Drilling true, correctly dimensioned holes and cutting accurate threads are basic requirements in all engineering work. This book looks at this subject, and includes tables of all the tools available and explains the difference in various types of drill and their practical application.
This book has already paid for itself and my M1 tap has survived threading steel! Well written with plenty of humour, for 1976 I was relieved that metric gets equal footing amongst the dozen or so systems of measurement in this corner of engineering!
