Why is it dangerous to run an abrasive wheel faster than its recommended maximum speed?

Running an abrasive wheel faster than its recommended maximum speed is dangerous primarily because it could shatter into many pieces. Abrasive wheels are designed to operate at specific speeds for safety and efficiency. Each wheel has been engineered to withstand certain centrifugal forces at its maximum rated speed. When operated beyond this limit, the forces can exceed the structural integrity of the wheel, leading to catastrophic failure.

If the wheel shatters, it can send high-velocity fragments flying in all directions, posing serious risks to anyone in the vicinity. This not only endangers the operator but also anyone nearby, which is why adhering to the specified speed limits is critical for safety in any environment utilizing these tools.

While excess noise, motor burnout, and increased wear and tear are concerns that may arise in various circumstances, they do not present the immediate and severe dangers associated with the potential for an abrasive wheel to shatter when operated beyond its rated speed.
