Fixed Diameter Hole Opener

Technical Features

Fixed diameter hole openers are used for expanding the drilled hole. The cutters are manufactured under the severe quality control. All our hole openers are field maintainable, with easy assembly and disassembly. They are all equipped with 3 or 4 cutters, as well as mud nozzles precisely located to clean the cutters and the hole simultaneously.

They are used for the following purposes:

1. When drilling of the big hole is not possible because of the rig capacity.

2. When a satisfied penetration rate is not obtained in case of the big hole drilling, it is used after drilling with smaller bit.

3. When the hole direction must be controlled.

When ordering please specify:

l Hole size to desire;

l Pilot hole size;

l Top and bottom connections;

l Fishing neck and bottom neck O.D and length;

l Type of cutters.
