Core barrels are circular cutting devices used to cut hard surfaces like seabeds and concrete. There are three types: standard, diamond, and rotary. They are made of hardened materials and have cutting teeth. Rotary barrels are used for hard rock and diamond barrels use a diamond tip.
A core barrel is a circular design cutting device with an open center. This piece of machinery is typically used to cut extremely hard surfaces, such as seabeds with rock bottoms and steel reinforced concrete. There are three main types of core drills: standard barrels, diamond barrels, and rotary barrels. This type of equipment is typically used by industrial construction companies and geological survey teams.
The core barrel is typically mounted on stabilization equipment, such as a drilling rig or truck, which can be operated by fewer workers and used for smaller cores. The barrel itself is made from a variety of hardened materials, such as steel and titanium, designed to withstand large amounts of pressure, and features a row of cutting teeth along the bottom edge. The teeth can be made of materials similar to the drill itself and are often reinforced with additional heavy-duty metals. These drills are manufactured in a variety of sizes and can often be designed to the purchasing company’s specifications. Some types of drills are equipped with an additional internal drill core.
A rotary core barrel is a two-part drilling system composed of a rotating bit that moves around a non-rotating inner core. This type of drill is often used to penetrate hard, crusty rock on the ocean floor, and is often used on offshore oil rigs for well drilling. The drill rests on the rock surface and begins to rotate downward into the hardened sediment. The non-rotating inner core can be inserted periodically to take rock samples for analysis. The fixed core can be removed at any time and replaced with a secondary rotary drill for added strength.
A diamond core drill is similar to a rotary core. It employs an inner and outer core to obtain rock and mineral samples during the drilling process. The diamond drill bit, however, is used where materials are too hard for a standard rotating cylinder to penetrate. The diamond tip can be inserted into the existing well, then rotates the outer barrel around the inner barrel to cut away the sample. This technique is also useful for preventing external water from entering the core sample during the extraction process, which is a primary concern when drilling in the ocean.
