The Roughneck R600 is the largest of the company’s pneumatic percussion drilling systems for use in HDD applications.
Designed for drilling solid rock with bit diameters of 7.25 to 8 inches, the R600 gives HDD contractors the ability to complete larger-diameter bores in fewer passes, as well as access to a wider range of single-pass boring applications, Hammerhead says. The larger bits driven by an R600 also increase the range of single-pass applications the driller has access to, such as in communications and or other service installations. The R600 joins the R400, designed for 5.25-inch straight and offset bits, and the R500, for straight and offset bits to 6.25 inches in diameter.
