6 3 / 4 " ( 171mm ) IADC 532 TCI Tricone Drill Bit Top Grade Long
Serve 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.
Product features:
Tungsten carbide insert bit, TCI bit, button bit Sizes range from 3
7/8" to 26" .
