3M 7100045947 Scotch-brite Unitized Wheel 4 Inch Silicon Carbide

Product Description

The 3M 7100045947 is a Scotch-Brite Clean and Strip Unitized Wheel designed for aggressive surface preparation tasks including coating removal, weld cleaning, rust removal, and paint stripping. Built with a layered unitized construction and a hard density rating of 7, this wheel delivers low conformability and strong cutting action. The silicon carbide abrasive grade is extra coarse, making it well suited for fast material removal on edges and contoured surfaces where durability is critical. Fabricators, maintenance techs, and metalworkers reach for this wheel when wire wheels and cups fall short on safety or consistency.

This unitized wheel is used in light industrial, fabrication, and maintenance applications on metal surfaces. Its low conformability makes it particularly effective on edges and in hard-to-reach areas where controlled, aggressive cutting is needed. The wheel is rated for both clockwise and counterclockwise operation, adding flexibility for angle grinder setups common in field and shop environments.

Key Features

• Hard density 7 construction with low conformability for strong edge cutting action
• Silicon carbide extra coarse abrasive removes rust, paint, and coatings efficiently
• Layered unitized design operates in both clockwise and counterclockwise directions
• Resists heat buildup and loading on soft coatings for prolonged, consistent operation
• Safer and more effective for corrosion and coating removal compared to wire wheels and cups
• Reaches hard-to-access areas where flat or cupped abrasives cannot

Compatibility

Designed as an OEM-style replacement and standard fitment for 4 inch angle grinders and die grinders used in metal surface preparation and coating removal applications.

Installation Notes

Installation and mounting should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Always confirm the spindle speed of the grinder does not exceed the maximum rated RPM of the wheel before mounting. Power down and disconnect the tool before changing wheels. Inspect the wheel for cracks or damage before each use and never use a damaged wheel.
