Rockmore International adds ROK 250, DTH hammer to its range

Rockmore International is adding the ROK 250, a new 2inch class down-the-hole (DTH) hammer to its range at ConExpo-Con/Agg. The new addition to the broad range of Rockmore's high performance DTH hammer line is a breakthrough for DTH drilling technology, claims the company. “The ROK 250 model is considered to be the first 2inch class DTH hammer ever developed to operate under high air pressure levels up to 350psi (24bar) and beyond.

Rockmore’s new DTH hammer will work with the firm’s proven range of DTH bits
5087 Rockmore International is adding the ROK 250, a new 2inch class down-the-hole (DTH) hammer to its range at Conexpo-Con/Agg.

The new addition to the broad range of Rockmore's high performance DTH hammer line is a breakthrough for DTH drilling technology, claims the company.

“The ROK 250 model is considered to be the first 2inch class DTH hammer ever developed to operate under high air pressure levels up to 350psi (24bar) and beyond.  With a 2.6inch (66mm) wear sleeve diameter, the ROK 250 is designed to drill 3-3.5inch (76-89mm) diameter holes at high penetration rates.

"We recognised a niche market segment in the DTH drilling sector that could utilise higher air pressure input levels to improve hammer penetration rates and drilling performance for hole requirements as small as 3inches (76mm)," says Pejman Eghdami, executive vice president of Rockmore International.

“Our design team faced the arduous challenge of developing a compact 2inch class DTH hammer to withstand the technical demands of utilising higher input air pressure to produce exceptional hammer performance levels similar to larger high pressure rated models.”

The ROK 250, which incorporates the Rockmore SonicFlow technology to optimise airflow in the hammer, is said to exhibit excellent drilling performance in DTH applications for smaller diameter blast holes and construction projects that demand high drilling efficiencies and faster drilling rates by utilising larger compressors.
