Located in Dover, Ohio, Allied Machine & Engineering Corp. (AMEC) was established in 1941 by Harold E. Stokey.

In 1966, AMEC began manufacturing Universal Style spade drills and holders, marking the beginning of an evolution in spade drill technological advancements. Allied developed and patented the Blade-Loc™ Feature for Universal Style spade drill holders, and introduced particle metallurgy CPM-M4 HSS to the spade drill industry.

The most significant breakthrough in the spade drill industry came in 1982 when AMEC introduced the T-A^® Drilling System. The unique geometry and state-of-the-art coating of the T-A^® drill insert revolutionized the spade drill industry as never before, thrusting Allied Machine & Engineering Corp. into a role of leadership through Research & Development of Engineered Drilling Solutions. In 1986, AMEC introduced TiN coated High Performance spade drills, a design that enabled end-users to obtain the benefits of the T-A^® Drilling System while allowing for use of the old universal holders. This opened the door for many to convert completely to the T-A^® for maximum benefits. In 1992, AMEC expanded into the European market and formed a limited partnership with Allied Maxcut Engineering Company of West Midlands, England, to ensure a high level of world-wide customer service.

In 2002, AMEC expanded into a new market by providing the exclusively ’in-house manufactured’ superabrasive Vitrified Grinding Wheels for customer applications. This superior design and quality is growing in popularity as more and more end-users discover the value of the AMEC optimum quality superabrasives.

New from Allied Machine & Engineering Corp. in 2004 is the GEN2-T-A™ drill insert… the next generation in hole making, engineered to provide an even lower cost per hole for the end-user.

ALVAN Expandable Reamers, Ring Style and Monobloc, Adjustable Chamfer Rings and MilSpec AccuPort Contour Cutters are also now available through AMEC.
