Abstract
An insert made of an ultra-high-pressure sintered compact and including no base metal or support layer is brazed to a tool body under vacuum by use of a Ti-containing activated silver brazing filler metal. This method permits the insert to be securely fixed to the tool body without fear of the insert coming off the tool body even if the tool is a helical one. Because no base metal layer is needed, the manufacturing yield, efficiency and productivity are improved.
