What type of notes communicates specific features such as chamfer angles and hole diameters in manufacturing prints?

Local notes are used in manufacturing prints to communicate specific features directly related to a particular section of the drawing. These notes provide detailed information such as dimensions, chamfer angles, and hole diameters that pertain to localized areas of the design. They are typically positioned near the relevant features, making it easier for machinists and fabricators to understand the requirements without having to reference multiple sections of the drawing.

In contrast, standard notes generally cover commonly accepted practices and specifications that apply broadly across many drawings without being specific to any particular feature. Detailed notes, while they may provide in-depth explanations, are less specific than local notes and tend to refer to entire processes or sections rather than particular features. General notes encompass wide-ranging instructions or reference standards that apply to the entire print or multiple features but do not provide the focused detail required for specific dimensions or features.
