What is the recommended distance for a tool rest from a bench grinder wheel?

1/2 inch
1/4 inch
1/8 inch
1/16 inch

The correct answer is: 1/8 inch

The recommended distance for a tool rest from a bench grinder wheel is 1/8 inch. This specific distance is critical for safety and efficiency during operation. When the tool rest is positioned too far from the wheel, it can lead to instability when grinding, making it difficult to control the tool and increasing the risk of accidents. Conversely, if the tool rest is positioned too close, there is a greater chance of the tool contacting the wheel, which can cause kickback or damage to both the tool and the grinder. The 1/8 inch distance strikes a balance, allowing the user to maintain proper control while minimizing the risk of the tool slipping or being damaged. It is also essential to regularly check and adjust the distance as the grinding wheel wears down over time, ensuring optimal safety and performance during use.
