3M 7000046021 Scotch-brite Unitized Wheel 2 Inch Silicon Carbide

Product Description

The 3M 7000046021 Scotch-Brite Clean and Strip Unitized Wheel is a compact abrasive wheel engineered for aggressive coating removal in industrial and maintenance applications. Built with a layered, unitized construction and rated at a hard density 7 with low conformability, this wheel delivers strong, controlled cutting action on edges and tight geometry. Silicon carbide abrasive provides extra coarse cutting that attacks rust, weld scale, paint, and surface coatings without undercutting the base material. At 2 inches in diameter and weighing 0.05 pounds, it fits small angle grinders and die grinders used by metalworkers, fabricators, maintenance mechanics, and industrial trades.

This wheel is suited for rust and coating removal on ferrous and non-ferrous metal surfaces in both shop and field environments. The low conformability and hard density make it particularly effective when working along edges, shoulders, and recessed areas where flexible wheels would lose cutting efficiency. It can be run clockwise or counterclockwise, adding flexibility to multi-tool setups. Typical applications include weld cleanup, pre-paint surface prep, and corrosion removal on structural steel, pipe, and fabricated components.

Key Features

• Extra coarse silicon carbide abrasive for aggressive rust, paint, and coating removal
• Hard density 7 construction with low conformability for controlled cutting on edges and tight areas
• Layered unitized construction operates in both clockwise and counterclockwise directions
• Resists heat buildup and loading on soft coatings for prolonged, consistent operation
• More effective and safer for coating removal than wire wheels or wire cups
• Compact 2-inch diameter fits standard die grinders and small angle grinders

Compatibility

Designed for use with die grinders and small angle grinders accepting 2-inch diameter unitized abrasive wheels. Verify arbor size and maximum RPM rating of the tool before mounting.

Installation Notes

Installation and wheel changes must be performed with the grinder unplugged or pneumatic supply disconnected. Inspect the wheel for damage before mounting and never exceed the maximum RPM rating marked on the wheel or packaging. Eye protection and appropriate PPE are required during operation. Follow ANSI B7.1 and tool manufacturer guidelines for abrasive wheel mounting and use.
