To provide a drilling head and a drilling device with a configuration that do not require a lot of energy when making excavation abilities function and that can make a cylindrical hole stably and quickly.SOLUTION: The drilling head that comprises: a rod 1 that is retained by a chuck C of a drill D; a spiral blade 2 that is positioned on the tip of the rod 1 and pivots on the rod 1; and an agitation blade 3 that is supported on the rod 1, and pivots on the rod 1 and rotates with and around the spiral blade 2, and the drilling device including the drilling head are provided.SELECTED DRAWING: Figure 7
【課題】掘削能力を機能させる際に多大なエネルギーを必要とせず、円柱状の穴を安定的に、且つ速やかに開けることができる構成を持った穴掘り用ヘッド及び穴掘り装置の提供。【解決手段】ドリルＤのチャックＣに保持されるロッド１と、前記ロッド１の先端に配置され当該ロッド１を軸として回転する螺旋刃２と、前記ロッド１に支持され当該ロッド１を軸として当該螺旋刃２と共にその周囲を旋回する撹拌刃３を備える穴掘り用ヘッド及びそれを装着した穴掘り装置。【選択図】図７
