Remet Thread Hammer Well Drilling , Durable Borewell Drilling Hammers
Borewell Drilling Hammers Introduction
Accurate sampling Reverse Circulation (RC) drilling is gaining recognition and is already the most common mineral exploration drilling method used in many regions of the world. Combined with the Secoroc RC 45 hammer it is unbeatable for obtaining accurate and uncontaminated rock samples at high speed and low cost. SPM produces the complete RC drill string including hammer, bit and pipes, for both in-pit grade control and exploration drillers.
Reverse Circulation Drilling Hammers Key Features and Benefits:
. Patented mounting system for fixed internal components.
. An extremely sturdy shank with a short length allows for greater transfer of energy between the piston and bit.
. Variable chuck sleeve lengths for varying drilling conditions.
. Single piece sample tube assembly.
. Specially heat treated sample tubes over superior wear resistance vs. our competitors.
. Variable sample tube bore sizes allows the contractor greater flexibility in setting up his tool.
. Hardened wear sleeve for optimum wear resistance even in the most abrasive conditions.
. Multi-start threads on backhead and chuck ensure easy coupling/uncoupling of hammer.
. Metal sprayed chuck sleeve and wear sleeve options for greater wear resistance on outside circulation.
. All critical internal components are heat treated under strict control to maximize tool longevity.
. Ease of service with no special assembly or disassembly tools required.
