当今，高速发展的现代工业要求有高速精确的切削工具，而代表高技术的螺旋油孔钻就可以满足这一要求。螺旋油孔钻对传统实心钻具有很大的改进。传统螺旋钻头有几个不足之处：－钻头中心设速度、无法切削。－切削角度和速度的变化使钻刃变干．发热和磨损。－由外面注入的起冷却
Today’s fast-paced modern industry requires high-speed, accurate cutting tools, and high-tech screw hole drills meet this requirement. Spiral hole drilling on the traditional solid drill has greatly improved. There are several disadvantages of conventional helical bits: - The speed at the center of the drill bit can not be cut. - Cutting angle and speed changes make drilling edge dry. Fever and wear. - From the outside into the cooling
