A Complete Guide to HDD Rock Bits and Reamers Designed for the oil and gas industry in the 1970s initially, the designs of PDC bits have changed dramatically over the years to fit several other drilling industries including HDD. When working with HDD rock bits and reamers, it is important to remember that these are fast, durable, and steer easily in correct formations. A mismatch, thus, can affect the overall performance of a bit or a reamer significantly. Depending upon the number of blades, size of the cutters, and the blade angles, the designs of PDC bits vary greatly.
While a PDC bit with more number of blades can handle the harder formations well, it cuts slower in softer formations. PDC drill bits and reamers work exceptionally well in formations such as shale, sandstone, limestone, sand, and clay. The best thing about these is that while most
rock bits are only designed for harder formations, PDC bits work well in both soft and hard formations.
Some issues may arise when working with PDC bits if enough fluid is not being pumped to clear the cuttings out of the hole. Three-blade PDC bits vs. Four-blade PDC bits vs. Five-blade PDC bits vs. Six-blade PDC bits Three-blade PDC bits work well in very soft formations and the recommended PSI for these is 2,000 to 8,000 Four-blade PDC bits work well in very soft as well as medium soft formations and the recommended PSI for these is 6,000 to 11,000 Five-blade PDC bits work well in medium soft and medium hard formations and the recommended PSI is 8,000 to 20,000 Six-blade PDC bits work well in medium hard to hard formations and the recommended PSI for six-blade PDC bits is 15,000 to 30,000 This information about high performance drill bits and their designs is definitely going to help you choose the most suitable one among all the available options.
