  • Patent number: 3934319
    Abstract: Improved point geometry is provided for cutting inserts wherein the insert point is subjected to physical and thermal shock in first contacting the stock to be cut and is particularly applicable to cemented carbide or hard metal inserts. It has been found that the provision of about a 104.degree. included angle at the initial work-contacting or lead portion of the insert tip provides improved resistance to physical and thermal shock and longer insert life. While the new cutting insert is especially useful in interrupted cutting where the insert is continuously engaged and disengaged as in the case of a series of cutting inserts in a milling head in contacting an uneven surface, it is also applicable to boring and turning operations and to continuous cutting where the insert point is stressed.
