摘要： A rotating bit with cutters used in drilling operations to advance a borehole in the earth. The bit includes column cutters in the bit body in a recessed central area. The column cutters contact a column of borehole material that is formed during operation. The column cutters are oriented to fracture the column, producing larger cuttings or chips, and to exert a force on the column to limit lateral movement of the bit during operation.
摘要翻译：旋转钻头，用于钻孔作业中的切割器，以推进地球中的钻孔。该位在凹陷的中心区域中的钻头体中包括列切割器。柱切割器接触在操作期间形成的钻孔材料柱。柱切割器被定向成使柱断裂，产生更大的切屑或碎屑，并且在柱上施加力以限制钻头在操作期间的横向运动。

摘要： Cutters mounted on bits for advancing boreholes are subject to extreme forces that can separate the cutter from the bit. A cutter backing element with a rearward extending lug and forward face can provide support to the cutter. The backing element is attached to the back face of the cutter and the lug of the backing element is received in a recess of the bit. The backing element can be brazed to the bit a nd the cutter. The lug is offset from a longitudinal axis of the backing element. Forces applied to the front of the cutter during drilling operations are transferred through the cutter to the backing element and to the bit through the offset lug.
摘要翻译：安装在钻头上用于推进钻孔的刀具受到极大的力量的影响，刀具可以将钻头与钻头分离。具有向后延伸的凸耳和前表面的切割器背衬元件可以为切割器提供支撑。背衬元件附接到切割器的背面，并且背衬元件的凸耳被接收在钻头的凹部中。背衬元件可以钎焊到刀头和刀具上。凸耳偏离背衬元件的纵向轴线。在钻孔操作期间施加到切割器前部的力通过切割器传递到背衬元件并通过偏移凸耳到达钻头。
