Your college library fee is already paid. Most engineering libraries have 10+ copies of this book in the "Reserve Section." You can either borrow it for a semester or make high-quality photocopies of specific chapters (which is legally permissible under "fair use" for education).
Instead of searching for a risky "free PDF," consider these legitimate, low-cost options:
While Volume 1 of the Hajra Choudhary series focuses on basic workshop practices (carpentry, fitting, smithy, forging), Volume 2 elevates the discussion to machine tools and production technology.
Here is what makes this volume unique:
To convince you why this book is worth buying or borrowing legally, here is a typical syllabus covered in Workshop Technology Vol 2 (Hajra Choudhary) :
