3M 7000144599 Scotch-brite Exl Unitized Wheel 6 in Ao

Product Description

The 3M 7000144599 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Built with a layered, unitized construction, the wheel maintains a consistent cut throughout its life as the abrasive mineral is distributed uniformly through the wheel body. At 6 inches in diameter with a 1-inch arbor bore, it mounts directly to bench grinders, angle grinders, and finishing machines used in fabrication and metalworking shops. The aluminum oxide abrasive mineral resists smearing and minimizes heat buildup, making it well-suited for finishing heat-sensitive materials and producing clean, consistent surface finishes.

This wheel is used in industrial fabrication, metal finishing, and light deburring operations across a range of materials including aluminum, stainless steel, mild steel, and many engineering plastics and composites. The soft, conformable consistency allows the abrasive to maintain contact with irregular or complex-shaped workpieces, including parts processed through robotic or automated finishing systems. It runs in both clockwise and counterclockwise directions, offering flexibility in machine setup. Fabricators, machinists, and finishing technicians are the primary users in job shop and production environments.

Key Features

• Layered unitized construction delivers consistent cut from first use to last
• Runs clockwise or counterclockwise for flexible machine compatibility
• Conformable structure maintains abrasive contact on complex and irregular part geometries
• Minimizes heat buildup to protect heat-sensitive metals and plastics
• Resists smearing for cleaner surfaces and reduced prep between passes
• Wheel edge can be dressed for targeted deburring, finishing, and polishing work

Compatibility

Designed for use on bench grinders, angle grinders, and automated finishing equipment fitted with a 1-inch arbor; suitable for deburring and surface finishing of metal alloys, plastics, and composites.

Installation Notes

Installation is performed by machinists or finishing technicians following standard machine guarding and wheel-mounting procedures. Always power down and de-energize the machine before mounting the wheel and confirm the spindle speed does not exceed the rated RPM of the wheel. Verify the arbor bore fits the spindle without forcing, and use appropriate flanges and hardware as specified by the machine manufacturer. Inspect the wheel for damage before each use and do not operate a damaged or out-of-round wheel.
