How to Buy the Best Belt Sanders

How a Belt Sander Works

Belt Sanders are built to provide superior speed, force, and strength to a flat surface to produce and smooth finished sanded outcome. There are 4 primary features that every belt sander has in order for it to operate correctly.

  • The drums – There are 2 drums, a front and back drum in which the sanding belts wrap around.
  • Back Drum – The back drum is driven by the belt sanders motor.
  • Front Drum – Rotates freely allowing the sanding belt to rotate around and between the 2 drums.
  • Belts – This is the specialized sandpaper that is wrapped around the drums that allow the tool to sand the surface. The belts come in various sizes and grits depending on the belt sander and the job you are trying to complete. Belt size is usually in the description of the model you are viewing (i.e., Makita 9031 1-1/8” x 21” = 1/8” x 21” is the belt size)
  • Motor – This is the driving force to the back drum that allows the belts to rotate.
  • Speed – This option will vary depending on the tool
  • Constant – this means it has only 1 speed
  • Variable – multiple speeds allow the tool to adapt to the project you are working on.

When to Use A Belt Sander 

Belt Sanders are typically used for large surfaces that requires a smooth sanded finish so that a stain or lacquer can be applied. Using a belt sander instead of manual sheets or other similar tools can save a pro upwards of hours of time during a project.
