IADC 7 SERIES DRILL BITS
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.
Advantage:
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.
