You must mount Type 1 cutting-off wheels between flanges that are:
(1) Properly relieved with matching bearing surfaces;
(2) At least one-quarter the wheel diameter.
Note: | American National Standards Institute (ANSI) B7.1-2000, Safety Requirements for the Use, Care and Protection of Abrasive Wheels, has specific exemptions for some reinforced, bonded abrasive cutting-off wheels and steel centered, diamond cutting-off wheels. These wheels are primarily used for masonry cutting and concrete sawing. |
