3M 7000045936 Scotch-brite Exl Unitized Wheel 6 in 1/2 in Arbor

Product Description

The 3M 7000045936 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses aluminum oxide (AO) abrasive mineral embedded in a soft, conformable, layered construction that maintains consistent contact with workpiece surfaces throughout the life of the wheel. At 6 inches in diameter with a 1/2-inch arbor, it mounts on standard bench grinders, angle grinders, and automated finishing equipment. Weighing 0.36 pounds, it is a practical choice for both manual and robotic processing lines where heat control and surface cleanliness are priorities.

This unitized wheel is suited for fabrication shops, metal finishing operations, and automated production environments. It performs deburring, edge blending, and light surface conditioning on ferrous and non-ferrous metals as well as many plastics and composites. The conformable structure makes it effective on complex or contoured part geometries, whether run on a fixed spindle or integrated into robotic tooling. It is appropriate for use by machinists, fabricators, and industrial finishing technicians.

Key Features

• Soft, conformable layered construction maintains abrasive contact on complex and contoured surfaces
• Operates in both clockwise and counterclockwise directions for versatile mounting
• Minimizes heat build-up, reducing risk of damage to heat-sensitive materials
• Resists smearing for cleaner finished surfaces and reduced prep time
• Wheel edge can be dressed for targeted deburring, finishing, and polishing applications
• Compatible with robotic and automated processing setups due to consistent conformability

Compatibility

Designed for use on bench grinders, pedestal grinders, and automated spindle equipment accepting a 1/2-inch arbor and accommodating a 6-inch diameter unitized wheel.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician. Power down and lock out the grinder or spindle motor before mounting or removing the wheel. Confirm that the arbor size and spindle speed rating of the machine do not exceed the wheel specifications before operation. Inspect the wheel for damage prior to each use and discard if any delamination or structural compromise is visible.
