What is a hole opener? A hole opener can be defined as a fixed diameter bore hole enlargement tool that is used to expand a well bore beyond its original hole size drilled by the bit. Different types of PDC hole openers are used for different applications. These are stable, vibration free, have a longer service life, and there is no fear of losing the cones. The major function of a PDC hole opener A PDC hole opener is usually used after the pilot bit has drilled the original hole. It can either have a body with roller cones or it could be a fixed blade that would be dressed with PDC. Where are these used? A hole opener is tripped into the well bore to the beginning depth and then utilized to enlarge the pre-drilled pilot hole. This is the most common use of a hole opener, however, they may be also utilized to ensure that the gauge of the pilot hole is intact through a method called a wiper trip. Wiper trips are suited well for deviated holes where trying to run the bit back to the end...

Hole openers and drill bits are closely related. A hole opener can be defined as a fixed diameter tool that is commonly used in drilling larger top hole sections where there are no restrictions. 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...

Before we delve deep into the comparison between tricone drill bits and PDC drill bits, it is important to understand what drill bits actually are. There exists a drill bit for just about every application, from simple bits for drilling into sheet metal on home projects, to specialized tungsten carbide diamond impregnated bits for drilling into hard rock formations . Knowing which drill bits are the most efficient comes with years of drilling experience and research. Tricone drill bits have been in the market way before rock-shearing bits like PDC ’s came into existence. While the drilling bit PDC may be a relative newcomer to the drilling industry, its strength and solidity have enabled it to hit the ground running on a number of fronts : 1.       Live Long and Prosper While tricones require a lower the initial investment, PDC bits can be more cost-effective in the long run, thanks to the fact that their greater lifespan equates to a less frequent b...
