Surface Prep Wheels and Surface Polishing Wheels - AA Abrasives Inc

AA Abrasives, Inc. has added a line of surface preparation and polishing wheels in both aluminum oxide - red/maroon and silicon carbide - grey. Both types of abrasive wheels are available in either a 4-1/2 x 7/8 or 4-1/2 x 5/8-11 arbor hole from stock.  These surface prep wheels are usually used after a Unitized Wheel.  The softer density allows for the surface prep wheels to conform to contours more easily. The surface preparation line is designed for blending, smoothing and finishing stainless steel, steel, aluminum and nonferrous metals.

How to Grind and Finish Stainless Steel with an AA Abrasives Dimple Wheel


AA Abrasives presents the Dimple Wheel. 

Grinding Wheel - The Dimple Wheel -AA Abrasives 40707
AA Abrasives AA-Flex Wheel aka The Dimple Wheel

The Dimple Wheel allows for one step grinding and finishing. These abrasive wheels are also known as the AA-Flex Wheel. They are constructed of aluminum oxide grains bonded to a strong, slightly flexible fiberglass reinforcing and have "dimples" on the grinding surface. AA-Flex wheels will remove stock much like a resin bond depressed center wheel and finish like a resin fiber disc. These flexible abrasive wheels are excellent for use on stainless steel and aluminum.



The Dimple Wheel is demonstrated here in a metal fabricating shop. The “Dimple” Wheel is used to grind and finish the surface of a stainless steel railing. The dimple wheel is used to create a smooth, uniform finish on stainless steel. This is a 4-1/2 x 1/8 x 7/8- A - Medium -Type 27 disc. The Dimple Wheel is used on a Metabo W8-115 angle grinder.
