[0005] The three-blade deep hole drill provided by the application is provided with a twist drill bit at the front end of the first drill handle, the twist drill bit is a common type of drill bit, which is used for drilling metal and other materials. The rear end of the first drill handle is connected with the second drill handle, and the diameter of the second drill handle is different from that of the first drill handle, which is to adapt to different processing requirements or provide better mechanical properties. The reinforcing strips uniformly distributed on the side wall of the second drill handle can enhance the rigidity and durability of the drill bit, prevent deformation or fracture during drilling, and ensure the processing quality and guarantee the processing efficiency.
[0006] In a possible implementation manner, two flat-bottom notch grooves are symmetrically arranged on the side wall of the second drill handle, and the flat-bottom notch grooves are arranged at the end of the second drill handle. The two flat-bottom notch grooves symmetrically arranged at the end of the second drill handle facilitate installation and driving.
[0007] In a possible implementation manner, the surface of the reinforcing strip is a circular arc surface, and the distance between the two ends of the reinforcing strip and the corresponding two ends of the second drill handle is greater than 0.6 cm. This scheme ensures that the reinforcing strip provides sufficient support and protection without affecting the overall structural strength of the drill bit.
[0008] In a possible implementation manner, the diameter of the second drill handle is smaller than that of the first drill handle.
[0009] In a possible implementation, the end of the first drill handle is provided with a protruding structure, the second drill handle is connected to the protruding structure, and the side wall of the protruding structure is connected to the side wall of the first drill handle through an arc-shaped connecting surface. This design can improve the overall strength and stability of the drill bit, and also helps to maintain the straightness and accuracy of the drill bit during drilling. BRIEF DESCRIPTION OF DRAWINGS
