Features of IADC7** series
Hard to Very-Hard Formation
Application :
For use in moderately abrasive consolidated formations with compressive strength ranging between 140 – 485 Mpa such as hard limestone, quartzite, granodiorite, and medium grade metamorphic formations
Cutting structure:
These bits are used to drill hard and abrasive formations. A more wear-resistant grade of tungsten carbide insert is used to prevent wear. Low cone offset with increased numbers of breakage resistant cutters add to the required bit durability.

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.
