Extension Drifting Threaded Drill Rod for Mining and Quarry

ProDrill MF spherical extension rod with GT60 thread

GT60, the drill string factors attribute an entirely new thread design. In comparison with T51 rods, the forty% more substantial rod cross-segment of the GT60 rods gives 65%  greater bending stiffness and withstands the Affect-waves from the piston significantly for a longer time. So much so that the two drill-rod and shank adapter daily life can be doubled. As an extra reward, the more rigid drill string permits ideal drilling designs and higher costs of penetration.

Compared with EPT drilling tool methods, GT60 system permits a wider gap variety utilizing the same rock drill. Have been specially created for use with present day hydraulic leading hammers and are accessible in a equivalent selection to the regular Drill Rods. In addition GT60 Thread on 60mm Spherical materials.

It is frequent follow to bump up the push end of drifting drill steel for additional energy at the rock drill conclude to accommodate larger diameter and shank adapters. Drill steel of rock drilling tools is offered in several common lengths to match the drill feeds on a multitude of accessible drifting jumbos. A rock drill little bit diameter closer to the steel diameter can be used since the coupling does not enter the gap, this enhances flushing and gap precision.
Male/Feminine drill steel provides much more rigid connections and is easier to uncouple and manage. The service life also tends to be greater than with independent couplings. This is fortunate because the coupling stop are not able to be changed.

The advantages of drilling with M/F extension drill steel include: easy handling, a lot quicker uncoupling, tighter connections and the
prospective to drill straighter holes.

Utilized for both surface area and underground programs on more substantial hydraulic prime hammers, Prodrill’s Tubular Drill Rod Method feature Drill Bits, Shank Adptors and Male/Female Tube Rods available in T58 and T68 Threads with little bit diameters in the range 89mm-150mm(3 1/2″-6″)
Also obtainable are Xihu (We EPT Lake) Dis. Tubes to assi EPT in straight hole drilling on R32 via to T51 Threads, for holes in the dimensions range 54mm to 115mm.
