The 5A8 type grinding wheel is designed for internal grinding of roller bearings, setting holes, high-precision cutting tools (milling cutters, reamers), and for coordinate grinding of complex-shaped workpieces. It is used on snagging grinders, tool and cutter grinders, crankshaft grinders, and universal grinders.
Choosing a cylindrical shape reduces the weight of the grinding wheel and improves the center of gravity, increasing the rigidity of the grinder-wheel-workpiece system
