The tool rest on a grinding wheel should be positioned ______ away from the wheel.

1/4 inch
1/2 inch
1/3 inch
1 inch

The correct answer is: 1/4 inch

The ideal position of the tool rest on a grinding wheel is crucial for both safety and effectiveness in operation. A distance of 1/4 inch from the wheel is generally recommended as it allows for proper support of the workpiece while minimizing the risk of the workpiece being caught or jammed between the wheel and the tool rest. This spacing helps to create a safe working environment by reducing the potential for accidents and promoting better control over the grinding process. Maintaining the tool rest at this specified distance ensures that users can achieve a balance between efficient grinding action and safety, preventing excessive wear on the grinding wheel and fostering an overall safer workplace.
