Saint-Gobain Abrasives' Norton brand has introduced Norton Vortex Rapid Finish Non-woven Right Angle Discs for the metal fabricating industry. The new discs feature an innovative, high-performance engineered grain and improved resin bond system providing aggressive, fast stock removal and a fine finish.
Vortex Rapid Finish discs are positioned as Norton's "best" choice for removing light welds and blending stainless steel, including removing weld marks and splatter, small flashings, parting lines; deburring and cleaning. The new discs prepare surfaces before coatings / plating, perform light cleaning and remove blemishes after welding stainless.
A very tight, unitized construction offers several benefits for deburring and finishing, as well as reducing cycle times. A thick nylon web gives Vortex Rapid Finish discs twice the life and the ability to do faster finishing with minimal shedding. A porous construction provides cool cutting and an improved cut rate. Vortex Rapid Finish discs are manufactured with a new curing process and bond technology to result in consistent performance from first contact to stub size for improved part quality with no smearing. The new discs offer excellent form holding, and will not break down under heavy deburring conditions.
"Vortex Rapid Finish discs provide maximum productivity with less downtime for changes, and can finish up to twice the number of pieces over conventional unified wheels," said Mr. David Long, Director of Marketing, Strategy and Marketing Information at Saint-Gobain Abrasives.
Norton/Vortex Rapid Finish Type 27 Depressed Center discs are available in sizes including 4 ½" x 5⁄8"-11" and 4 ½" x 7/8". The abrasive is an engineered aluminum oxide, grit size is 100-120 with a medium grade, and the type of backing is type 27/fiberglass.

abrasive
Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
- aluminum oxide
aluminum oxide
Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.
- backing
backing
1. Flexible portion of a bandsaw blade. 2. Support material behind the cutting edge of a tool. 3. Base material for coated abrasives.
- grit size
grit size
Specified size of the abrasive particles in grinding wheels and other abrasive tools. Determines metal-removal capability and quality of finish.
- parting
parting
When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.
- web
web
On a rotating tool, the portion of the tool body that joins the lands. Web is thicker at the shank end, relative to the point end, providing maximum torsional strength.
