Introduction

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 equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Different taper sizes have different characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning.

 Produstion Type

Shank Hexagon:25 x108 mm, 6, 7, 11, 12 degree taper in most lengths, taper degree of drill steel is mostly imports for excellent drilling productivity.
