Drills, Taps & Dies
Workshop Practice Series #12
By Tubal Cain
103 p. illus.
Drilling true and correctly dimensioned holes and cutting accurate threads are basic requirements in all engineering work, but as in all areas of engineering new materials and new techniques lead to alterations in standards. Many of these are primarily concerned with production engineering and are well documented, but others affect the quite different requirements of the small workshop and the model engineer. This book does not only provide comprehensive tables of all the tools available or likely to be encountered but also explains the differences in various types of drill and thread form and their practical applications.
