SOLDERED MACHINING TOOL AND SOLDERED BAR STOCK FOR FORMING THE SOLDERED MACHINING TOOL

摘要

A soldered bar stock has a handle blank with a first through hole, and has a head blank having a soldered portion protruding into and soldered in the first through hole. The soldered bar stock is machined to form a soldered machining tool. With the first through hole formed in the handle blank, the head blank can be firmly soldered to the handle blank. When replacing the head blank with a new one, solder in the first through hole can be completely cleaned. Moreover, when using the soldered machining tool, a cooling liquid can be injected into the first through hole to cool down the soldered machining tool.
