Finding the Ideal Belt Speed for Your 2x72 Belt Grinder

There is no single ideal belt speed for every grinding task. Select a speed within the operating limits of the complete grinder setup and the abrasive/attachment manufacturer’s guidance.

What affects the choice?

• Material and the result needed: stock removal, shaping, finishing or sharpening.
• Abrasive type, grit and the belt manufacturer’s recommendations.
• Contact-wheel or small-wheel diameter and bearing limits.
• Motor, drive-wheel diameter and available speed-control range.

A general grinding-speed example is not a recommendation for small wheels or sharpening. Lowering speed can be important for heat control, but pressure and the abrasive also affect the result.
