The choice of the material, section shape, geometric size and length of the rock drill steel rod is based on the size of the impact power of the drill steel, the hardness of the rock, the diameter of the drill bit head, the depth of the rock hole, the connection requirements of the shank adapter, and the feeding mode of the drill rod. Usually, in the premise of meeting the requirements of rock drilling, we should try to select a moderate section, good rigidity, and long life of the rock drill steel rod. Litian rock drill steel rod is made of high-quality raw materials and a special heat treatment process, which can effectively reduce the risk of dents in the threaded part. The production and processing of more precise manufacturing tolerances make our rock drill steel rod of higher quality and more durable.
