3M 7100142228 Quick Change Disc 7 Inch Ao 5/8-11 Arbor

Product Description

The 3M 7100142228 is a 7-inch Quick Change Surface Conditioning XD Disc built for aggressive metal prep work on flats and edges. It uses an aluminum oxide abrasive bonded to a non-woven XD substrate with a stiff resin bond that supports consistent cut rates and edge durability through demanding applications. The quick-change arbor design accepts a 5/8-11 mount, allowing fast disc swaps without tools. This disc is intended for use by metal fabricators, welders, and finishing technicians who need reliable material removal and blending in a single step before applying final coatings or finishes.

This disc is suited for deburring, blending, and surface conditioning on ferrous and non-ferrous metals, stainless steel, and high nickel and chrome alloys. The open web construction responds to surface irregularities and reduces the risk of gouging the workpiece. It is a practical choice in fabrication shops, maintenance environments, and manufacturing settings where high contact pressure and controlled stock removal are required. The disc is available in brown coarse grade and maroon medium grade to match the application.

Key Features

• Aluminum oxide abrasive on XD non-woven material delivers high initial and extended cut rates on flats and edges
• Stiff resin bond maintains cut performance and edge durability under high contact pressure
• Open web construction responds to surface irregularities and minimizes gouging
• Non-woven substrate provides flexibility, long service life, and heat resistance
• 5/8-11 quick-change arbor allows fast disc swapping and improves tool efficiency
• Compatible with ferrous and non-ferrous metals, stainless steel, and high nickel and chrome alloys

Compatibility

Designed for use with right-angle grinders and other power tools accepting a 5/8-11 arbor interface, suitable for surface conditioning applications on ferrous and non-ferrous metals.

Installation Notes

Mounting and removal should be performed with the tool unplugged or the power source locked out. Verify that the tool arbor matches the 5/8-11 thread specification before mounting the disc. Inspect the disc for damage before each use and do not exceed the maximum RPM rating of the tool. Wear appropriate PPE including eye protection and gloves during operation.
