3M 7000148249 Scotch-brite Exl Unitized Abrasive Wheel

Product Description

The 3M 7000148249 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 1 inch in diameter with a 3/16 inch arbor bore. Its layered, unitized construction uses aluminum oxide abrasive mineral bonded into a soft, conformable structure that maintains consistent contact with the workpiece surface throughout the wheel's life. This type of wheel is commonly used in fabrication shops, metalworking facilities, and manufacturing environments by machinists, fabricators, and finishing technicians.

This wheel is suited for edge finishing, deburring, and light material removal on ferrous and non-ferrous metals, as well as many plastics and composites. The small 1 inch diameter and 3/16 inch arbor make it appropriate for use on rotary tools, die grinders, and small bench-mounted spindles where access to tight geometry or complex part profiles is required. Its conformable construction also makes it compatible with robotic or automated finishing processes where consistent abrasive contact is critical.

Key Features

• Unitized, layered construction operates in clockwise or counterclockwise rotation
• Conformable consistency keeps abrasive in contact with complex or irregular part profiles
• Resists smearing for cleaner surface results and reduced prep time
• Minimizes heat build-up, reducing thermal impact on heat-sensitive materials
• Wheel edge can be dressed for targeted deburring, finishing, and polishing
• Available across a range of densities and grades from soft and conformable to hard and aggressive

Compatibility

Designed for use on rotary tools, die grinders, and small spindle machines accepting a 3/16 inch arbor, for deburring and finishing applications on metal alloys, plastics, and composites.

Installation Notes

Mounting and use of abrasive wheels should follow ANSI B7.1 safety standards and the tool manufacturer's maximum RPM rating — never exceed the rated speed of the wheel or the tool. Power down and disconnect the tool before mounting or changing the wheel. Inspect the wheel for damage before each use and discard any wheel that shows cracking, fraying, or delamination. Eye protection and appropriate PPE are required during operation.
