As a factory, we specialize in Tricone Bits IADC537 4 5/8 (118mm) for optimal drilling performance. Get high-quality tools for your drilling needs from us.
API tricone rock roller bits in the stock from China factory is for drilling rig machinery Bit Description: IADC: 537 - TCI journal sealed bearing bit with gauge protection for soft to medium soft formations with low compressive strength . Compressive Strength: 85 - 100 MPA 12,000 - 14,500 PSI Ground Description: Medium hard and abrasive rocks such as sandstones with streaks of quartz, hard limestone or chert, hematite ores, hard, well-compacted abrasive rock such as: sandstones with quartz binder, dolomites, quartzite shales, magma and metamorphic coarse grained rocks. We can offer TCI bits in avariety of sizes (from 3 3/8" to 26") and all most of IADC codes.4 5/8 inches (118mm) reverse circulation TCI tricone drill bit with central jet hole. 1> Reverse Circulation is a special drilling process, the mud fluid is sucked from hole bottom to ground through central hole, rock chipes could be clear at higher rate than regular circulation. 2>This design of tricone bits has a central jet hole , rock chips could be circulated to ground inside drill pipe. 3>Reverse circulation is always used in drilling pebbles or sparse rocks, the ROP is higher than normal circulation. 4>The tricone rock bit with central hole could be used in both reverse circulation and normal circulation. Our advanced production lines, international standards (API Spec 7) and adequateinventory supports the drilling projects fordistribution of drilling tools professionally and perfectly. Our service fields: Oil & Natural gas,HDD & Construction ,Exploration,Mining,Water well , Geothermal ,Foundation ,Environmental.
