How To Choose The Right Drilling Tools

The article is writting to teach you how to choose the right drill tools.

The content covers the following tools:pilot adapter,guide tube and guide rod,drill pipe without undercut,rubber collared rod,forge collar rod.

1.Why  do we sometimes choose pilot adapter with insert instead of usual pilot adapter ?

2023 11 15 142448pilot adapter with insert

The insert in pilot adapter could be made of various materials(such as hard alloys),may have many different shapes or cutting strucures,catering to rock formation and specific driling require.Inserts can improve the adapters’ durability and drilling effiency by allowing easy replacement without changing the entire adapter.

To sum up,Pilot Adapters with Inserts offer greater customization and flexibility by allowing adjustments based on specific drilling needs. Adapters without Inserts are simpler and suitable for regular drilling but might lack the flexibility of their counterparts with replaceable inserts when needing to adapt to varying conditions. The choice between these adapters depends on specific drilling conditions, requirements, and the anticipated geological conditions.

2.How do guide tube and guide rod work?

[fusion_table fusion_table_type=”1″ fusion_table_rows=”” fusion_table_columns=”” margin_top=”” margin_right=”” margin_bottom=”” margin_left=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” animation_type=”” animation_direction=”left” animation_color=”” hue=”” saturation=”” lightness=”” alpha=”” animation_speed=”0.3″ animation_delay=”0″ animation_offset=””]

AppearanceDesignFunction
Guide tube2023 11 15 145114The guide tube is typically a tubular component mounted above the top hammer on the drill string.Its primary function is to provide a fixed pathway, allowing the top hammer to move vertically within the borehole. It aids in ensuring the top hammer travels along the correct path, maintaining borehole accuracy and stability.
Guide rods2023 11 15 145209Guide rods are rod-like components installed between the drill string and the top hammer.They help prevent the top hammer from deviating from the intended borehole path, maintaining borehole accuracy.

To sum up, the guide tube provides a fixed pathway for the vertical movement of the top hammer, while guide rods offer additional support and guidance within the drill string to ensure the top hammer maintains a stable linear motion. They differ in positioning, installation, and their specific role in stabilizing and guiding the top hammer during drilling operations in a Top Hammer system.

[/fusion_table]

3.The difference between dill pipe with undercut or without undercut.

2023 11 15 151921

Drill pipe with undercut has grooves and notches at the connection end,creating a recessed edge.The design offers increased surface area at the connection end,providing more gripping surfeces and enhance drill pipe’s strength and stability.These are often utilized in more complex drilling tasks or applications that involve greater torsional or tensile forces.

In summary, a drill pipe without an undercut is used in basic drilling tasks, while one with an undercut is employed in more demanding operations where enhanced strength and stability at the connection point are required due to higher forces encountered during drilling.

4.The difference between rubber collared rod and forged collar rod.

The forged collar rod is more strength,durable because of forging technology,it often preferred in heavy-duty drilling applications where greater strength and rigidity are required.

The rubber collar serves as a shock absorber and sealant between the connected drill rods which  helps prevent drilling fluids from leaking out of the joint.

Threaded Button Bit: Can It Be Reused?

The threaded button bit is a tool used in rock or soil drilling, which is often used in exploration, geological drilling, water well drilling and other fields. Because of the high hardness of rock or soil, the drill bit is easy to break and wear during use, so it breaks easily.

The service life of threaded button bit is affected by many factors, such as hardness of rock or soil, service frequency and service mode and so on, Under normal conditions, the use of threaded button bit in dozens to hundreds of times, can not be used for a long time, and need to be replaced in a timely manner.

343

In order to improve the service life of the threaded button bit, the following methods should also be taken.

Reasonable selection of button shape of threaded button bit.

  • The correct choice of button shape of threaded button bit can not only prolong the service life of the bit, but also increase the piercing speed and reduce the piercing cost. The selection of the button shape of the bit is mainly based on the physical and mechanical properties of the ore, as well as the compressive strength, hardness and drillability of the rock. In addition, the diameter and water content of the bore hole and the technical performance of the rotary drill should be considered.
  1. When drilling in hard rock formation, we usually use the threaded button bit, because the button of the bit protrude shorter, but the distribution of button is more dense, can withstand greater axial pressure, suitable for drilling in extremely hard and wear-resistant ore rock.
  2. If perforating in soft rock formation, we usually use bit with long and sparse button, which is suitable for perforating in soft rock and plastic rock.

  If they are not used properly, the button bit will be used in soft rock drilling, although the starting life is long, but the drilling speed is very low. After taking into account the drilling costs, the total drilling costs are higher. Conversely, if a wedge-toothed drill is used to bore in extremely hard and wear-resistant ore, the alloy teeth will soon wear out or break. Therefore, reasonable selection of bit tooth shape can improve the service life of the bit.

  • The drilling speed of the bit, the physical and mechanical properties of the rock being drilled, the axial pressure exerted on the bit, the rotary speed of the drilling tool, the torque of the bit, the shape of the teeth of the tooth and the number of teeth taking part in crushing the rock at the same time, and the amount of Compressed air being blown through the holes. According to the rock crushing mechanism of the drilling hole, the main parameters of the drilling system are axial pressure, rotary speed and slag discharge air volume.
  1. Effect of axial compression on bit life.

In order to break the rock effectively, it is necessary to apply enough axial pressure to the bit, so that the stress caused by the tooth of the tooth is enough to overcome the compressive strength of the rock, but there is a reasonable value in the axial pressure applied to the bit, neither too big nor too small. When the axial pressure value exceeds a certain degree, the axial pressure then increases, the piercing speed does not increase, the axial pressure is too large will also cause the fracture of cemented carbide teeth or make the bit bearing damage.

2. The influence of rotary speed on bit

In a certain range, the drilling speed of the roller drill increases with the increase of the rotary speed of the drilling tool, but if the rotary speed is too high, it will not only make it difficult to discharge slag at the bottom of the hole, but also produce strong vibration, affect bit life.

The rotation speed of the bit must ensure that the teeth of the cone have enough contact time with the rock, in order to reach the effective volume of rock  fragmentation, in the hard rock, with the increase of the rotation speed, the impact load increases, the wear of tooth and bearing of the gear is obviously increased, therefore, the use of high speed is limited. But when the rock is soft, it usually adopts the working state of high rotational speed and low axial pressure.

       3.Influence of air volume of ballast discharge on bit life

The volume of air discharge directly affects the service life of cone bit. With the increase of air flow, the rock debris at the bottom of the hole can be effectively blown and the rock crushing condition of the teeth can be improved. At the same time, it can reduce the wear of the claw back, and can better cool the cone bearing and prolong the life of the cone. In addition, the hole bottom debris can be reduced and the effective hole depth can be increased.

However, it should be pointed out that the smooth discharge of rock debris at the bottom of the hole depends mainly on the air-back velocity, which is influenced by the air volume and the annular space between the drill pipe and the hole wall. Therefore, when considering the effect of ballast discharge, can not simply pursue the capacity of air compressor. Not only can achieve a good ballast removal effect, but also to reduce unnecessary air consumption.

In short, although the button bit can not long-term re-use, but can be through maintenance and maintenance measures to extend its life, reduce the number of replacement, saving costs. When using threaded button bit, it is necessary to protect bit, clean and store it in time, and follow the correct way to ensure drilling effect and safety.

  • Top hammer threaded drill bits are significant component of mining and construction industries for drilling technology in rock surfaces. One of the most common is button bits design and are ideal for drilling through hard and abrasive rock surfaces. Cross bits are suited for drilling through soft and medium-hard rock surfaces, the cross bit also adopts mature technology, high-quality steel and alloy, has strong radial wear resistance, maintains high production efficiency and can control the cost. Chisel bits, on the other hand, are used for drilling through hard rock surfaces and ideal for drilling straiht holes, its main characteristics are fast opening speed and easy to control the depth and angle of channel and iron hole. The maintenance of iron hole mud bag is simple and saves manpower.

  • For the top hammer threaded drill bit what drilling different rock formations,  is also very particular about the face design. The face design means the shape and placement of the buttons or carbide inserts on the bit. Let me give on instance: hard an abrasive rock formations usually use a conical button, while a flat button face design is ideal for soft rock formations. Certainly the spacing between the buttons or carbide inserts also affects the performance of the drill bit.
  • Maintaining rock drill bits is crucial to ensure their longevity and performance, inspect the bit regularly to check for any signs of damage such as cracks, worn-out buttons or cones, or excessive wear. If any of these signs are present, it may be time to replace the bit.Inspect the bit regularly to check for any signs of damage such as cracks, worn-out buttons or cones, or excessive wear. If any of these signs are present, it may be time to replace the bit.When not in use, store the bit in a dry and cool place, away from direct sunlight and moisture.

Choosing the right top hammer threaded drill bit is crucial for the success of your drilling order. Combine the above factors,it’s very important for the choice design, size, and face design, you can select the best drill bit for your project. Witch the right drill bit you can achieve efficient drilling, save your time and money and ensure the safely of your project.
