The belt sanders I have used before were not variable speed. I was just given a Porter Cable 352VS belt sander, that ranges from 850 SFM to 1300 SFM. The speeds are controlled by a dial ranging 1-6. What are the objectives of a variable speed belt sander? When and why do you want to use the high speeds or the low speeds? Thanks once again.

My guess is the slower speed would be for polishing the edges of glass or metal work. Some glass shops use hand held belt sanders especially in the field. For woodworking I would leave on the faster speed.

Thanks everyone. I'll never be using it on glass, just for wood. And then when my planer can't be used. The prime objective I had to use it for today, was for leveling out an end grain cutting board. I did not have the magic touch to level the board perfectly! Thanks
