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:

High quality----strictly act according to the ISO9001 standard, and all bits are manufactured according to strict standards, set forth by the American Petroleum Institute (API).

Propessional Equipment---- No matter raw material selection, or processing technology are selected is the industry leading technical equipment.

16 Years History---- From 2003 to 2019, customers are located all over the world and win a good reputation.

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.
