3M 7000028479 Scotch-brite Exl Unitized Wheel 6 in Fine

Product Description

The 3M 7000028479 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses silicon carbide abrasive at a fine grit rating, making it well suited for finishing and light deburring passes where controlled cut and surface quality matter. Its soft, conformable construction allows the abrasive to maintain consistent contact with irregular or complex part geometries. Measuring 6 inches in diameter, this unitized wheel is built for use on bench grinders, angle grinders, and automated or robotic finishing equipment operated by metalworkers and fabricators.

This wheel is a practical choice for shops working with metal alloys, plastics, and composite materials that require clean edge finishing without smearing or heat damage. The layered, unitized construction supports operation in both clockwise and counterclockwise directions, giving it flexibility across different machine setups. It is particularly useful in robotic or automated processing lines where consistent abrasive contact with shaped parts is required. Manual finishing stations in fabrication, aerospace component prep, and general metalworking are common application environments.

Key Features

• Silicon carbide abrasive at fine grit provides controlled finishing and light deburring
• Soft, conformable construction maintains contact with complex and irregular part shapes
• Unitized layered structure supports both clockwise and counterclockwise operation
• Resists smearing for cleaner surface results with less prep work required
• Minimizes heat buildup, reducing risk of damage on heat-sensitive materials
• Wheel edge can be dressed to restore cutting performance during use

Compatibility

Designed for use on bench grinders, angle grinders, and robotic finishing equipment where a unitized wheel arbor mount is supported; suitable for finishing and deburring metal alloys, many plastics, and composite materials.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel mounting procedures. Always power down and lock out the machine before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the maximum rated RPM marked on the wheel. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
