The term denotes a digital document, typically in Portable Document Format, providing information about various kinds of drilling tools. Such a document often contains descriptions, illustrations, and specifications related to different drill bit designs and their applications.
Accessing this information offers multiple advantages. It allows for informed selection of the appropriate tool for specific drilling tasks, potentially improving efficiency and reducing the risk of damage to materials or equipment. Historically, printed catalogs served a similar function, but the digital format allows for easier distribution, searching, and updating of information.
