3M 7100141689 Non-woven Abrasive Roll 4in X 30ft Very Fine

Product Description

The 3M 7100141689 is a non-woven abrasive roll designed for surface finishing, blending, and light material removal across a wide range of trade and industrial applications. The roll measures 4 inches wide by 30 feet long, giving technicians and tradespeople a large working supply that can be cut to length as needed. The abrasive mineral is silicon carbide, rated Very Fine grade, and the roll is gray in color. Silicon carbide cuts aggressively for its grade, making this roll well-suited for final surface prep, deburring, and blending scratches on metal, composites, and other hard substrates. Total roll weight is 4.8 pounds.

This non-woven abrasive roll is used across HVAC, plumbing, electrical, and general metal fabrication workflows wherever a controlled, consistent surface finish is required. Common applications include cleaning and prepping pipe ends before brazing or soldering, deburring sheet metal edges, scuffing painted or coated surfaces before repair, and blending weld seams. The 30-foot length makes it practical for shops and field technicians who need a bulk supply on hand. The Very Fine silicon carbide grade is best applied as a finishing step after coarser material removal is complete.

Key Features

Installation Notes

Cut to the desired length using shears or a utility knife before use. Wear appropriate hand and eye protection when working with abrasive materials on metal surfaces. Ensure the workpiece is secure before applying abrasive pressure. Follow applicable shop safety guidelines and any jobsite PPE requirements.
