While I have three copies of Machinery's Handbook, two printed and one digital, and I use them often, I do find things that they lack.
Recently I purchased a copy of Engineers Black Book. It comes in Inch and Metric versions but the Inch version has included metric numbers in most of the tables where it makes sense to do so. One particularly nice pair of pages that face each other when open is the actual size chart of gear teeth sizes, one DP and the other Module. They are arranged so that the closest sizes of each type are side by side on the two pages. This provides not only a handy way of checking on the pitch of the gear teeth, but also a back and forth reference between the two series of pitches. Mind you, this is not to say that there is an exact equivalence between the similar sizes: they are only close, not exactly equal. It also has a number of practical shop types of information like drill bit geometry for various materials and lathe tool geometry.
I like the Engineers Black Book and keep it handy in the shop. But it also has some shortcomings, like MH. One of those shortcomings that I find is strange that no one has bothered to put together in one table is the information needed for screw holes. By "all" the information I mean things like coarse and fine tap sizes, tap drill size for both, loose and tight clearance hole sizes, counterbore diameter and depth, countersink diameter at surface, etc. EVERYTHING needed to draw and make a screw hole. Oh, and English and metric, of course. No one has all that in one chart. NO ONE! I have begun making my own: it is a work in progress.
