3M 7000046032 Hook Loop Disc 4.5 in Silicon Carbide

Product Description

The 3M 7000046032 is a hook and loop abrasive disc designed for surface conditioning, blending, and finishing on metal, wood, and composite materials. Built on a flexible non-woven construction with silicon carbide abrasive, this 4.5-inch disc delivers aggressive material removal at very coarse grade without loading quickly. The hook and loop attachment system allows fast disc changes without adhesive backing. Rated to 7000 RPM, it suits standard angle grinders and random-orbit sanders used in fabrication, maintenance, and surface prep applications. Licensed tradespeople and maintenance technicians working on metal fabrication or surface restoration will find this disc a reliable consumable for heavy conditioning work.

This disc is suited to metalworking and general surface conditioning tasks in both shop and field environments. Its flexible non-woven structure conforms to irregular or contoured surfaces, making it practical for weld blending, rust removal, and surface preparation prior to coating or inspection. The silicon carbide abrasive cuts hard materials efficiently and is commonly used on stainless steel, aluminum, and non-metallic surfaces where aggressive stock removal is needed without leaving deep scratch patterns.

Installation Notes

Install and remove discs only when the tool is powered off and fully stopped. Confirm the tool spindle speed does not exceed the 7000 RPM disc rating before operation. Wear appropriate PPE including eye protection and gloves when operating abrasive discs at speed. Inspect the disc for damage or delamination before each use and discard any disc showing signs of deterioration.
