Numa Releases Range of HDD Drilling Systems
Perfect for hard rock and fractured ground formations
Numa, the world’s leading drilling technology provider, has released a range of HDD Drilling Systems designed for productive and efficient drilling in hard rock and fractured ground formations.
“Numa has a long history of serving the HDD market and with our range of HDD Drilling Systems we enhance our ability to serve our customers with the right products for the job,” said Numa President, Ralph Leonard. “Our high quality, Made in the USA HDD products provide the right balance of performance and dependability without sacrificing tool life.”
Numa’s HDD Drilling Systems consist of a variety of HDD components including hammers, bits, side load sonde housings, bent subs, and adaptors which are capable of drilling holes 4″ to 7-1/2″ (102 mm to 191 mm) in diameter. Some of the many benefits Numa touts for the HDD hammer line include: improved steerability, fast penetration rate, simplified field maintenance, reduced air requirements, and lower overall cost per foot.
With deep experience in rock drilling, Numa purposely designed their HDD hammers to drill longer in difficult rock conditions. Furthermore, a single bore design allows for a maximum bore diameter in conjunction with providing optimum life against abrasion. The full line of Numa’s HDD Drilling Systems is made up of the models indicated below with a full description on their website product page.
- HDD 35 for drilling holes 3-7/8” to 4” (98 mm – 102 mm) in diameter
