For example, when grinding with a 4" (101.6 mm) wide superabrasive wheel, the rest blade will generally work well at 30º. But with a wheel width of 6" (152.4 mm) or 8" (203.2 mm), that same angle may generate too much pressure toward the grinding wheel and cause chatter. In this case, changing the angle to 20º or 25º will reduce the ...
