Wholesale API TCI tricone drill bits with discounted price in the stock from China supplier for well drilling Bit Description: IADC: 637 - TCI journal sealed bearing bit with gauge protection for medium hard formations with high compressive strength. Compressive Strength: 100 - 150 MPA 14,500 - 23,000 PSI Ground Description: Hard,well-compacted rocks such as:hard silica limestones,quarzite streaks,pyrite ores,hematite ores,magnetite ores,chromium ores,phosphorite ores and granites. We can offer TCI bits in avariety of sizes (from 3 3/8" to 26") and all most of IADC codes.
Various hydraulic configurations ensure proper bit and hole cleaning in many applications. The nozzles can clean the heel and adjacent heel teeth.. Fewer bits per section, fewer trips out of the hole, and fewer days to complete your well decrease your cost-per-foot.| Basical Specification | |
