Drilling tool
钻孔工具,特别是凿岩钻头,具有一柄部(2),其一端连接在用于钻削器械刀夹的插入端上,其另一端具有一至少带两条由硬质合金构成的刀刃(5)的钻削头(4),刀刃径向突出于钻削头(4)的圆周。头部排屑槽(7)至少部分分布在硬质合金刀刃(5)之间,头部排屑槽通入至少一条螺旋形地环绕柄部(2)的排屑槽(3)内。钻削头(4)的结构做成这样,使钻削头(4)至少在两条硬质合金刀刃的区域内具有一扩展的外围轮廓(8),它径向突出于柄部(2)的圆周(9)。 The drilling tool has a shaft (2) with a drill head (4) with at least two cutters...

Summary: | 钻孔工具,特别是凿岩钻头,具有一柄部(2),其一端连接在用于钻削器械刀夹的插入端上,其另一端具有一至少带两条由硬质合金构成的刀刃(5)的钻削头(4),刀刃径向突出于钻削头(4)的圆周。头部排屑槽(7)至少部分分布在硬质合金刀刃(5)之间,头部排屑槽通入至少一条螺旋形地环绕柄部(2)的排屑槽(3)内。钻削头(4)的结构做成这样,使钻削头(4)至少在两条硬质合金刀刃的区域内具有一扩展的外围轮廓(8),它径向突出于柄部(2)的圆周(9)。
The drilling tool has a shaft (2) with a drill head (4) with at least two cutters (5) of hard metal. The cutters project radially from the edge of the drill head and have dust grooves (7) at least partly between them, which open into at least one spiral conveying groove (3) along the shaft. The bore head has an expanded peripheral contour (8) at least in the area of two of the cutters, which projects radially over the edge (9) of the shaft. |
