Hole openers are used in almost all facets of drilling water wells for actually enlarging the hole, to act as a stabilizer, or to use for a wiper trip (ensure the hole is to gauge). These usually are run with roller cones but as the hole sizes get smaller, some people prefer to use a bladed hole opener which does not use roller cones. Notably, hole openers can also be customized to suit our requirements. A lot of people consider a hole opener to be dumb iron as there are no moving parts but the fact is a lot of engineering that goes into them. Even thoughhole openers have not changed much in appearance since their inception, the roller cone cutters have gone through many changes to increase the drilling life of the tool. There are a lot of companies out there who have not only designed a...
