3M 7000120556 Scotch-brite Unitized Wheel 3 Inch 1/4 Arbor

Product Description

The 3M 7000120556 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive deburring, blending, and surface finishing on harder metals. The wheel uses a tightly layered, non-woven construction with a high concentration of aluminum oxide abrasive mineral. This combination delivers fast cutting action and a consistent bright finish from the first use through the end of the wheel's service life. Available in a compact 3-inch diameter with a 1/4-inch arbor, it is well suited for portable tool applications. Fabricators, metalworkers, and maintenance technicians working on stainless steel, carbon steel, and high-nickel alloys are the primary users of this wheel.

This unitized wheel is used in light fabrication, general metalworking, and maintenance applications where portability and small tool clearance are required. The 3-inch diameter and 1/4-inch arbor make it compatible with die grinders and similar handheld rotary tools commonly used in shop and field settings. It performs well on deburring cut edges, blending weld seams, and preparing metal surfaces prior to finishing or coating. The unitized construction allows operation in both clockwise and counterclockwise directions, which adds flexibility when working in tight or restricted areas.

Key Features

• Aggressive deburring and blending performance on stainless steel, carbon steel, and high-nickel alloys
• High concentration of aluminum oxide mineral for fast cutting and consistent bright finish throughout wheel life
• Flexible, non-woven construction provides controlled abrasive action that reduces risk of undercutting or gouging
• Tightly layered unitized construction supports both clockwise and counterclockwise rotation
• Scotch-Brite material resists loading and wears at a uniform rate for continuous cutting action
• Compact 3-inch diameter suits portable tool applications and restricted-access work areas

Compatibility

Designed for use with die grinders and handheld rotary tools accepting a 1/4-inch arbor. Suited for deburring, blending, and finishing applications on harder metals including stainless steel, carbon steel, and high-nickel alloys.

Installation Notes

Installation and wheel mounting should be performed by a qualified metalworker or maintenance technician familiar with abrasive wheel safety. Ensure the tool is powered off and fully stopped before mounting or removing the wheel. Verify the tool's maximum RPM rating meets or exceeds the wheel's rated speed before operation. Follow ANSI B11 and applicable OSHA standards for abrasive wheel mounting and guarding requirements.
