The Gundrilling Handbook Forward

Making deep holes in materials ranging from wood, to plastics, and on to the toughest, most stubborn materials modern metallurgy has to offer has always held a deep fascination for me.

Understandably, there’s a lot of ground to cover in this book. I’ve attempted to structure the chapters in a manner which allows the reader to quickly navigate to the specific answers he’s seeking in a minimum amount of reading time.

Due to the diversity of the holemaking industry and specific individual holemaking requirements, the book attempts to be all things to all people.

Accordingly, you not only learn the intricacies of the approach which best fits your needs, but are further afforded a peripheral view into the available alternatives, and this can only justify and enforce your final choices.

If you’re already experienced in some phase of deep hole drilling, you’ll still come away the wiser, finding plenty of knowledge to improve your day to day drilling environment and learning a few good tricks along the way.

The individual chapters are structured in building block fashion. We begin with Part I., which starts with a History lesson. In the chapter on Applications, you get a handshaking acquaintance with where and how the process applies.

From there on we get into the nitty-gritty: Part II., ‘Putting the Gundrilling Process to Work’ gives you all the nuts and bolts stuff.

Part II. starts with a chapter on The Gundrill & Associated Tooling. Here we show not only the various configurations of gundrills available, but also the accessory tooling you’ll encounter.

Next we cover Process descriptions (Basic, and then CNC, and finally Conventional Machines), followed by Accuracy and Work holding, and then on to Oil and Coolant Selection.

After that comes an extensive chapter covering Parameters, which also includes a host of useful related information.

Finally, Troubleshooting & Tool Wear shows you how to get out of most of the predicaments you might reasonably be expected to get into.

Then on to Part III., which is aptly called ‘The Bonus Chapters’. This section covers Process Optimization, Tips & Tricks and a collection of actual Case Histories.

You might elect to read from beginning to end for an overall view, or, you can pick and choose the sections which apply to your immediate needs.

The goal of this book is to have a reference that will allow you trouble free deep and precision hole drilling.
