Product Description

deep rock well drilling

Wholesale rig’s drilling bit for the medium hard formations well

The description of IADC637 bit is TCI journal sealed bearing bit.It has gauge protection.It will be siutable for medium hard formations .The compressive strength is high.
The compressive strength are as following:
100-150MPA 14,500-23,000PSI
The formation will be used for hard, well-compacted rock such as granites,hard silica limestones,pyrite ores,quarzite streaks,hematite ores,chromium ores,magnetite ores and phosphorite ores.
Our factory can supply the TCI tricone bit and Steel tooth bit. The avariety of sizes is from 3 3/8″ to 26″ and covered most of all IADC code.

5 1/2″(140mm) Reverse Circulation TCI Tricone Rock 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.
