How far away should the tool rest be on a pedestal grinder?

• A. 3 millimeters or 1/8 inch
• B. 1 centimeter
• C. 5 millimeters
• D. 2 inches

Answer: (A)

The key point is to keep the tool rest very close to the wheel so you can guide the workpiece with solid support and minimize the chance of the stock being pulled into the wheel. The safe, practical distance is about 3 millimeters (1/8 inch). This small gap lets you control the workpiece while still allowing the wheel to bite properly. If the gap is larger, the workpiece can jam or shift, increasing the risk of wheel pinch, kickback, or loss of control. If it’s too close, it can rub or contact the wheel, causing wear or heat buildup. So aim for roughly 1/8 inch.
