What is Mining Drill Bit?

Tricone bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.

Quality Control

In manufacturing, each process goes through an extensive and painstaking testing ,

quality control is a process that ensures customers receive products free from defects and meet their needs.

1, Raw material selection:To make a good drill bit, it is necessary to select the best material and gatekeeping the quality of the material. We purchase the high-quality steel and strictly control the material composition and size, it main includes the detection of the shape, diameter, reamed diameter, length composition, and flaw of the raw material, Tungsten Carbide and Grease are also the best raw materials on the market.Besides, we marked every different piece of materials before transferred to the warehouse.

2, In strict accordance with the ISO9001 international standards for production.

Carefully control every step of the production, complete each of the production process,

the production process is including blanking, forging, rough turning, heat treatment,fine turning, quenching, assembling, welding, painting, then storage.

Each working process was full inspected, after the qualification, then move to next working process, which to ensure the 100% qualified rate.

3, Sampling observation, numbered, packing and arrange the shipment.

AIDC5** Series Mining Drilling Bits Application

Soft to Medium-Soft Formation

Application: For use in less abrasive softer formations with compressive strength ranging up to 140 Mpa, such as shales, limestones, carbonates and most metamorphic formations.

Cutting structure: These bits are characterized by large diameter, widely spaced chisel or sharp conical inserts with high projection. This configuration promotes maximum penetration rates in softer formations. Smaller carbide inserts are provided on the gage and inner rows to contain shell erosion and improve performance.

  • Compression Strength: 15,000-25,000 psi
  • Drilling Speeds: 80 – 110 rpm
  • Jet Circulation: All sizes
  • Weight on Bit (WOB): 2,000 – 5,000 lbs/in of bit diameter

Advantage:

  1. Suitable for soft to extremely hard and abrasive formations.
  2. High temperature heat treatment forged alloy steel.
  3. Specifically designed tungsten carbide insert.
  4. Advanced synthetic grease improves bearing lubrication and reliability.
  5. Sealed bearing can improves bearing life for longer drilling time and more footage drilled.
  6. Tungsten carbide pucks added on the shirttail to protect against abrasive applications.
  7. Thread protected to prevent it damaged during transportation.
