    Abstract: A cutting insert used primarily as the gauge inserts for a rock drill bit preferably for percussive rock drilling is disclosed. The cutting insert can also be adapted to roller bits. The insert is provided with a cutting edge(3) on its domed or ballistic surface. When such inserts are mounted on the rock drill bit, the cutting edges are towards the wall of the drilled hole. The rock drill bit impacts the same as prior bit designs, but the cutting edge cuts away rock instead of spalling away the rock. This therefore prolongs the life of the inserts. Also, a roller cone rock drill bit is disclosed.

    Abstract translation: 公开了一种主要用作用于凿岩钻头的计量插入件的切削刀片，优选用于冲击式钻岩。 切削刀片也可以适用于滚子钻头。 插入件在其圆顶或弹道表面上设置有切割边缘（3）。 当这种插入件安装在岩石钻头上时，切割边缘朝向钻孔的壁。 凿岩钻头与现有的钻头设计相同，但切削刃切割岩石而不是剥落岩石。 因此延长了刀片的使用寿命。 另外，公开了一种滚子凿岩钻头。
