3M 7100077738 Scotch-brite Unitized Wheel 2 in Silicon Carbide

Product Description

The 3M 7100077738 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 2-inch diameter wheel operates in either clockwise or counterclockwise direction and resists loading throughout its service life. The silicon carbide abrasive mineral delivers fast cutting action and consistently produces a bright finish from first use to last. Its compact diameter and narrow width make it well suited for portable tool applications and tight-access work areas.

This unitized wheel is used in metalworking and fabrication environments where surface finishing on harder metals is required. Typical applications include deburring, surface blending, and finish work on stainless steel, carbon steel, and high nickel alloys. The controlled abrasive action of the flexible, non-woven construction helps prevent undercutting or gouging, making it appropriate for both production and maintenance finishing tasks. It suits applications where small-diameter wheel availability and portability are priorities.

Key Features

• Tightly layered unitized construction operates in clockwise or counterclockwise rotation
• Silicon carbide abrasive provides fast cutting and a bright finish throughout wheel life
• Non-woven, flexible construction delivers controlled abrasive action and reduces risk of undercutting or gouging
• Scotch-Brite material resists loading and wears uniformly for continuous cutting performance
• Compact 2-inch diameter supports portable tool use and access to tight work areas
• Suited for harder metals including stainless steel, carbon steel, and high nickel alloys

Compatibility

Designed for use on harder metals including stainless steel, carbon steel, and high nickel alloys in deburring, blending, and surface finishing applications requiring a 2-inch diameter unitized wheel.

Installation Notes

This wheel is typically installed and operated by machinists, fabricators, or maintenance technicians using portable or bench-mounted rotary tools. Before mounting, verify that the tool spindle speed does not exceed the maximum rated RPM marked on the wheel. Ensure the tool is powered off and disconnected before changing wheels. Wear appropriate PPE including eye protection and gloves during installation and operation.
