DTH HAMMERS GT Series
The New DTH HAMMERS Generation
The New OCMA DrillTech GT Hammer series are designed to reach higher drilling performance across some of the most challenging applications compared to the other Hammers on the market. Their considerable performance ensures that any drilling project is done in lower cost per drilling meter. The GT Series are built and designed for all drilling applications such as Waterwell drilling, Blasting holes / Quarry drilling, Geothermal drilling, Exploration and Construction drilling. The GT Series use Drill Bits without blow tube or foot valve “Tubeless Technology” and the robust shank with 12 spline reduces the wear when drilling in broken or softer ground.
Advantages and Innovations
Bit shank with 12 Spline and Hard Faced Chuck to optimize the Wear Resistance. The GT Series are designed to eliminates the blow tube/foot valve from the drill bit “Tubeless Technology”.
Hardened and Heavy Duty Wear Sleeve for optimum resistance in abrasive conditions and increase the Hammer life.
The robust no ported Piston design increases Impact Energy on Drill Bit and improves drilling Performance.
The GT Series DTH Hammers are equipped with “Choke System” that allows the driller to adjust the volume of air through the Hammer to optimize cutting evacuation when drilling under a column of water.
The Innovative Air Flow Chamber optimizes the air expansion and compression, by minimizing turbulence and reaching great Piston blow frequency, fast penetration rate and lower Air consumption that means lower fuel costs per drilling meters.
