3M 7000046018 Hook Loop Abrasive Disc 4.5 in Aluminum Oxide

Product Description

The 3M 7000046018 is a hook and loop non-woven abrasive disc designed for surface conditioning, blending, and finishing on metal, wood, and composite materials. Built around aluminum oxide abrasive in a medium grade, the disc mounts to any hook and loop backing pad rated for a 4.5-inch disc and runs up to 13,000 RPM. The flexible, non-woven construction conforms to contoured surfaces, allowing consistent material contact without aggressive stock removal. The maroon color identifies medium-grade cut. This disc is a single unit sold in a minimum order quantity of five.

This disc is suited for deburring, light blending, and surface prep on fabricated metal components, welded joints, and finished woodwork. Its non-woven abrasive matrix resists loading and provides a consistent scratch pattern, making it a reliable choice for finish prep work before coating or painting. It is commonly used by metal fabricators, industrial maintenance technicians, and general tradespeople working with angle grinders or random orbital tools fitted with a hook and loop pad.

Installation Notes

Mount the disc firmly onto a clean, dry hook and loop backing pad before powering the tool. Verify the tool RPM rating does not exceed 13,000 RPM before use. Inspect the disc and backing pad for wear or damage before each session and replace if the hook and loop interface no longer seats securely. Follow applicable ANSI and OSHA abrasive wheel safety standards when operating rotary grinding tools.
