Abstract
The utility model belongs to mechanical manufacturing equipment, in particular to a trepanning tool bit for a hollow drilling machine, which comprises a tool bar and a tool ring, wherein the tool ring is arranged on the tool bar, and one end of the tool bar and one side of the tool ring are in a tapered shape. The trepanning tool bit is characterized in that the tool bar is in a hexagonal prism shape, and one end of the tool bar is provided with a slot for installing a tool blade. Compared with the existing trepanning tool bit for the hollow drilling machine, the utility model has higher toughness and surface contact strength, and long service life of more than 40 hours generally.
Description
Technical field:
