Product Description:
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°.
Features:
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.
