Belt Sander Size

The most commonly used belt sizes for belt sanders are:

  • 1 x 30 Grinders
  • 1 x 42 Grinders
  • 2 x 42 Grinders
  • 2 x 48 Grinders
  • 2 x 72 Grinders
  • 3 x 18 Grinders

Among these all, the most commonly used belt size for a belt sander is 3 x 21 but you can still choose another better option depending on your project size.

Belt speed

Not only does a single factor affect the speed of the belt in a belt sander. Several elements will cause the speed to change accordingly. These append the material being operated on, the grade of pebbles, etc. But still, keeping these all characters in an average, the normal speed is three thousand Surface Feet Per Minute (3,000 SFPM).

Other than this adequate speed, the buyer must know how to sustain discrete speeds for unalike stuff, grades, and in addition grains.


SFPM is abbreviated for Surface Feel Per Minute, which shows up the tempo of the belt horizontally with each foot per minute. The belt’s speed and cutting rate are directly proportional as the cutting rate will increase with an increase in the belt’s pace, and the fragmenting rate will decrease with the decrease in the sprint of the belt.

Every material has a different speed that will best suit it, and it can be calculated from the formula: SFPM = RPM x .262 x Tool diameter.

For instance, if the measurements of the belt for your belt sander is 3 x 21 with a motor of 2100 RPM with a 6″ drive wheel, the speed can be calculated as (2100 x .262) x 6″ = 3,301.2

So you can calculate the speed rate for your sander’s belt by using this formula. There is an average table that you can check from websites showing you the whole table of speed for variant statistics such as those for plastics is 1920 to 3540 and those for timber is 2940 to 4920.
