3M 7000046034 Hook Loop Abrasive Disc 4.5 in Aluminum Oxide

Product Description

The 3M 7000046034 is a 4.5-inch hook and loop abrasive disc built for surface preparation, blending, and finishing work across metal, wood, and composite substrates. The disc uses an aluminum oxide abrasive in a non-woven construction, delivering consistent cut and surface conditioning at medium grade. Its flexible design conforms to contoured surfaces, making it well suited for work that requires even stock removal without aggressive gouging. A maximum speed rating of 13,000 RPM allows use on standard angle grinders and disc sanders. Trade professionals in HVAC fabrication, plumbing rough-in, and general mechanical work reach for this disc when prepping pipe ends, weld seams, or panel surfaces.

This disc is used in light industrial and trade environments where controlled surface conditioning is required. The non-woven aluminum oxide construction makes it effective for deburring, blending welds, removing mill scale, and prep work before coating or assembly. The maroon color indicates medium-grade abrasive action within the SE-DH series. No vacuum holes are present, so it is compatible with standard hook and loop backing pads that do not require dust extraction ports. It suits residential and commercial service work where a consistent, repeatable scratch pattern is needed without aggressive material removal.

Key Features

Compatibility

Designed for use with standard hook and loop backing pads accepting 4.5-inch non-woven abrasive discs. No vacuum hole pattern; verify backing pad type before use.

Installation Notes

Installation is performed by pressing the disc firmly onto a compatible hook and loop backing pad mounted to an angle grinder or disc sander. Confirm the tool's rated RPM does not exceed 13,000 RPM before operation. Inspect the disc and backing pad for wear or damage before each use, and replace if the hook and loop interface no longer holds securely. Always wear appropriate eye and hand protection when operating abrasive tooling.
