| description | The present invention relates to an auger hammer bit expected to have a reduced construction period for a pile construction of continuous wall, and reduced construction cost by vertically drilling while easily crushing an overlapped part on the rim of two adjacent columns constructed beforehand. The auger hammer bit according to the present invention comprises: an air hammer formed with a screw connected to an auger screw formed on a screw arm as installed in a lower end of the screw arm of an auger drill; a screw for excavation formed to be placed apart from a screw formed on the air hammer, on an external part of a hammer bit installed on the air hammer; and a ring bit coupled to a lower part of the screw for excavation, and wherein a bit is concentrically formed at a lower end. |
