<p>The present invention relates to a portable boring machine capable of being small, light, and portable to bore a hole on a large material which is hard to move. The portable boring machine comprises: a driving motor (110) arranged in one side of a cover (10, 20), and generating rotation power; a cylindrical rotation housing (120) arranged inside the cover (10, 20), having a shaft rotation gear (122) arranged on the outer surface and rotated by the power of the driving motor, and rotated by the rotation of the shaft rotation gear (122); a transmission gear (130) for transmitting the power of the driving motor (110) to the shaft rotation gear (122); a shaft (200) inserted through the rotation housing (120), and rotated along the rotation of the rotation housing (120); a boring tool (210) coupled to one side of the shaft (200), and boring the hole (H) in one side of the material (M) while being rotated with the shaft (200); and a moving unit (300) arranged in the other side of the shaft (200), and linearly moving the shaft while supporting one end of the shaft (200) to be rotated. The boring machine enables the reduction of entire size and weight, thereby freely changing the installation position and angle of the boring machine at desired positions where workpieces are positioned.</p> |
