The new abrasive blade from Norton makes it possible to use a single, high-speed cut-off wheel with a 1-inch or 20-mm arbor hole instead of two wheels with different arbor-hole sizes for heavy-duty, high-speed cutting. Three layers of full glass cloth add extra reinforcement and strength to make the blade last longer. The blade's heavy-duty bond with triple reinforcement is designed to resist side pressure and result in longer life. The new blade is available in 12-, 14- and 16-inch sizes. www.nortonabrasives.com/
