Since 1951, Burr King has made belt and disc sanders that are primarily aimed at metal working. Their machines are very high quality and are scarce on the used machinery market.
Burr King Manufacturing was founded in 1951 by Don MacCarthy Sr. in East Los Angeles, CA. However, MacCarthy’s passion for belt grinders started long before that when he became the sole designer for belt grinders at Pacific Abrasive before leaving to start his own company.
In 1995, current CEO, Don MacCarthy Jr. took over the company and moved it to its current location in Warsaw, MO.
