3M 7010330834 Non-woven Abrasive Disc 4 Inch 1/4 Inch Arbor

Product Description

The 3M 7010330834 is a non-woven abrasive disc engineered for light-duty blending, cleaning, deburring, and finishing on a variety of metal surfaces. Built on a tough nylon web construction with aluminum oxide (AO) mineral, it delivers a moderately aggressive cut that leaves a consistent, professional surface finish. The open web design resists loading, which reduces debris buildup and extends working life compared to solid abrasive discs. Sized at 4 inches in diameter with a 1/4-inch arbor, it mounts to standard right-angle grinders and disc tools used in fabrication and maintenance settings. It is color-coded maroon, indicating a medium-grade non-woven classification.

This disc is suited for light industrial and metal fabrication applications where the goal is surface prep, scale removal, weld blending, or pre-finish cleaning rather than aggressive stock removal. Common use cases include deburring cut edges, blending weld seams, removing surface oxidation, and preparing metal for coating or inspection. It performs well on mild steel, stainless steel, aluminum, and other common shop metals. Maintenance technicians, fabricators, and industrial metalworkers are the primary users of this type of disc.

Installation Notes

Install this disc on a grinder or finishing tool rated for the disc diameter before connecting power. Verify the arbor size and tool RPM rating are compatible with the disc before operation. Wear appropriate PPE including eye protection and gloves when operating abrasive discs. Inspect the disc for damage before each use and replace if the web shows signs of tearing or excessive wear.
