Tapered drill rod is a further development of the integral drill rods. It usually has a forged collar to maintain the proper shank striking face position in the rock drill.

With one side connected to rock drill and the other side connected with taper drill bit, the taper drill rod transmits power from rock drill to bit, drilling work is thus performed. Tapered drill rod is a further development of the integral drill rods. It usually has a forged collar to maintain the proper shank striking face position in the rock drill. Tapered drill rod effective lengths are measured from the collar to the bit end, which are usually from 0.6meter to 3.6 meters.

Parameters

• Shank sizes: Hex.19mm, Hex. 22mm, Hex.25mm
• Taper degrees: 4°46’, 6°, 7°, 11°, 12°.
• Length: 400 - 8000mm.

Features

• The carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;
• 23CrNi3Mo, which is in the same league as Sandvik Sandbar 64, is applied as drill rod material.
• Cost-effective, good performance with reasonable price.
• Complete types of drill rod for various drilling scenarios.

Integral drill steel rod is used by a hand-held drill machine in underground mining and for small hole drilling, equipped with small power rock drills, like air leg rock drills, hand-held rock drills, etc. According to different applications, different lengths are available

Fully-carburized Taper Drill Rod is to increase the surface carbon content of the drill rod through the carburization craft, level up the surface hardness and the overall strength, and increase the service life of the taper drill rod. Compared with the conventional taper drill rod, Fully-carburized Taper Drill Rod is high in strength and good in abrasive resistance. Under the same industrial and mining, the life of fully-carburized taper drill rods is times of that of the common taper drill rods.
