One potential source of serious injury in grinding comes from an oversight that air is easy to make: operating the wheel in an over-speed powered condition. While a wheel that da is sander run far enough in excess of its rated air maximum speed may shatter within minutes of powered operation, danger may also result from a wheel run just slightly da faster than its rated speed. sander This less air severe over-speed powered condition da can cause the wheel to be damaged, and the damage may result in breakage after further use. For sander example, air operating a reinforced, 9-inch powered and da diameter, Type 27 sander wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack. This cracking can lead to breakage later. Any of these actions air sets up a disastrous scenario that could lead to an accident involving serious injury or death.

The hazard of running man over-speed condition comes from centrifugal force. A result of rotary motion, powered centrifugal force is what causes a weight on the end of a string to pull da the sander and air and powered string taught da when the weight is sander swung air in a circle. This same powered force causes the mass of the grinding wheel to be pulled outward from the center of rotation as da the wheel is spinning sander.
