introduction：shenkongzuan Deep hole drill deep hole drill Drill bits specially designed for deep hole machining。In machining, the ratio of hole depth to aperture is usually greater than6The hole is called a deep hole。When drilling deep holes,Heat dissipation and chip removal are difficult，And because the drill pipe is slender and rigid，Prone to bending and vibration。Pressure cooling systems are generally used to solve cooling and chip removal problems。The deep hole drill is divided into two categories according to the chip removal method: external chip removal and internal chip removal。There are gun drilling deep hole flat drill and deep hole twist drill and so on;Internal chip removal depends on the processing system used，pointsBTA(Boring an
