Description

First published in 1915, this volume contains a detailed treatise on drilling and tapping operations, including chapters on the design of drill jigs and fixtures intended for interchangeable manufacture. Drilling is creating a smooth hole in a material using a drill and motor, and Tapping refers to the action that produces a thread on the inside of the hole. Written in clear, simple language and containing useful diagrams and tables, this volume will prove to be an invaluable resource for anyone with an interest in drilling and related subjects. Contents include: "Principles of Drilling Practice", "Types of Drilling Machines", "Tapping and Tapping Attachments", "Grinding Twist Drills", "Drilling Department Equipment and Requirements", "Deep-Hole Drilling", "Principles of Jog Design", "Jog Bushing", "Locating Points and Adjustable Stops", "Jog Clamping Devices", "Design of Open Drill Jigs", etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
