3M 7100189462 Scotch-brite St-uw Unitized Wheel 3 Inch

Product Description

The 3M 7100189462 is a Scotch-Brite ST-UW unitized abrasive wheel designed for deburring and surface finishing on demanding alloys. Built with a layered unitized construction, this wheel runs cooler than many alternatives and resists loading, which extends service life during high-contact grinding and blending operations. At 3 inches in diameter, it fits smaller spindles and portable equipment where larger convolute wheels cannot reach. Silicon carbide abrasive makes it well suited for hard-to-finish materials including stainless steel and titanium. Unitized construction allows for narrower widths and tighter diameters than convolute wheels, enabling more precise finishing work on intricate shapes and contours.

This wheel is used in metal fabrication and finishing applications where conformability and control matter more than aggressive stock removal. It suits both bench-mounted and portable grinders and performs equally well running clockwise or counterclockwise. Typical applications include deburring tight radii, finishing weld seams, and blending surfaces on aerospace, food service, and industrial components made from stainless steel, titanium, and other hard alloys. The wheel is sold individually.

Key Features

• Layered unitized construction runs clockwise or counterclockwise without performance loss
• Silicon carbide abrasive suited for stainless steel, titanium, and other demanding alloys
• Resists loading and runs cool, extending wheel life in continuous-use applications
• 3-inch diameter fits smaller spindles and portable grinding equipment
• Conforms to intricate shapes and contours for consistent surface finishing
• Narrow-width capability enables precise work in tight spaces and small-diameter bores

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive wheel for bench grinders, die grinders, and portable finishing equipment accepting 3-inch diameter unitized abrasive wheels.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B11 and applicable shop safety standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for damage before each use and confirm the spindle speed rating does not exceed the wheel's rated RPM. Do not use side pressure beyond what the wheel construction is rated for.
