            The scientific and standard thread profile design is the basis for the high quality threaded connection of the drill products, and the production of the thread size accuracy is the only way to ensure the excellent performance of the threaded connection. Inaccurate thread connection, too large or too small a gap, will cause high frequency vibration and sway of the threaded part of the drill during rock drilling, resulting in local high temperature, resulting in broken thread.
