The maximum allowable gap between the face of the wheel and the tool rest on a pedestal grinder is

• A. 1/8 Inch
• B. 1/16 Inch
• C. 1/32 Inch
• D. 1/4 Inch

Answer: (A)

On a pedestal grinder, keeping the tool rest close to the wheel face is essential for safety. The gap should not exceed 1/8 inch, because a larger opening allows the workpiece or fragments to be snagged or pulled into the wheel, increasing the risk of kickback, wheel damage, or injury. A tighter gap helps guide the material safely and reduces the chance of it catching the wheel edge. The other options are either more restrictive than necessary, not practical, or clearly unsafe (a 1/4 inch gap is too large). So the maximum allowable gap that maintains safe operation is 1/8 inch.
