Product Description
8 1/2" IADC537N tungsten carbide insert bit

TCI (Tungsten carbide insert) bits are a great harder formation or simply hard formation drilling tool. As the formation's do differ from one location to the next, these bits come in many shapes and sizes having multiple features and cutting structures to combat downhole diversities you may encounter. We keep a generous inventory on hand ranging from 3-7/8" through 26" and can provide larger sizes on request. These bits are typically sealed bearing. All come with regular API connections. These bits feature 3 or 4 jet ports, the 4th being an optional center jet. We house all jet sizes to meet your TFA (Total Flow Area) requirements. These bits are used in the oil, gas, and water well industries. <o: P>
