This book has especially valuable information on making, hardening, and finishing all types of tools, including mills, drills, taps, reamers, dies, countersinks and more. It is a reprint of a 1907 book full of good how-to ideas. This book will show you how to treat the steel you are using in order to get the best results out of that piece.
Although the technology is old and needs to be used with good judgment there are lots of practical recommendations and useful ideas here.
