Established in 1941 by Harold Stokey, Allied Machine & Engineering Corp. entered the 1950’s as a job shop, manufacturing tapered bearing lock nuts and accessories. Allied introduced a more effective universal-style spade drill in the 1960’s, breaking new ground for the industry with patented developments in blade locking and particle metallurgy. In the 1980’s, Allied pioneered innovative spade drill geometry and coatings that took hole-making to a level never before seen by the metal cutting industry. In 1992, Allied formed a partnership with Allied Maxcut Engineering Company of West Midlands, England, enabling customers within the European markets to access the high quality Allied tooling and application support offered in the USA.
Today, Allied’s commitment to offering products of unparalleled quality continues to create value for our customers, our associates and our community.  Our focus remains constant: respect for those we serve, product quality and technical excellence, service to the customer, and maintaining the competitive advantage.
