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.

Advantage:

1. Strictly select the material to ensure the reliable quality. Bad steel and tungsten carbide inserts won't be used.

2. Strictly act according to the ISO9001 standard, and control by full-scale inspection.

3. Sales and support people are highly trained in the latest rock drilling technology and can offer you expert advice on what products will best fit a specific end use application.

Common fault analysis of Tricone bits

1. Early wear of the shirttail

Fault description: Abrasive formations, bent drill rod, seriously worn stabilizer and insufficient air for drilling rate attained etc, are all the causes which result in premature shirttail wear. In this case, the configuration of cones is good and the amount of inserts wear is small. Shairttail wear can also allow the big roller bearings to fall out resulting in bit failure.

Method: The designer should strength the shirttail with certain measures to increase the wear-resistance capacity of shirttails.

2. Early wear and loose movement of the bearing

Fault description: Excessive weight on bit, insufficent air to clean the hole and/or cool the bearing, leads to bearings overheating due to improper cooling and poor cuttings removal can shorten the service life of bit bearing.

Method: Reduce bit pressure and increase air pressure.

3. Cutting structure failure

Fault description: Excessive WOB or Rotation speed; Wrong bit selection; Cuttings blowing in bad conditions caused repeating crushing.

Method: Correctly select operating parameters and rotary types for specific working conditions

Bits thread are manufactured according to API standards.
