Versatile Replaceable System [VRS]

Hole Opener

 

Versatile hole opener with centralisation: This roller-cone embedded hole opener is intended for soft to very hard formations where 'crushing' the rock is superior to shearing. Our hole opener is equipped with one of its kind spiral centralisations, which enables smoother drilling.

FEATURES

  • The shaft is made from a single piece of AISI 4140 steel, reducing the possibility of cracking.
