An improper feed rate. Slow down the rate of movement of the workpiece into the wheel. 3. The workpiece requiring quenching. Quench the workpiece in water to cool it.

Why does the wheel on my Shop Fox Grinder dull so quickly?
- A
  Alexis EvansSep 4, 2025
  If the wheel of your Shop Fox Grinder dulls quickly or grit falls off, it could be because: 1. You are applying too much pressure too quickly. Slow down the rate of movement of the workpiece into the wheel and use less pressure. 2. The wheel is too soft for the material being ground. Select a harder bond. 3. There is a bad wheel dress. Re-dress the grinding wheel. 4. There is defective wheel bonding. Replace the grinding wheel and consult the manufacturer of the grinding wheel.
