Multitool's patented design is the result of years of research by engineers who have specialized in belt grinding machinery.  It doesn't matter if you are a novice or seasoned metalworker, Multitool will help make all your projects look like you are a master craftsman. The Multitool belt grinder has five different working surfaces to cover any grinding, sanding, deburring, or polishing needs. Built to industrial standards to hold up to everyday use, the Multitool is a throwback to a time when tools were built to last!
