The book is likely still under copyright (depending on the edition). McGraw-Hill or the Ostergaard estate may hold the rights. While older copies are sold used on Amazon or AbeBooks for $15–$50, a "free PDF" is often a scanned, low-resolution copy missing pages or diagrams. If you are working on a specific tooling

A plate designed to clear or "strip" the sheet metal stock off the punch after it completes its stroke and retracts. Strippers can be fixed (rigidly mounted to the die block) or spring-loaded (pressure pad style). Key Components of a Standard Die Set The
Based on the review, I would rate the book as follows:
Die making is the process of designing and manufacturing tools (dies) that cut or shape sheet metal. Unlike general machining, die making requires an intimate understanding of how metals behave under extreme pressure. A standard die assembly consists of two primary halves:
The completed die is loaded into a tryout press. A test strip is fed through, and a few sample parts are stamped. The toolmaker inspects the parts for dimensional accuracy, burrs, or deformation, making fine adjustments to the tool until it produces parts perfectly to print.
Punches holes or internal slots into a part. The material removed is the scrap (slug), and the remaining strip is the usable part. Forming and Bending Dies
