3M 7000120788 Scotch-brite Unitized Wheel 3 in 3/8 in Arbor

Product Description

The 3M 7000120788 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive deburring, blending, and finishing on harder metals. Built with a tightly layered, non-woven construction, this wheel holds a high concentration of aluminum oxide abrasive mineral that cuts fast and delivers a bright, consistent finish from first use through the end of the wheel's life. At 3 inches in diameter with a 3/8 inch arbor, it is well suited for portable tools and tight-access applications where larger wheels cannot reach. It is available in medium to hard densities. Fabricators, metal finishers, and maintenance technicians are the primary users of this wheel.

This wheel is applied to deburring, surface blending, and finish work on stainless steel, carbon steel, and high-nickel alloys. Its compact 3 inch diameter makes it an effective choice when small diameters and narrow widths are required, such as edge work, internal radii, and detail finishing on fabricated parts. The flexible, non-woven construction provides controlled abrasive action that reduces the risk of undercutting or gouging the base material, making it appropriate for applications where surface integrity is critical.

Key Features

• Tightly layered unitized construction operates in both clockwise and counterclockwise directions
• High abrasive mineral concentration delivers fast cutting and a consistent bright finish throughout wheel life
• Non-woven flexible construction minimizes undercutting and gouging on finished surfaces
• Scotch-Brite material resists loading and wears at a uniform rate for continuous cutting action
• Compact 3 inch diameter supports portable tool use and small-access finishing work
• Suited for harder metals including stainless steel, carbon steel, and high-nickel alloys

Compatibility

Designed for use with portable rotary tools and bench-mounted spindles accepting a 3/8 inch arbor. Intended for metal deburring, blending, and finishing applications on harder metals such as stainless steel, carbon steel, and high-nickel alloys.

Installation Notes

Mounting and operation of abrasive wheels should follow ANSI B7.1 safety standards and the tool manufacturer's speed ratings. Verify the tool's maximum RPM does not exceed the wheel's rated speed before mounting. Always power down and disconnect the tool before changing wheels. Wear appropriate eye and face protection during operation.
