3M 7100032489 Scotch-brite Unitized Wheel 3 in 3/8 in Arbor

Product Description

The 3M 7100032489 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive deburring, blending, and finishing on harder metals. The tightly layered, non-woven construction holds a high concentration of aluminum oxide abrasive mineral, delivering fast cutting action and a consistent bright finish from the first use through the life of the wheel. At 3 inches in diameter with a 3/8 inch arbor hole, this compact wheel is well suited for portable tool applications where access and maneuverability are priorities. It is available in medium to hard densities and weighs approximately 0.07 pounds.

This unitized wheel is intended for metalworking applications involving stainless steel, carbon steel, high nickel alloys, and similarly hard base materials. Its small diameter and narrow width make it a practical choice for jobs where larger wheels cannot reach or where portability is required. Typical uses include edge deburring, surface blending, and pre-finishing work in fabrication, maintenance, and repair environments. The flexible, non-woven structure provides controlled abrasive action that reduces the risk of undercutting or gouging the workpiece surface.

Key Features

• Tightly layered unitized construction operates in clockwise or counterclockwise rotation
• High abrasive mineral concentration cuts aggressively and produces a bright finish throughout wheel life
• Non-woven construction delivers controlled abrasive action, reducing risk of undercutting or gouging
• Scotch-Brite material resists loading and wears at a uniform rate for continuous cutting performance
• Compact 3 inch diameter supports portable tool use and tight-access applications
• Suited for deburring, blending, and finishing on stainless steel, carbon steel, and high nickel alloys

Compatibility

Designed for use with portable rotary tools and right-angle grinders accepting a 3/8 inch arbor. Best applied on harder metals including stainless steel, carbon steel, and high nickel alloys in fabrication, MRO, and finishing applications.

Installation Notes

Installation and use of abrasive wheels should follow ANSI B7.1 safety standards and the tool manufacturer's guidelines. Confirm the tool's rated RPM meets or exceeds the wheel's maximum operating speed before mounting. Power down and disconnect the tool from the power source before mounting or removing the wheel. Always use the correct arbor size and inspect the wheel for damage prior to each use.
