Made in America since 1948.

Since its founding, the Eldorado name has been synonymous with gundrilling. Our machines are used in more shops around the U.S.A. than any other brand!

Ideal for companies that require maximum versatility, Eldorado gundrilling machines deliver unsurpassed performance and reliability within a compact footprint. Each machine incorporates flame-hardened and ground cast iron box ways with hand-scraped and fitted mating components (versus linear guide ways and milled surfaces). This results in superior vibration dampening and extended tool life.

Eldorado machines built-to-order


All Eldorado machines are built-to-order by Kays Engineering in our Marshall, Missouri facility. They feature high-pressure coolant systems, computer controls, and full machine enclosures. We design and manufacture all sub-assemblies in-house to ensure superior machine quality, performance, and durability that lasts for decades.
