The newest edition of 'The Bible' in its field brings together volumes of knowlege, information and data gathered, revised and improved upon from experts throughout the mechanical industries.
Filled with typos, wrong answers, incorrect page numbers, etc. I was required to buy this book for a college course. It's on the opposite end of the spectrum when compared to Machinery's Handbook 30th. I gave this book away -@ no charge- to another poor sap that had to take the course.
As a machinist, the Handbook has been the quintessential reference for machining trumping even the internet. If you need to know the maximum diameter for a flathead screw in order to know how wide to make your countersink so the screw sits flush, then this book is for you!!!!
