About Drill Masters - Eldorado Tool Inc.

Drill Masters Eldorado Tool is one of the largest suppliers and manufacturers of deep hole gun drilling tools, fixtures, and accessories in the world. Our combined experience and resources offer the widest selection of in-stock deep hole gundrills and the greatest range of products, services, and experience proudly made and based in the United States. Add our rapid delivery and expanded customer service facilities, and it’s apparent why we’re the leader in gundrilling for parts, service, and innovative assistance.

Until World War II, there were no domestic manufacturers of gundrilling tools or machines in the United States. In 1948, this gap was filled when Eldorado Tool was founded to manufacture cutting tools and mandrels for deep hole drilling. As they were recognized for the quality of their work and innovation of their designs, Eldorado Tool was asked to design and develop tools for deep holes in a variety of metals used in a wide variety of manufacturing fields.

The company’s reputation and range of products grew through the 1950s, and in 1961, Eldorado Tool developed a full line of standard gundrilling machines. In the 1970s they became the first to introduce a complete line of deep hole drilling tools, machines, fixtures and accessories for the metalworking industry.

During this period, Drill Masters, which had originally been founded as a tool manufacturer, evolved into a respected supplier of deep hole drills and accessories for the automotive, aerospace, medical, firearms, and molding industries. Both companies developed customer demonstration and training lab facilities, then added gundrilling production services.

By the year 2000, Drill Masters and Eldorado Tool had become two of the leading designers and manufacturers of deep hole drilling tools, machines, fixtures, and accessories. Their experience and knowledge of deep hole drilling techniques in almost any material and configuration had made their products and services sought after by a wide range of industries throughout the United States and the entire world. The combining of these two leaders in 2002 has made Drill Masters Eldorado Tool one of the largest suppliers and manufacturers of deep hole drilling tools, fixtures, and accessories in the world.  Please visit our website at
