The Book of Grinding

About the Book

The Book of Grinding is 2000 pages of detailed, practical, down-to-earth information on grinding, developed over 15 years by Dr. Badger. Attendees to Dr. Badger’s courses receive an electronic copy of the book, now in searchable pdf format.  Subjects covered are given below.

The Book of Grinding is presented in a straightforward, easy-to-understand format. Complicated concepts in grinding theory are translated into practical terms. Equations are given in simple format with units. This is the best literature currently in existence on the subject of grinding.

A sample of pages from The Book of Grinding can be downloaded here, in pdf format.

Materials Included

The Book of Grinding includes a free CD of The Grinder’s Toolbox®.


The Book of Grinding is currently only available to attendees to one of Dr. Badger’s courses. In July 2015 it will be available for purchase with an audio narration. However, to receive the full benefit, Dr. Badger strongly urges people to attend one of his courses.

The Grinding Doc talks about grinding literature and The Book of Grinding in his award-winning CTE
video series.
