The roll measures 2-3/4 inches wide by 50 yards long, providing substantial run length before replacement. Backing weight is A, a lightweight paper backing suited for fine finishing passes. At 320 grit, this roll falls into the extra fine grade range, making it appropriate for final prep stages before sealing, painting, or coating. HVAC sheet metal fabricators, plumbers finishing pipe surfaces, and general tradespeople use this product where consistent scratch patterns and adhesive backing convenience are required.

This sanding roll is well suited for shop and field use where strips need to be cut to custom lengths and adhered directly to a backing block, drum, or flat surface. The 50-yard length supports high-volume finishing work or extended production runs without frequent roll changes. The 2-3/4 inch width fits standard sanding blocks and narrow-profile drum sanders. The silicon carbide abrasive performs consistently on hard, smooth substrates where aluminum oxide would load or glaze prematurely.

Key Features

• 320 grit extra fine silicon carbide abrasive for final-stage surface preparation
• Adhesive back allows direct application to sanding blocks, drums, or flat platens
• A-weight paper backing provides flexibility and conforms to flat and low-contour surfaces
• 50-yard roll length reduces changeover frequency in production environments
• 2-3/4 inch width compatible with standard narrow sanding blocks and drum fixtures

Compatibility

Designed as a general-purpose adhesive-back sanding roll for use with flat sanding blocks, drum sanders, and custom backing fixtures that accept 2-3/4 inch wide abrasive strips.

Installation Notes

Cut strips to the required length using a straightedge and utility knife before peeling the adhesive liner. Ensure the mounting surface is clean and dry before applying the strip to prevent premature lifting. Wear appropriate respiratory protection when dry sanding composites, plastics, or coated metals. Discard worn strips promptly, as a loaded abrasive will burnish rather than cut.
