Product Description

Product Description

 

Rock drilling tools Tapered Drill Rod is to provide 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 drill bit end. Tapered steel lengths are measured from the collar to the bit end. Holes are usually drilled in 0.6 m increments to accommodate the air leg feed length. The drilled steel is extracted and followed with a slightly smaller diameter rock drill bit on the next steel length in the sequence.

Carburization is a process used to harden the entire tapered drill rod surface both internally and externally to strengthen and extend the life of the tapered drill rod.
Shank Hexagon: 19*108 mm, 22*108mm, 25*108 mm, 25*159 mm; 6, 7, 11, 12 degree taper in most lengths, taper degree of drill steel is mostly imports for excellent drilling productivity.
