Tapered drill rod is suitable for small pneumatic rock drills or hydraulic rock drills for shallow hole drilling operations, and are generally made of H22 and H25 hexagonal hollow drill steel. The tapered drill rod needs to be matched with the taper drill bit for rock drilling, and It is usually used in rock drilling operations in quarries, coal mines, roadbeds, construction and other fields. Conventional taper angles for tapered drill rods are 7°, 11°and 12°.
The tapered drill rod is an essential tool for drilling operations, featuring a unique tapered design at both ends that efficiently transmits the axial thrust of the jackhammer, enabling the tapered drill bit to deliver powerful breaking performance.
Manufactured from specially selected alloy steel, it undergoes precise forging, rigorous heat treatment, and surface strengthening processes to achieve high hardness and toughness.
