ISO Approval Tapered Drill Rod Hex 22 X 108mm 25 X 159mm For Small Hole Range

ISO Approval Tapered Drill Rod Hex 22 X 108mm 25 X 159mm For Small Hole Range

Tapered drill rod,also 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.

Our Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Drillers choose tapered button bits for faster drilling penetration rate. Different taper sizes have different characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning.

Our Tapered drill rods are made from the best steels and alloys in China,from 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.
