Workshop Practice Series: No. 12 Drills, Taps and Dies

Workshop Practice Series: This is a good series of books covering most aspects of engineering practice, written by well known names in the model engineering world.   This book, written by Tubal Cain, not only provides comprehensive tables of all the tools available or likely to be encountered, but also explains the differences in various tyopes of drill and thread form and their practical applications.  One of the features of the book is a thorough examination of the correct size holes for thread tapping, which in itself could save the reader the cost of the book several times over, in the avoidance of broken taps.  Paperback.  Published by Special Interest Model Books.
