IADC 517 TCI Rotary Drill Bit tungsten inserted Drill Bit for Oil gas mining
IADC Code Classifications
STEEL MILLING TOOTH BITS
IADC 1 SERIES DRILL BITS
These bits are used to drill low-compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hardfacing is used to control tooth wear. On the softest bit types this hardfacing completely covers the bit teeth.
STEEL MILLING TOOTH BITS
IADC 1 SERIES DRILL BITS
These bits are used to drill low-compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hardfacing is used to control tooth wear. On the softest bit types this hardfacing completely covers the bit teeth.
IADC 2 SERIES DRILL BITS
These bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hardfacing is applied to reduce tooth wear.
IADC 3 SERIES DRILL BITS
These bits are used to drill hard and abrasive formations. Very short, closely spaced teeth with minimum amounts of hardfacing are used for breakage resistance. These bits must withstand high loads and drill abrasive formations with a crushing, cutting action.
TCI (TUNGSTEN CARBIDE INSERT) BITS
IADC 4 SERIES DRILL BITS
These bits are used to drill low compressive strength, very soft formations. The bits maximize the use of both conical and chisel inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, results in high bit penetration rates. The deep intermesh of cutter rows prevents bit balling in sticky formations.
IADC 5 SERIES DRILL BITS
These bits are used to drill low compressive strength, soft to medium soft formations. Drill bit design features are used to enhance bit penetration rates. Some reduction in cone offset and insert projection is used to improve cutter durability. Insert numbers and pitch is controlled to prevent tracking.
IADC 6 SERIES DRILL BITS
These bits are used to drill high-compressive strength, medium hard formations. A small amount of cone offset and low insert projection is used to prevent cutting structure damage when hard streaks are encountered. Increased numbers of blunter, smaller diameter inserts are used to increase life in harder, more abrasive formations.
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.
IADC 8 SERIES DRILL BITS
These bits can be used to drill extremely hard and abrasive formations. Wear-resistant inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.
The soft formation TCI tricone bits are used to drill low compressive strength, very soft formations. This bit maximized to use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, results in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
Medium formation TCI tricone bits:
The medium formation TCI tricone bits features aggressive chisel
tungsten carbide inserts on the heel rows and inner rows. This
design provides a fast drilling rate and added cutting structure
durability in medium to medium hard for mations. The HSN rubber
O-ring provides adequate sealing for bearing durability.
Hard formation TCI tricone bits:
The hard formation TCI tricone bits can be used to drill hard and
abrasive formations. Wear resistance
tungsten carbide inserts are used in the outer rows to prevent loss
of bit gauge. Maximum numbers of
hemispherical shaped inserts are used in all rows to provide cutter
durability and long life.
Medium hard formation TCI tricone bits:
The medium hard formation TCI tricone bits features robust chisel tungsten carbide inserts on the heel row
and conical on the inner rows. This design provides a fast drilling
rate and added cutting structure durability in medium to medium
hard formations. The HSN rubber O-ring provides adequate sealing
for bearing
durability.
