Machinery's Handbook, Toolbox & Calc Pro 2 Combo

Great combo offer. Much cheaper than buying separately. Calculator is really handy with machining specific functions and information. I do d have to change the battery in mine just after I got it but they are a disposable item after all.

Great book and calculator. Pages a bit thin in the book. Overall still 5*

I have been after an 'Engineers Bible' for a long time and being an engineer the book is very useful to me in my day to day job.
