3M 7000047133 Convolute Finishing Wheel 8 Inch Ao

Product Description

The 3M 7000047133 is a dense, stiff convolute abrasive finishing wheel built for final-finish work on a range of metal surfaces. Constructed with an open-web aluminum oxide abrasive, it delivers high cut rates at low contact pressure, reducing operator fatigue during extended use. The rigid convolute construction holds its shape well, making it effective on flat surfaces and sharp corners alike. Weighing 4.1 pounds, this 8-inch diameter wheel is sold individually and is well-suited for bench grinder or finishing machine applications in fabrication and metalworking environments.

This wheel is used in metal fabrication shops, welding operations, and light manufacturing settings where consistent satin or antique surface finishes are required on ferrous and non-ferrous metals. The open-web design resists loading, extending abrasive service life compared to solid-constructed wheels. The wheel can also be dressed to conform to specific part geometry, making it adaptable for contoured or irregular workpieces. Licensed tradespeople and skilled fabricators in both production and job-shop environments commonly specify this type of wheel for pre-finishing and decorative finishing operations.

Key Features

• Dense, stiff convolute construction performs reliably on flat surfaces and corners
• Produces satin and antique finishes on a variety of metals
• High cut rate requires low contact pressure, reducing operator fatigue
• Open-web design is load-resistant, prolonging wheel service life
• Can be dressed to fit specific or irregular part geometry

Compatibility

Designed as a standard replacement-style convolute finishing wheel for bench grinders and finishing machines that accept 8-inch diameter wheels.

Installation Notes

Mounting and use of abrasive wheels should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Inspect the wheel for cracks or damage before mounting. Ensure the machine spindle speed does not exceed the maximum rated RPM marked on the wheel. Always install the appropriate flanges and guards before operating.
