To convert meters per second (m/s) to SFPM: m/s x 196.85 = SFPM. To convert SFPM to m/s: SFPM/196.85 = m/s. To convert RPM to SFPM: Wheel Diameter x RPM x 0.262 = SFPM
NORTON OFFERS YOU A NO RISK TEST POLICY! To verify the superiority of our products, we invite in-plant testing against any other brand of abrasive products, or lower performance tiers of our own products. This makes it as easy as possible for you to see the time-, labor- and money-saving advantages of Norton products. And it also allows you to test the many new products in our catalog. You have absolutely nothing to lose and everything to gain by conducting an in-shop test. Contact your local Norton Distributor to arrange for an in-plant, no-risk product test. 1 The test will be conducted in your own shop, on your machines, using your own workpieces. 2 If the Norton product tested proves completely unsatisfactory, you will receive a full refund. 3 If the Norton product tested performs at a lower level than the product presently being used, you will receive an adjustment to make up the difference in performance. 4 YOU ARE THE FINAL JUDGE OF PERFORMANCE! SAINT-GOBAIN IS COMMITTED TO BEING A COMMUNICATIONS AND ENVIRONMENTAL LEADER 24/ 7 Online Information Along with an updated, easy-to-navigate look, the Norton web site continues to evolve in order to provide fuller content with enhanced product information and application solutions. Our goal is to tie our printed materials more closely with our electronic tools so that finding what you need is simple and productive. Our product search catalog will become more interactive with links to safety tips, MSDS sheets, photography, case histories, etc. www.nortonabrasives.com Just like our product innovation, we are also dedicated to being a leader in green practices. As we transition to more electronic communications, our aim is to enhance the speed of information to you, allow you to print on demand just what you need, and give you more online tools to find the products and solutions for the application at hand.
