Paper presented at the IADC/SPE Drilling Conference, New Orleans, Louisiana, February 1992. doi: https://doi.org/10.2118/23937-MS Download citation file: Ris (Zotero) Reference Manager EasyBib Bookends Mendeley Papers EndNote RefWorks BibTex ABSTRACT The LADC (International Association of Drilling Contractors) roller bit classification system provides a convenient method for categorizing rock bits according to their design features and intended applications. The system has been used worldwide since 1972. The 1992 version includes improvements which reflect the latest design trends in roller cone bits.This paper explains the IADC roller bit classification code. Current classification charts are shown for major bit manufacturers. The relationship between the LADC code, bit design factors, and operating guidelines is discussed. Examples depict the major design features included in the code.Since this version contains only minor changes from the 1987 Roller Bit Classification System,1 these changes will be listed at the beginning of the paper. Those experienced with the code need only read the changes. Subsequent paragraphs present a complete discussion of the classification system for the benefit of the readers who may not be familiar with the system or who wish more detail. IADC bit topics also updated in 1992 include Fixed Cutter Classification2 and Dull Bit Grading.3,4 Copyright 1992, IADC/SPE Drilling Conference You can access this article if you purchase or spend a download.
