A chisel according to an embodiment of the present invention comprises: a chisel body having a core insertion groove formed thereon; a core inserted in the core insertion groove; and a cushion member inserted in the core insertion groove and located between the core and the chisel body. The chisel includes a core configured by a unique composition and thus has improved durability. Further, the cushion member located between the core and the chisel body prevents the chisel from being broken due to pressure concentration and thus prolongs the lifespan of the chisel.
Un burin selon un mode de réalisation de la présente invention comprend : un corps de burin présentant une rainure d'insertion de noyau formée sur celui-ci; un noyau inséré dans la rainure d'insertion de noyau; et un élément d'amortissement inséré dans la rainure d'insertion de noyau et disposé entre le noyau et le corps de burin. Le burin comprend un noyau constitué d'une composition unique et présentant ainsi une durabilité améliorée. De plus, l'élément d'amortissement disposé entre le noyau et le corps de burin empêche le burin d'être cassé en raison de la concentration de pression et prolonge ainsi la durée de vie du burin.
본 발명의 일실시예에 따른 치즐은 코어 삽입홈이 형성된 치즐바디과, 상기 코어 삽입홈에 삽입된 코어와, 상기 코어 삽입홈에 삽입되고 상기 코어와 치즐바디 사이에 위치되는 완충재를 포함하고, 특유의 조성으로 이루어지는 코어를 포함하여 내구성이 향상되고, 코어와 치즐바디 사이에 완충재를 위치시킴에 따라 압력집중에 따른 파손이 방지되어 수명이 향상된다.
