Carbide twist drill 5XD is our standard drill with shorter flute length, widely used for drilling workpiece with shallow holes.
Carbide drill bits with coolant through, mostly used for drilling stainless steel, cause stainless steel is a hard material, a lot of heat generated during the drilling process, coolant-fed can cool down the drill, to extend the tool life.

In the machining of the main water guiding parts of the turbine (see Figure 1), it is required that the center of the vane shafts at both ends coincide with the center of the vane body line. In the process, we use the guide vane (Fig. 1) to find the center of the guide vane line. The vane body is placed on the positioning plate of the tire, and the center hole of the guide vane at both ends is drilled. For the positioning reference, the outer diameter of the guide vane shaft and the end face of the vane body are processed. The positioning profiles of the vane body are machined on the two positioning plates of the tire according to the shape of the guide vane. The focus of the tire processing is to ensure that the two positioning profile lines overlap in the P-direction view.
