2. The spiral lead of the spiral of the double spiral chip groove of the spiral groove drill needle for the thread binding machine is larger than 3cm, is a typical large helix angle, is convenient for discharging paper scraps in the punching process, and can be suitable for punching thicker bound documents.

3. According to the spiral groove drill needle for the thread binding machine, the thread hanging hook groove stop head is integrally arranged at the front end of the thread hanging hook groove, so that the limiting effect on cotton threads penetrating into the thread hanging hook groove can be realized, the cotton threads are prevented from falling out of the thread hanging hook groove, and the smooth binding operation is ensured.

4. According to the spiral groove drill needle for the thread binding machine, the thread hanging hook groove is internally provided with the anti-skidding lines, so that the friction force between the cotton thread and the thread hanging hook groove is increased, the cotton thread can stably pass through a drilled hole without falling off in the threading process, and the binding efficiency is improved.

5. According to the spiral groove drill point for the thread binding machine, the top end of the drill handle part is provided with the round chamfer, so that the smoothness of the handle part of the drill is improved, the drill point is prevented from being scratched due to a sharp corner when the drill point is taken and installed by a hand, and the operation safety is improved.
