Description
CUTTING STRUCURES
1. Tailored insert shapes and grades manufactured using state-of-the-art tungsten carbide technology for different formations having varied drillability and compressive strength,to provide an optimum match beteen inserts wear resistance and toughness.
2. By using computer simulation of the rock bteaking at the bottom of the hole,Shareat’s engineers are able to design the best inserts space to ensure the most balanced load on each insert.
3. Double rows of gage inserts For better maintaining full gage hole.
Cautions
· Please select the applicable formation and parameters according to the instructions.
· Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate.
· Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously.
· Bottom hole must be clean and bit must not be used for long section reaming.
· Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures
· The bit should be kept indoor with dry and well ventilated conditions at 10-33℃ and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.
New diamond Construction Machinery Co., Ltd. is a large-scale enterprise specializing in the production of deep-hole drills and cone drills. In many years of market operation, we have consistently adhered to the concept of "market-oriented" and "product-quality-oriented survival". My company's products, the use of conventional speed can withstand higher bit weight, with different cutting structures, can adapt to very soft to extremely hard formations. Indentation drill with high strength and high toughness alloy teeth, give full play to the high wear resistance inserts and excellent cutting ability. Steel tooth bit tooth surface welding new wear-resistant materials, extending the life of the drill.
