Powerful API Hole Openers
Roschen Hole openers allow the drilling of large bores even with a relatively low rig capacity, thus reducing drilling costs. By enlarging a pilot bore, they lower the torque on the drill string and assist in drilling a straighter hole. Manufactured from a single piece of full-length heat treated AISI 4145H steel, our hole opener withstands extreme force during drilling.
Content Overview
1. A Hole Opener for Every Formation
2. Easy Maintainability
3. Reduced Drilling Costs
A Hole Opener for Every Formation
Depending on its size, each of our hole openers is equipped with 3
or 4 cutters. Cutters are available as both milled tooth and
Tungsten Carbide inserts (TCI) bits.
Milled tooth can be used for soft to medium formations while TC
inserts are ideally suited for hard formations. Mud jets clean the
cutters, increase reaming efficiency, and prevent balling problems.
Easy Maintainability
Due to its rigid design, the body of our hole opener almost needs
zero maintenance. Cutters are changed quickly on the drill floor
without the need for special tools.
Production strictly follows API Spec 7-1, thus further assuring
quality.
Reduced Drilling Costs
Except for the cutters that are replaced easily, our hole opener
does not have any wear parts, resulting in an extended service life
and low maintenance costs.
The fact that hole openers allow the reaming of large holes with
less powerful equipment makes it possible to significantly cut
operation costs.
