The Armor Drilling System from Vermeer is a single HDD tooling system with multiple drilling options designed to provide versatility and performance, and the integrated modular design allows the tooling to be adapted to various ground conditions. For soft to medium rock, shale, hard pan and caliched ground conditions up to 10,000 psi, use the Gauntlet bit. Carbide buttons are strategically placed on the bit for optimum cutting, and carbide hard facing helps to enhance wear and performance characteristics. A replaceable three-tooth design delivers a consistent cutting structure for steering corrections and maximum drilling performance. The Armor Drilling System is also available in 2- and 4-battery sonde lengths and is wire line compatible. 888.837.6337,
