high quality tapered rock drill steel rod and mining tapered hex
drill rod
Our Mission : Better solution and Lower cost
Our Vision : Trust and Reliabity,
Our drills are made from the best steels and alloys in the country.
Japan or Germany CNC lathe thread and drilling alloy perforations
to ensure the accuracy of the ball tooth bit. Advanced thermal
inlay technology ensures that the quality of each ball bit is
stable.
The ball tooth bit uses different alloy teeth (hemispherical teeth,
bullet teeth, parabolic teeth, etc.) according to different rock
formation structures and hardness. We can make alloy ball tooth
drills of different specifications and different forms according to
different needs of users. Widely used in mining, tunneling,
underground plant excavation and other construction sites. It is an
ideal substitute for the same type of ball tooth bit in foreign
countries, with stable quality and high cost performance.

Technical Reference
Tapered drill rod,another name called taper rod, tapered drill
steels, This provides a hexagonal chuck section to provide leverage
for the rotation chuck bushing. It usually has a forged collar to
maintain the proper shank striking face position in the rock drill,
and a tapered bit end. Tapered steel lengths— available from 0.6
mto 3.6 m in length—are measured from the collar to the bit end.
