Foremost Dual Rotary (DR) drills have been working successfully around the world since 1979. Over the years, the DR method has earned a reputation for exceptional drilling performance in unconsolidated overburden. DR operators regularly drill and case through hundreds of feet of tough overburden where casing hammers and under-reamers have been unsuccessful. The Foremost DR also delivers excellent productivity for a variety of open-hole applications, making it a versatile, powerful and truly unique machine.
