Product Description

Horizontal Directional Drilling hole openers are also known as HDD reamers which used to enlarge the pilot hole in Horizontal Directional Drilling (HDD).HDD is used in trenching and excavating is not practical. This drilling technology allows for a steerable trench-less way to underground.
 

ADC	Rock formation	WOB (KN/mm)	PRM(r/min)
