What’s the difference between a Belt Sander and a Belt Grinder?
Are they synonyms or just similar? How about this one: truck…or pickup? Many would use these terms interchangeably, but growing up in the transportation world I recognize “truck” as an 18 wheeler capable of some serious work – 400 HP, 13 speeds towing 50,000 lbs! A pickup was great for grabbing lunch or loading up coolers and pulling a boat to the lake. Same goes for Belt Sander vs Belt Grinder →
A belt sander is useful when working with wood. The slower belt speed keeps heat from burning or glazing over the grain. Sanding is done by pressing the material against the belt which rides along a rigid backing platen. You feel the seam of the belt thump its way around and the drag of the belt robbing power. Typically much less pressure is presented to the belt with wood and therefore the belt tracking system is not as robust….a “pickup” if you will. You will find these from household name brands at at big box stores. But, if you want to get some serious “truck-like” work done on metal [mantra-pullquote align=”left|center|right” textalign=”left|center|right” width=”33%”][/mantra-pullquote] a high speed belt grinder is the tool for you. Belt speeds are typically 4,000-8,000 feet per minute resulting in rapid material removal. Plus, they are designed to use either the rigid backing platen or a rubberized contact wheel grinding surface. The rubberized backing behind the belt gives you butter-smooth feel and even quicker material removal. Hardcore fabricators will recognize names like Burr King, Multitool, or Grit. This high speed belt action allows much of the heat to leave with the grinding chips and dust, plus keeps the belt cool as it spins through the air. As you can imagine a Belt Grinder needs some serious HP and robust tracking system to handle the high pressure often placed against it. And typically the belt construction will consist partially of a Zirconia or Ceramic material on a heavy backing that can handle the rigors of steel removal.

Even some manufacturers will blur their product descriptions by using the terms sander or grinder too loosely. Just make sure you select the right machine with adequate power, speed, and of course long-lasting quality to get your job done right.
