Allied Machine & Engineering has been solving holemaking challenges since 1941. Founded in Dover, Ohio by Harold E. Stokey, the business started small and grew through a relentless focus on engineering innovation. More than eight decades later, it remains family owned, with the third generation of the Stokey family now driving the business forward.

Allied is a leading global manufacturer of holemaking and finishing cutting tool systems, serving metal-cutting industries across automotive, aerospace, heavy equipment, defence, oil and gas, and renewable energy. The core proposition is straightforward: the lowest cost per hole, across the widest range of drilling, boring, reaming, threading, and burnishing applications.

The product portfolio spans several specialist brands. The T-A Pro® and GEN3SYS® XT Pro drilling systems set the benchmark for replaceable insert performance. Wohlhaupter® delivers high-precision boring tools engineered in Germany for high-volume production. Criterion® provides modular boring solutions for short-run flexibility. Superion® covers made-to-order solid carbide and PCD tooling. ThreadMills USA® rounds out the offering with an economical threading option. Together, they give customers a single, trusted source across every stage of the holemaking process.

Innovation runs through everything Allied does. From inventing the Blade-Loc technology in 1972 to launching the Insta-Quote® custom tooling system, the Allied Tool Academy and the ToolMD® 3D modelling platform, the company has consistently brought tools and technology to market that make life easier at the spindle.

Allied operates globally, with manufacturing and sales presence across North America and Europe, supported by an expert team of Field Sales Engineers who take technical knowledge directly to customers on the shop floor.

For manufacturers who need precision, productivity, and a partner who understands the application, Allied Machine & Engineering is the first call.
