Wholesale API rotary rock roller rock drill bits in the stock from China factory 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.
We have two materials for the tricone bits, one material is Tungsten Caribde Insert bit , another material called Milled tooth or Steel tooth .The thread of IADC537 5 1/4" is 3 1/2 reg pin. It will be used for water well drilling, geothermal well drilling and grouting hole drilling. Sealed/Closed bearing can extend the working life.Tungsten insert gauge and protection on heel protecstcone body can let the bit work better. As drillers will consider the following factors druing the drilling job: 1)Working life of rock bit 2)Penetration rate of rock bits 3)Cost of drilling per meter/feet. It is important for the above details what the drillers care about, so we will improve our drilling bits.We will produce our bits as per the detailed drilling conditions. Our bits are exported more than 30 countries and serve the Oil and Gas,well and other industries Construction,Mining,Horizontal Directional Drilling(HDD),Geothermal and Environmental. | Basical Specification | |
