What is the maximum distance a tool rest should be adjusted to prior to usage on bench and pedestal grinders?

The maximum distance a tool rest should be adjusted to prior to usage on bench and pedestal grinders is 1/8 inch. This measurement is critical for safety and performance when using these tools. By maintaining a distance of no more than 1/8 inch between the tool rest and the grinding wheel, you minimize the risk of the workpiece being caught between the wheel and the rest, which can lead to injury or damage to the tool. Additionally, proper adjustment helps achieve better control and accuracy during grinding. A smaller gap also reduces the likelihood of sparks or debris becoming a hazard during operation. Therefore, ensuring that the tool rest does not exceed this distance is essential for safe and effective use of bench and pedestal grinders.
