3M 7100229788 Non-woven Buff Blend Hs Disc 24 Inch Ao

Product Description

The 3M 7100229788 is a high-strength non-woven nylon abrasive disc engineered for light deburring, surface cleaning, and final finishing on metal workpieces. Built around an open-web aluminum oxide construction, it delivers a uniform, smear-free scratch pattern on both ferrous and non-ferrous metals. The disc measures 24 inches in diameter and is rated for operation up to 1100 RPM. Its dense, stiff nylon matrix resists folding under pressure and holds its form when working edges or irregular contours, making it a dependable choice for fabricators and finishing technicians who need consistent, repeatable results across production runs.

This disc is suited for metal fabrication shops, maintenance environments, and finishing operations where light deburring and surface prep precede coating or polishing. The open-web structure resists loading, which reduces clogging and extends usable disc life. It performs on steel, stainless steel, aluminum, and other common shop metals. The center-hole disc format fits standard disc grinder and finishing machine arbors used in industrial and light manufacturing settings. Technicians handling weld cleanup, edge conditioning, or pre-coat surface prep will find this disc a practical fit for medium to high-volume work.

Installation Notes

Installation and disc changes should be performed by trained personnel with the machine fully de-energized and isolated from its power source. Verify that the machine spindle speed does not exceed the 1100 RPM rating of this disc before operation. Inspect the disc for damage before mounting and ensure the arbor and backing plate are clean and correctly sized for the 24-inch format. Follow applicable ANSI and OSHA standards for abrasive wheel mounting and guarding.
