Zeus Precision Data Charts and Reference Tables for Drawing Office, Toolroom & Workshop

85 mm x 155mm (3 1/3" x 6 1/4").Quick look up for stuff you rarely use or don't want to risk remembering wrong. Tap and clearance drill sizes for me. Good purchase.I do believe there are a couple of typo's in the Selected ISO FIT_HOLE tables.Clearance fit table look OK but:1: Both Transition fit and Interference fit tables are labelled as Transition fit2: In these diagrams for these tables both Holes and Shafts are marked as holes (right diagonal fill)OK Hole sizes always start with an H and most of us will read the Calorie count on None alcoholic beer more often. However they are side by side rather than one above the other, as Clearance fit, so it is a bit unclear.

It has all the conversions you need.

All the information you ever need

I bought this for my grandson who is keen on engineering. I always have a copy in my toolbox.

Got given one of these 20 years ago when I started my Engineering apprenticeship, brilliant little book. Unfortunately some beggar nicked mine last month so had to buy another.

Great for someone working in plating fits into a pocket so easy to get to aswell

Just what I wanted. Thanks

Old book over 50 years old needed new one excellent.

This is just what I have been looking for. It arrived very quickly and this may well be the best packing I have received.... I will recommend to all.Thanks,Ed

An essential item for apprentices, still own and use mine from the 70's.

I used to keep one in my top pocket when I when I was a Toolmaker!

pocket info for the machine trade.

If you are looking for one of these you already know what it is. I know you can google everything but sometimes that is not convenient with greasy hands
