3M 7100142496 Unitized Quick Change Wheel 2 Inch Ao

Product Description

The 3M 7100142496 is a 2-inch diameter unitized quick change wheel constructed with aluminum oxide abrasive on a non-woven, open-web substrate. It is designed for light-pressure surface preparation tasks including cleaning, blending, and finishing on flat or contoured workpiece profiles. The soft-density construction gives the wheel excellent conformability, making it well suited for work in tight areas or on parts with close dimensional tolerances. Machinists, fabricators, and metal finishing technicians typically use this wheel in angle grinders or die grinders equipped with a quick-change arbor system.

This wheel performs well on light deburring and edge radiusing operations on softer metals. The open-web, non-woven construction resists loading, which extends usable abrasive life compared to coated alternatives. It is particularly effective on smaller surface areas where control and finesse matter more than aggressive stock removal. Typical applications include aerospace, automotive, and general metal fabrication shops where surface finish consistency is required alongside tight part tolerances.

Key Features

• Soft-density non-woven construction provides superior conformability on contoured and flat surfaces
• Aluminum oxide abrasive mineral suited for blending, cleaning, and light deburring
• Open-web substrate resists loading, extending wheel service life
• Quick-change mount allows fast wheel swaps without additional tooling, reducing downtime
• Delivers controlled, consistent finishes where tight dimensional tolerances are required
• Suitable for light deburring and edge radiusing on softer metals

Compatibility

Designed for use with quick-change arbor-style angle grinders and die grinders that accept 2-inch diameter unitized non-woven abrasive wheels.

Installation Notes

Installation should be performed by a qualified metalworking technician or fabricator. Ensure the grinder or die grinder is fully powered down and disconnected from its power source before mounting or removing the wheel. Verify the tool spindle speed rating meets or exceeds the maximum RPM rating of the wheel before operation. Inspect the wheel for damage before each use and discard any wheel that shows signs of tearing or deterioration.
