Portable Abrasive Wheel Tools

One of the most common tools found in any shop, the portable grinder is incredibly useful for grinding and finishing material of all shapes and sizes.

The hazards associated with portable grinders are similar to those of pedestal or bench grinders. The rotating abrasive stone can cause severe abrasions and cuts.
