In the UK, house construction is divided into separate stages "first fix" and "second fix"
first-fix includes carpentry that the eventual occupier of the house won't see. For example the woodwork inside stud-walls. It is expected and normal that this isn't finished to the standard you would expect of a second-fix carpenter and not to the standard you would expect of a joiner or cabinet-maker.
Some saw-makers sell "first-fix saws" and "second-fix saws". First-fix saws have fewer teeth per inch and cut faster but leave a rougher cut edge.
This distinction between visible and hidden work is probably similar where you live, though terminology will differ.
