The present invention pertains to a coring device for a material of high strength and high hardness, and provides a coring device, wherein stable straightness without shaking is assured and force applied in the vertical direction is improved while coring work for a material of high strength and high hardness is performed such that an innovative work time reduction is enabled, and an improvement of processing yield and reduction of manufacturing costs can be achieved. According to the present invention, the coring device includes a conveyor main body (40) which conveys a core motor (63) and a core (64) in the vertical direction while fixing and supporting the same; and a pair of vertical columns (30) standing in the vertical direction which respectively penetrate and are coupled at both right and left ends of the conveyor main body (40). Therefore, the upper and lower vertical conveying operations of the conveyor main body (40) are guided by the vertical columns (30) such that the conveyor main body (40) is prevented from shaking and twisting, and the one pair of vertical columns (30) are mounted having a structure in which the columns (30) are arranged in diagonal lines separated in both the right and left direction and the vertical direction. |
