Book excerpt: This completely updated volume covers the design, manufacturing, and inspection of high‐productivity drilling tools (HPDT) and addresses common issues with drilling system components. It discards old notions and beliefs as it introduces scientifically and technically sound concepts and rules with detailed explanations and multiple practical examples. High‐Productivity Drilling Tools: Design and Geometry introduces the development of the concept of high‐productivity (HP) drill design and its manufacturing and application features. This book continues to develop the concept of a drilling system in the new edition and includes new practical examples. It explains how to properly design and manufacture drilling tools for a specific application and includes a detailed explanation of the design features, tool manufacturing and implementation practices, metrology of drilling and drilling tools, and the tool failure analysis. Using the coherency law as the guidelines introduced in the first edition, the new edition shows how to formulate the requirements for the components of the drilling system, pointing out that the drilling tool is the key component to be improved. This practical book should be on the shelves of all industrial engineers, those working in production and manufacturing, process designers, tool material designers, cutting tool designers, and quality specialists. Researchers, senior undergraduate students, and graduate students will also find this book full of very helpful reference information. This book is also available as a set - Drills: High-Productivity Drilling Tools, 2-Volume Set (9781032203508).
