API&ISO Tungsten caibid insert bit/Tricone drill bits/Rock roller bits /water well drilling equipmen/drilling for groundwater
1.Product description
Tricone bit is Widely used in borehole water well drilling,oil,gas well and mining projects.It mainly divided into steel tooth and TCI,diameter from 3 inch to 28 inch.
Generally,steel tooth tricone bit mainly used for soft rock formation drilling,our steel tooth tricone bit IADC code includes 126,127,136,217,etc.TCI tricone bit is mainly used
for hard rock drilling (rubber sealed bearing type) and very hard rock formation drilling (metal sealed bearing type),our TCI tricone bit includes IADC 437,517,537,547,617,637,
etc.
