keyway tolerances
(OP)
Can anyone advise what tolerance class should be used on the bore of a bore and keyed coupling i.e H8?

Advice from lecturer: "Be warned - when you go into industry your boss will give you a thousand things to do and he wants them done yesterday!" So far he is right...
RE: keyway tolerances
For shafts 10 to 22mm diameter the keyway/key depth tolerance is +0.1mm and it is +0.2mm for shafts 22 to 110mm diameter.

Square key steel ISO tol. field h9.
For keyways:
DIN 6885 T1, T2, T3
On shaft: Tight fit P9, light fit N9
In bore: Tight fit P9, light fit JS9
Based on ISO Recommendation Nr. 1084 - Rectangular and square keys and their corresponding keyways.
RE: keyway tolerances
If you are looking for the shaft and bore than you need to tell us more about what kind of fit you are looking for (press, sliding etc.).
RE: keyway tolerances
Would you still use ISO tolerances on imperial shafts and bores?
