hollow drill steel
The hollow drill steel is vital material for making drill rods. It is typically supplied as steel hollow bars that made from premium grade steel and through closely-controlled metallurgical process. The result is quality hex hollow drill steel with increased hardenability, uniform grain structure, and excellent machinability, which is difficult to break.
Drill rods made of Roschen hollow steel bars deliver stable drilling performance and extended wear life.
