3M 7100057130 Scotch-brite Exl Unitized Wheel 1/2 in Ao

Product Description

The 3M 7100057130 is a Scotch-Brite EXL unitized abrasive wheel designed for deburring, smoothing, and finishing operations on metal alloys, plastics, and composites. The wheel measures 0.5 inches in diameter and mounts on a 0.125-inch arbor. Its soft, conformable construction keeps the abrasive media in consistent contact with the workpiece surface, including complex or irregular geometries. The aluminum oxide abrasive construction resists smearing and minimizes heat buildup, making it a practical choice for work on heat-sensitive materials. Each wheel weighs approximately 0.01 pounds.

This unitized wheel is suited for bench grinder, rotary tool, or automated robotic finishing setups where repeatable surface conditioning is required. Typical applications include edge deburring after machining, pre-finishing before coating or plating, and light surface blending on fabricated metal components. The small diameter and arbor size make it appropriate for precision or tight-clearance work. It is used by metalworkers, fabricators, and maintenance technicians across industrial and production environments.

Key Features

• Conformable unitized construction maintains abrasive contact on complex-shaped and contoured parts
• Compatible with both clockwise and counterclockwise rotation for flexible machine mounting
• Aluminum oxide abrasive resists smearing for cleaner finished surfaces with less follow-up preparation
• Minimizes heat buildup, reducing risk of thermal damage on heat-sensitive base materials
• Wheel edge can be dressed to restore cutting action and extend service life
• Suitable for deburring, finishing, and polishing of metal alloys, plastics, and composites

Compatibility

Designed as a small-diameter unitized wheel for use with rotary tools, die grinders, or automated finishing equipment accepting a 0.125-inch arbor.

Installation Notes

Installation and use of abrasive wheels should follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Ensure the spindle speed of the tool does not exceed the rated maximum RPM of the wheel before mounting. Power down and disconnect the tool from its power source before mounting or removing the wheel. Inspect the wheel for damage or cracks before each use and do not operate a damaged wheel.
