3M 7000121902 Non-woven Abrasive Disc 6 Inch Ao

Product Description

The 3M 7000121902 is a non-woven nylon abrasive disc engineered for light deburring, surface cleaning, and final finishing on metal workpieces. Built on a high-strength open-web nylon construction, it resists tearing and fraying even under high pressure or when working irregular edges. The disc uses Aluminum Oxide mineral for consistent cutting action and a repeatable scratch pattern across ferrous and non-ferrous metals. At 6 inches in diameter with a 1/4-inch arbor hole, it mounts to standard angle grinders and finishing tools used by metal fabricators, maintenance technicians, and industrial trades professionals.

This disc is suited for applications where a controlled, smear-free surface finish is required before inspection, coating, or assembly. The open-web structure resists loading, meaning debris does not pack into the abrasive and shorten service life. It performs well on flat surfaces as well as contoured or irregular geometry where a rigid abrasive would skip or gouge. Typical use cases include weld cleanup, edge conditioning, and pre-coating surface prep on sheet metal, structural steel, and non-ferrous alloys.

Key Features

• High-strength non-woven nylon construction resists tearing and fraying during edgework and contour finishing
• Aluminum Oxide mineral delivers sharp, consistent cutting action on ferrous and non-ferrous metals
• Dense, stiff disc body withstands high pressure without folding, maintaining contact and improving throughput
• Open-web design is load-resistant, reducing debris buildup and extending disc service life
• Produces a uniform, smear-free finish suitable for pre-coating or final surface inspection
• 1/4-inch arbor center hole for direct mounting to standard grinder and finishing tool arbors

Installation Notes

Mounting and disc changes should be performed with the tool unplugged or the power source isolated. Verify the tool spindle speed rating meets or exceeds the maximum rated speed of the disc before use. Wear appropriate eye protection and gloves during disc installation and operation. Inspect the disc for damage before each use and replace if the web shows signs of tearing or separation.
