3M 7000047209 Non-woven Abrasive Disc 8 in Ao

Product Description

The 3M 7000047209 is a non-woven nylon abrasive disc designed for light deburring, surface cleaning, and final finishing on metal workpieces. Built on a high-strength open web construction, the disc resists tearing and fraying even when working edges or irregular contours. Aluminum oxide mineral provides a sharp, consistent cut and produces a uniform scratch pattern across both ferrous and non-ferrous metals. The 8-inch diameter and 1/2-inch arbor hole make it compatible with standard bench grinders and angle grinders used in fabrication and finishing applications. Metalworkers, machinists, and maintenance technicians are the primary installers and users of this disc.

This disc is suited for production and job-shop environments where consistent surface prep and light material removal are required before final inspection or coating. The high-strength grade within the Buff and Blend product line is optimized for tasks where a smear-free, polished result is needed without aggressive stock removal. It performs well on steel, aluminum, stainless, brass, and similar metals. The dense, stiff construction holds up under higher contact pressure without folding, which improves throughput when working on flat or contoured surfaces.

Installation Notes

Mounting and disc changes should be performed by a qualified operator with the grinder fully powered down and unplugged. Verify the grinder spindle speed does not exceed the maximum rated RPM marked on the disc before use. Inspect the disc for damage before each use and replace if the web shows signs of tearing or excessive wear. Always use appropriate eye and face protection when operating abrasive discs.
