Product details

Kingdrilling Single construction tricone bits are suitable for the pipe jacking system which can dig the pebble formation, soft formation, medium hard formation, hard formation. Due to the unique cutting process parameters design, inserts profile and amount of the insert, cutting angle, inserts distribution, cutter shape, etc. can guarantee each row of the insets' highest cutting efficiency and movement direction precisely, to make the broken area and volume be the largest when each insert contact thole hole wall, to ensure efficient tunneling speed. Simultaneously the unique patented sealing structure design and vacuum oil injection technology, ensure the effective use of bearing life lengthen 35%. According to the need for personalized design, to make the roller cutter meet carious types of rock with 10MPa to 250MPa.
